Electrical Vehicles (EVs) are regarded as an effective solution in a world where environmental protection along with energy crises is gaining higher attention. Permanent Magnet Synchronous Machines (PMSMs) are considered significant competitors for EVs amongst the other varied motor drives. Owing to their higher efficiency, higher output power to volume ratio, and higher torque to current ratio, they are regarded as a feasible option in several sorts of applications like wind turbines, along with EVs. For higher-performance applications, Permanent Magnet (PM) motors with Rare-Earth (RE) magnets are pondered as one of the best candidates. Conversely, replacing the Rare-Earth (Neodymium-iron-boron) in EVs with lesser or even no RE alternatives is the most critical concern in PM owing to their limited along with the unstable supply of RE elements. Therefore, to eliminate the usage of RE magnets as well as to identify the finest alternative materials, which assure lower cost along with mass production in manufacturing industries, various permanent magnetic materials are examined here with different PMSM designs for EVs applications. Manganese Aluminide (MnAl), Ferrite, Tetrataenite (L10FeNi), Iron Nitride (Fe16N2) and Nanocomposite magnetic materials are the varied magnetic materials utilized for evaluation. For varied magnetic materials, the simulation outcomes are obtained regarding the variations in cogging torque, average torque, efficiency, along with magnet mass. On analogizing RE with various magnetic materials, it was established that a higher performance was attained by replacing RE magnets with substitute magnetic material; in addition, it also proves to be highly effective. It is observed that although their electromagnetic performance of the various materials is similar, iron nitrade has an excellent demagnetization withstand capability. Finally, in contrast to the interior V type with rare earth magnets, iron nitrade and MnAl magnet machine can attain better torque development with high efficiency.

“…Permanent magnet synchronous motors (PMSMs) have been widely applied in household appliances, new energy power generation, electric vehicles, aerospace industry, and other fields [1][2][3], because they offer significant advantages such as high efficiency, high torque-to-volume ratio, and high power factor [4,5]. Especially in the field of automobiles, pure electric vehicles (EV) gradually replace traditional fuel vehicles due to their significant advantages of high efficiency and zero-emission [6]. However, the air-gap magnetic field of conventional PMSM is difficult to regulate, which limits its speed range [7].…”

In this paper, a novel mechanical-flux-weakening interior permanent magnet (MFW-IPM) machine is proposed to improve flux-weakening ability. The key of the proposed machine is that the permanent magnet is rotatable, and a mechanical device is equipped on both sides of the rotor. The mechanical device can regulate the air-gap magnetic field by rotating PM to change the leakage flux and magnetization direction of PM. As a result, the flux-weakening ability is improved. The flux-weakening principle of the MFW-IPM machine is investigated in detail. In addition, a multi-objective optimization method is adopted to improve the performance of the proposed machine. Then, the electromagnetic performances of the original machine and optimized machine are compared by finite element analysis. Finally, both simulation results and experimental tests verify the effectiveness of the flux-weakening enhancement design and optimization method.
