description Publicationkeyboard_double_arrow_right Article , Journal 2016 BelgiumPublisher:Institute of Electrical and Electronics Engineers (IEEE) Authors: Druant, Joachim; De Belie, Frederik; Sergeant, Peter; Melkebeek, Jan;handle: 1854/LU-6972463
An electrical variable transmission (EVT) is an electromagnetic device with dual mechanical and electrical ports. In hybrid electric vehicles (HEVs), it is used to split the power to the wheels in a part coming from the combustion engine and a part exchanged with the battery. The most important feature is that the power splitting is done in an electromagnetic way. This has the advantage over mechanical power splitting devices of reduced maintenance, high efficiency, and inherent overload protection. This paper gives a conceptual framework on how the torque on both rotors of the EVT can be simultaneously controlled by using a field-oriented control (FOC) scheme. It describes an induction-machine-based EVT model in which no permanent magnets are required, based on classical machine theory. By use of a predictive current controller to track the calculated current reference values, a fast and accurate torque control can be achieved. By selecting an appropriate value for the flux coupled with the squirrel-cage interrotor, the torque can be controlled in various operating points of power split, generation, and pure electric mode. The conclusions are supported by simulations and transient finite-element calculations.

The rotor design of Synchronous Reluctance Motors (SynRMs) has a large effect on their efficiency, torque density and torque ripple. In order to achieve a good compromise between these three goals, an optimized rotor geometry is necessary. A finite element method (FEM) is a good tool for the optimization. However, the computation time is an obstacle as there are many geometrical parameters to be optimized. The flux-barrier widths and angles are the two most crucial parameters for the SynRM output torque and torque ripple. This paper proposes an easy-to-use set of parametrized equations to select appropriate values for these two rotor parameters. With these equations, the reader can design a SynRM of distributed windings with a low torque ripple and with a better average torque. The methodology is valid for a wide range of SynRMs. To check the validity of the proposed equations, the sensitivity analysis for the variation of these two parameters on the SynRM torque and torque ripple is carried out. In addition, the analysis in this paper gives insight into the behavior of the machine as a function of these two parameters. Furthermore, the torque and torque ripple of SynRMs having a rotor with three, four and five flux-barriers are compared with three literature approaches. The comparison shows that the proposed equations are effective in choosing the flux-barrier angles and widths for low torque ripple and better average torque. Experimental results have been obtained to confirm the FEM results and to validate the methodology for choosing the rotor parameters.

The goal of this paper is to evaluate additional harmonic losses in relation to the machine's initial efficiency rating. However, due to the relatively small amount of additional loss, the main drawback when evaluating the effect of supply voltage distortion on the machines' overall efficiency is the measurement accuracy of the current methods. In order to validate the effect of motor efficiency rating in relation to supply voltage distortion, the use of the parameter "harmonic active power" is suggested. This new strategy is subsequently validated by measurements and compared to current methods such as the NEMA MG1, or the procedure according to the IEC60034-2-3. Although this strategy is only valid under certain constraints, this new method enables a fast and highly accurate measurement of the additional loss. Consequently, this parameter is used to validate the effect of efficiency rating of induction motors in relation to the additional loss related supply voltage distortion.

The aim of this paper is to calculate the static eccentricity (SE) of a double rotor axial flux permanent magnet (AFPM) machine by using a general analytical model. The flux density in the air gap under healthy conditions is calculated firstly, where the axial and circumferential magnetic flux densities are obtained using a coupled solution of Maxwell’s equations and Schwarz-Christoffel (SC) mapping. The magnetic flux densities under SE conditions are calculated afterwards using a novel bilinear mapping. Some important electromagnetic parameters, e.g., back electromotive force (EMF), cogging torque and electromagnetic (EM) torque, are calculated for both SE and healthy conditions, and compared with the finite element (FE) model. As for the double rotor AFPM, SE does not contribute much effect on the back EMF and EM torque, while the cogging torque is increased. At each calculated section, FE models were built to validate the analytical model. The results show that the analytical predictions agree well with the FE results. Finally, the results of analytical model are verified via experimental results.

The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal that the additional loss due to unbalanced loading is partially dissipated in the rotor. Because analytical segregation of the individual loss components remains complex due to the skin effect in the rotor bars, Finite Element Modeling is used to accurately model the loss, inherently taking into account the skin effect. The results obtained by Finite Element Modeling are compared to practical measurements and are consequently used to evaluate the possibility of deriving lumped electrical models.

