“…Therefore, it is very important to have the precise calculation of the losses of the IPMSM, collaborative optimization of electromagnetic and thermal design, avoid the temperature distribution in the IPMSM exceeding the maximum temperature required by the permanent magnet and winding insulation. Under the premise of ensuring the safe and reliable operation of the IPMSM, it is necessary to optimize and design the IPMSM in order to meet the requirements of fully tapping the potential of the IPMSM and making the performance of the IPMSM to the extreme [3], [4], [5].…”

An IPMSM with I2V type rotor topology structure is proposed, its loss, efficiency and torque are analyzed and compared with V and IV type. Firstly, the optimized rotor topology structures are used to analyze the no-load air-gap flux density waveform and harmonic contents of the IPMSM. The results show that the THD of the no-load air-gap flux density with the I2V type is the smallest and the sinusoidal degree of the waveform is the highest. Secondly, the loss of the IPMSM with optimized rotor topology structures are analyzed and compared. Compared with the other two rotors, the results show that the iron loss of the IPMSM with the I2V type is the smallest. The iron loss of the IPMSM with I2V type is significantly less than that of the other two rotors especially under the deep flux weakening conditions. The output torque of the IPMSM under different current angles, current densities and speed are analyzed and compared. The results show that the torque performance of the IPMSM with I2V type is better than the other two rotors. this paper proposes a simple and effective method to optimize the position and diameter of the magnetic isolation holes by establishing a parameterized model. The results show that the torque ripple and cogging torque with the further optimized I2V type rotor topology structure are greatly reduced, the iron loss and magnet loss are also effectively reduced. Finally, the von Mises stress and the total displacement of the rotor deformation of the IPMSM with the further optimized I2V type under different working conditions are verified by finite element analysis. The results show that the rotor will not rupture, the displacement is small enough to avoid the touch between stator and rotor.INDEX TERMS Interior permanent magnet synchronous motor (IPMSM), torque, iron loss, efficiency, magnetic isolation hole.

Energy saving techniques have been widely employed for traditional centralized motor drive electric vehicles (EVs) to improve the efficiency and driving range. Wheel motor drives, including in-wheel motor installed inside the wheel hub and near-wheel motor installed very close to the wheel hub can be controlled independently and accurately to provide drive and regenerative braking torque. Recently, wheel motor drive (WMD) electric vehicles (EVs) have been developing rapidly. However, only a few researchers have conducted a comprehensive survey on energy saving control methods and applications for WMD EVs. This paper presents a comprehensive review of energy saving methods and applications for EVs, as common approaches in energy saving and regenerative braking are reviewed. Then, regenerative braking in EV is presented in detail, including control strategies, simulation methods, energy storage system, case study, and efficiency and optimization methods. Moreover, the motor efficiency and motor loss efficiency optimization are discussed. Finally, the future research trends in energy efficiency saving control methods for EVs are elaborated. Therefore, this review not only provides a comprehensive analysis of recent energy saving control methods and applications for EVs but also demonstrates insights into new directions and optimizations for energy saving technologies for environmentally friendly and traffic-friendly EVs in a smart city.
