Head objective of the paper is to create and stimulate a Novel Dual Stator Sandwiched Rotor Hybrid Magnetic Pole Six-Phase PMSG (NDSSRHMPSP-PMSG) for harnessing wind power. Wind energy is the most optimized plan for innovation since it erases the need of water and is eco-accommodating and can be a superior option for expanded energy usage. A multiphase PMSG is a superior alternative for wind energy utilization. The two-fold rotor-stator setup upgrades the machine’s voltage regulation as well as its dependability and execution. The designed NDSSRHMPSPPMSG possesses novelty in terms of its magnet structure. A Hybrid Magnetic Pole (HMP) is inserted into the rotatory portions. The concept of HMP introduces the combination of V-Shaped Magnets (VSM) and Multi-Layer Embedded Magnets (MLEM). This remarkable combination of two different magnetic formation provides a higher flux density and contributes towards an efficient operation of the proposed system. To construct the generator optimally and for evaluation, magnetostatic and transient setups are used. Because of proper examination, it may be very well presumed that the proposed novel framework is legitimate and effective.

The salient features of a Novel Dual Rotor Sandwich Stator Fusion Magnetic Pole Six Phase Permanent Magnet Synchronous Generator (NDRSSFMPSP-PMSG) for Geothermal Energy Extraction have been highlighted in the research paper. The energy retained inside the outer layer of the earth which is then transported to the surface by steam or liquids is commonly referred to as geothermal power. In Geothermal Power Plants (GPPs), synchronous generators are commonly installed. However, it seems that using a multi-phase PMSG to produce electricity from accumulated geothermal heat energy is a better alternative. The multiphase system outshines the conventional three-phase system in terms of power density, efficiency, finer torque quality, compact design, and reliability. The novelty of the machine lies in the utilization of a fusion magnetic pole which is a combination of surface mounted and hybrid delta shaped magnet. Further the use of a dual rotor-stator topology improves the power density of the machine. The Finite Element Method (FEM) is used to quantify machine parameters including the induced Electromotive Force (EMF), output strength, efficiency, total harmonic distortion (THD), and voltage regulation for the proposed generator. The analysis of the above parameters reveals that the suggested generator outperforms conventional synchronous generators and is best suited for GPPs.

Principal objective of the research paper is to develop and stimulate a Novel Dual Integrated Rotor-Stator System with Double Layered V-Shaped Magnetic Pole Six-Phase Permanent Magnet Synchronous Generator (NDIRSS-PMSG) for tidal energy extraction. The quest for generating electricity from tides using different technologies has resulted in the birth of tidal energy. While not commonly used, tidal energy has the potential to be a future source of power because it is more predictable than wind and sun. A multiphase Permanent Magnet Synchronous Generator (PMSG) is a better option for the aforementioned reason. The double rotor-stator configuration enhances the machine’s voltage regulation, as well as its stability and performance. The novelty of the designed PMSG is hidden in its magnetic pole structure. A double layered V-shaped magnet is inserted into the rotatory portions, which provides a higher flux density and contribute for a reliable operation of the proposed system. To construct the generator optimally and for evaluation, magnetostatic and transient analysis are used. As a result of the study, it can be concluded that the proposed novel system is authentic, robust and efficient.

This paper discusses the analysis of performance of a Dual Stator Dual Rotor Six-Phase I-Shaped Permanent Magnet Synchronous Motor (DSDRSPIS-PMSM) for the use of electric vehicles. This proposed motor has high performance and efficiency for the application of electric vehicles. The torque density of proposed motor is high due to the presence of dual stator in it. The two sets of 6-phase windings necessarily improve accuracy and greater potential for fault endurance of the proposed motor. The Finite Element Method (FEM) is chosen as an accurate analysis tool for the performance assessment of the proposed model. For the evaluation of results, along with magnetostatics, the transient type of analysis is also chosen. The proposed motor is analyzed to get the value of electromotive force, percentage of overall harmonic distortion, voltage-current characteristics, etc. From the aforementioned investigation, it can be inferred that, owing to magnetic-pole orientation the proposed motor is highly suitable.

This paper describes the characteristic investigation of the Novel Dual-stator V-Shape Magnetic Pole Six-Phase Permanent Magnet Synchronous Generator (NDSVSMPSP-PMSG) for wind power application. The proposed generator has V-shaped embedded magnetic pole in the rotor and six-phase winding in both the stator. The proposed generator has high-power density and high efficiency. For emphasizing the significance of the proposed generator, the characteristics of the NDSVSMPSP generator are analyzed and compared to one of the traditional generators, i.e., the Dual-stator Surface Mounted Six-Phase Permanent Magnet Synchronous Generator (DSSMSP-PMSG). For the design and characteristic investigation of both the generator, Finite Element Method (FEM) is chosen because of its high accuracy. Two modes of FEM analysis are considered, namely magneto-statics and transients. The magneto static analysis is used for the study of flux line and flux density distribution, while the transient analysis is considered for the generator’s characteristic investigation. The performance characteristics such as generated Electromotive Force (EMF) for both inner and outer stator, Percentage Total Harmonic Distortion (THD) of developed voltage, Developed EMF vs rpm, terminal voltage vs. current, developed rotor torque vs time, percent (%) ripple content in torque, and percent efficiency vs current for both generators are investigated. As a result, it can be stated that the power density and reliability of the proposed generator is higher than that of the traditional generator.