ESP System (ESPS) consists of several components: surface components and underground components. The surface components include an electric power supply, a transformer, a control board, and a control valve. The underground components include a centrifugal pump, an electric motor, a cable, and sensors. The existence of the components down the well exposes the system to severe challenges. The challenges that must be taken into account are several, such as depth, high temperature, high pressure, limited well diameter, corrosive surrounding material, high flow rate and high power consumption. In this paper, a comprehensive review of the ESPS is presented. It aims to provide a broad perspective on the various components of the ESPS and the trends to tackle the challenges of this type of systems.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Conference object , Article 2022 BelgiumPublisher:IEEE Authors: Mohamed N. Ibrahim; Peter Sergeant;This article compares three drivetrains for the shedding mechanism of weaving loom applications, which have a strongly oscillating load pattern. The three drivetrains employ a permanent magnet motor without a gearbox. The first drivetrain uses only the electric motor (EM1) while the other two drivetrains use the electric motor with assistance of a separate or an integrated magnetic spring (EM2MS or EMMS respectively). The magnetic spring provides part of the load torque in a passive way. This results in a reduced power consumption. The optimal design and the performance analysis of the machines have been presented for the considered application using a 2D finite element model coupled with an optimization algorithm. To validate experimentally the theoretical results, the EMMS prototype is manufactured and tested with and without an external load. The employed load is a 4-bar linkage that emulates the behaviour of a shedding mechanism of a given weaving loom. It is found that employing a magnetic spring can effectively reduce the power consumption of the drivetrain by more than 40%. However, introducing the magnetic spring reduces the flexibility of the system. In addition, it increases the initial cost. Nevertheless, the higher initial cost of the drivetrain will be paid back by the lower energy consumption.

Metal additive manufacturing (AM) has been growing remarkably in the past few years. Thanks to the advantages of unmatched flexibility and zero material waste, this clean technology opens the door for new design solutions with greater material efficiency, which are not possible through conventional machining techniques. In this paper, we provide a technology overview of metal AM techniques that can be utilized in a wide range of applications, including constructing electrical machines. Different techniques of metal AM are discussed and compared. Additionally, the impact of the material forms (powder/wire) on printing speed and quality are studied. Based on the industrial and technical literature, this paper provides a comprehensive review of metal AM in the fabrication of electrical machines and their applications. This includes the current state of the art and associated benefits of AM in these applications.

This paper proposes a method to design an electrical variable transmission (EVT) of which the stator and inner rotor contain a distributed three-phase winding, and the outer rotor is equipped with permanent magnets and a dc-field winding. The main problem with the design of EVTs is that the modeling relies on time-consuming finite-element (FE) calculations. Studying the effect of design changes is, therefore, a cumbersome task. To minimize the need for FE calculations, scaling laws are applied, which reduce the computational effort to a matter of milliseconds per design. Therefore, the losses of multiple scaled designs can be analyzed for a given load cycle while taking constraints into account such as maximum torque. By presenting this data in a performance map, the optimal design regarding the losses is easily deduced. To validate the presented methodology, FE calculations, measurements, and available literature are used.

Although it is well known that the magnetic properties of electrical steel can be deeply affected by the cutting process, it is still not clear how to accurately evaluate these effects on a prototyped machine on its final shape, especially at a high frequency or a high power rating. This research provides a more practical method for accurate measurement of magnetic losses in electrical steel with consideration of material degradation effects due to the cutting process. Unlike other similar studies, these investigations are conducted not only on a few laminations but also on a complete electrical machine core. For a fair comparison between both cases, backlack bonding is used for lamination stacking since it is the most non-damaging joining technique. Two different test setups are used to measure the steel performance at a wide range of frequency and input power. Furthermore, a full axial length stator of a switched reluctance machine (SRM) is used as a case study to identify the magnetic properties of NO20 electrical steel. Additionally, by comparing the results obtained from the individual laminations and the assembled stator, the extra losses due to the cutting process and material degradation are extracted accurately.

description Publicationkeyboard_double_arrow_right Article , Journal 2016 BelgiumPublisher:Institute of Electrical and Electronics Engineers (IEEE) Authors: Druant, Joachim; De Belie, Frederik; Sergeant, Peter; Melkebeek, Jan;handle: 1854/LU-6972463
An electrical variable transmission (EVT) is an electromagnetic device with dual mechanical and electrical ports. In hybrid electric vehicles (HEVs), it is used to split the power to the wheels in a part coming from the combustion engine and a part exchanged with the battery. The most important feature is that the power splitting is done in an electromagnetic way. This has the advantage over mechanical power splitting devices of reduced maintenance, high efficiency, and inherent overload protection. This paper gives a conceptual framework on how the torque on both rotors of the EVT can be simultaneously controlled by using a field-oriented control (FOC) scheme. It describes an induction-machine-based EVT model in which no permanent magnets are required, based on classical machine theory. By use of a predictive current controller to track the calculated current reference values, a fast and accurate torque control can be achieved. By selecting an appropriate value for the flux coupled with the squirrel-cage interrotor, the torque can be controlled in various operating points of power split, generation, and pure electric mode. The conclusions are supported by simulations and transient finite-element calculations.

The rotor design of Synchronous Reluctance Motors (SynRMs) has a large effect on their efficiency, torque density and torque ripple. In order to achieve a good compromise between these three goals, an optimized rotor geometry is necessary. A finite element method (FEM) is a good tool for the optimization. However, the computation time is an obstacle as there are many geometrical parameters to be optimized. The flux-barrier widths and angles are the two most crucial parameters for the SynRM output torque and torque ripple. This paper proposes an easy-to-use set of parametrized equations to select appropriate values for these two rotor parameters. With these equations, the reader can design a SynRM of distributed windings with a low torque ripple and with a better average torque. The methodology is valid for a wide range of SynRMs. To check the validity of the proposed equations, the sensitivity analysis for the variation of these two parameters on the SynRM torque and torque ripple is carried out. In addition, the analysis in this paper gives insight into the behavior of the machine as a function of these two parameters. Furthermore, the torque and torque ripple of SynRMs having a rotor with three, four and five flux-barriers are compared with three literature approaches. The comparison shows that the proposed equations are effective in choosing the flux-barrier angles and widths for low torque ripple and better average torque. Experimental results have been obtained to confirm the FEM results and to validate the methodology for choosing the rotor parameters.

The goal of this paper is to evaluate additional harmonic losses in relation to the machine's initial efficiency rating. However, due to the relatively small amount of additional loss, the main drawback when evaluating the effect of supply voltage distortion on the machines' overall efficiency is the measurement accuracy of the current methods. In order to validate the effect of motor efficiency rating in relation to supply voltage distortion, the use of the parameter "harmonic active power" is suggested. This new strategy is subsequently validated by measurements and compared to current methods such as the NEMA MG1, or the procedure according to the IEC60034-2-3. Although this strategy is only valid under certain constraints, this new method enables a fast and highly accurate measurement of the additional loss. Consequently, this parameter is used to validate the effect of efficiency rating of induction motors in relation to the additional loss related supply voltage distortion.

The aim of this paper is to calculate the static eccentricity (SE) of a double rotor axial flux permanent magnet (AFPM) machine by using a general analytical model. The flux density in the air gap under healthy conditions is calculated firstly, where the axial and circumferential magnetic flux densities are obtained using a coupled solution of Maxwell’s equations and Schwarz-Christoffel (SC) mapping. The magnetic flux densities under SE conditions are calculated afterwards using a novel bilinear mapping. Some important electromagnetic parameters, e.g., back electromotive force (EMF), cogging torque and electromagnetic (EM) torque, are calculated for both SE and healthy conditions, and compared with the finite element (FE) model. As for the double rotor AFPM, SE does not contribute much effect on the back EMF and EM torque, while the cogging torque is increased. At each calculated section, FE models were built to validate the analytical model. The results show that the analytical predictions agree well with the FE results. Finally, the results of analytical model are verified via experimental results.

The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal that the additional loss due to unbalanced loading is partially dissipated in the rotor. Because analytical segregation of the individual loss components remains complex due to the skin effect in the rotor bars, Finite Element Modeling is used to accurately model the loss, inherently taking into account the skin effect. The results obtained by Finite Element Modeling are compared to practical measurements and are consequently used to evaluate the possibility of deriving lumped electrical models.

The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal that the additional loss due to unbalanced loading is partially dissipated in the rotor. Because analytical segregation of the individual loss components remains complex due to the skin effect in the rotor bars, Finite Element Modeling is used to accurately model the loss, inherently taking into account the skin effect. The results obtained by Finite Element Modeling are compared to practical measurements and are consequently used to evaluate the possibility of deriving lumped electrical models.

ESP System (ESPS) consists of several components: surface components and underground components. The surface components include an electric power supply, a transformer, a control board, and a control valve. The underground components include a centrifugal pump, an electric motor, a cable, and sensors. The existence of the components down the well exposes the system to severe challenges. The challenges that must be taken into account are several, such as depth, high temperature, high pressure, limited well diameter, corrosive surrounding material, high flow rate and high power consumption. In this paper, a comprehensive review of the ESPS is presented. It aims to provide a broad perspective on the various components of the ESPS and the trends to tackle the challenges of this type of systems.

Ibrahim; Peter Sergeant;This article compares three drivetrains for the shedding mechanism of weaving loom applications, which have a strongly oscillating load pattern. The three drivetrains employ a permanent magnet motor without a gearbox. The first drivetrain uses only the electric motor (EM1) while the other two drivetrains use the electric motor with assistance of a separate or an integrated magnetic spring (EM2MS or EMMS respectively). The magnetic spring provides part of the load torque in a passive way. This results in a reduced power consumption. The optimal design and the performance analysis of the machines have been presented for the considered application using a 2D finite element model coupled with an optimization algorithm. To validate experimentally the theoretical results, the EMMS prototype is manufactured and tested with and without an external load. The employed load is a 4-bar linkage that emulates the behaviour of a shedding mechanism of a given weaving loom. It is found that employing a magnetic spring can effectively reduce the power consumption of the drivetrain by more than 40%. However, introducing the magnetic spring reduces the flexibility of the system. In addition, it increases the initial cost. Nevertheless, the higher initial cost of the drivetrain will be paid back by the lower energy consumption.

Metal additive manufacturing (AM) has been growing remarkably in the past few years. Thanks to the advantages of unmatched flexibility and zero material waste, this clean technology opens the door for new design solutions with greater material efficiency, which are not possible through conventional machining techniques. In this paper, we provide a technology overview of metal AM techniques that can be utilized in a wide range of applications, including constructing electrical machines. Different techniques of metal AM are discussed and compared. Additionally, the impact of the material forms (powder/wire) on printing speed and quality are studied. Based on the industrial and technical literature, this paper provides a comprehensive review of metal AM in the fabrication of electrical machines and their applications. This includes the current state of the art and associated benefits of AM in these applications.

This paper proposes a method to design an electrical variable transmission (EVT) of which the stator and inner rotor contain a distributed three-phase winding, and the outer rotor is equipped with permanent magnets and a dc-field winding. The main problem with the design of EVTs is that the modeling relies on time-consuming finite-element (FE) calculations. Studying the effect of design changes is, therefore, a cumbersome task. To minimize the need for FE calculations, scaling laws are applied, which reduce the computational effort to a matter of milliseconds per design. Therefore, the losses of multiple scaled designs can be analyzed for a given load cycle while taking constraints into account such as maximum torque. By presenting this data in a performance map, the optimal design regarding the losses is easily deduced. To validate the presented methodology, FE calculations, measurements, and available literature are used.

Although it is well known that the magnetic properties of electrical steel can be deeply affected by the cutting process, it is still not clear how to accurately evaluate these effects on a prototyped machine on its final shape, especially at a high frequency or a high power rating. This research provides a more practical method for accurate measurement of magnetic losses in electrical steel with consideration of material degradation effects due to the cutting process. Unlike other similar studies, these investigations are conducted not only on a few laminations but also on a complete electrical machine core. For a fair comparison between both cases, backlack bonding is used for lamination stacking since it is the most non-damaging joining technique. Two different test setups are used to measure the steel performance at a wide range of frequency and input power. Furthermore, a full axial length stator of a switched reluctance machine (SRM) is used as a case study to identify the magnetic properties of NO20 electrical steel. Additionally, by comparing the results obtained from the individual laminations and the assembled stator, the extra losses due to the cutting process and material degradation are extracted accurately.

Although it is well known that the magnetic properties of electrical steel can be deeply affected by the cutting process, it is still not clear how to accurately evaluate these effects on a prototyped machine on its final shape, especially at a high frequency or a high power rating. This research provides a more practical method for accurate measurement of magnetic losses in electrical steel with consideration of material degradation effects due to the cutting process. Unlike other similar studies, these investigations are conducted not only on a few laminations but also on a complete electrical machine core. For a fair comparison between both cases, backlack bonding is used for lamination stacking since it is the most non-damaging joining technique. Two different test setups are used to measure the steel performance at a wide range of frequency and input power. Furthermore, a full axial length stator of a switched reluctance machine (SRM) is used as a case study to identify the magnetic properties of NO20 electrical steel. Additionally, by comparing the results obtained from the individual laminations and the assembled stator, the extra losses due to the cutting process and material degradation are extracted accurately.
