Abstract. Based on the comparative analysis of the performance characteristics of centralized and distributed drive electric vehicles, we found that the wheel hub motor drive mode of the electric vehicles with distributed drive have compact structure, high utilization ratio of interior vehicle space, lower center of vehicle gravity, good driving stability, easy intelligent control and many other advantages, hence in line with the new requirements for the development of drive performance of electric vehicles, and distributed drive will be the ultimate mode of electric vehicles in the future. Keywords Electric Vehicle, Drive Mode, Wheel Hub Motor, Development Analysis. ForewordCompared with conventional vehicles, electric vehicles have the advantages of high efficiency of energy conversion, low noise, zero emission, etc., and the load-carrying property and wide range speed control characteristics of motors can remove the mechanical devices such as clutch and gearbox, simplifying the structure and facilitating maintenance [1,2]. Driven by the dual pressures of energy and environment nowadays, the world's major automobile producing countries are developing electric vehicle industry with unprecedented efforts. Electric vehicles are creating a new pattern of the automobile industry, which will sure lead the main direction of the automobile industry development.As the core component of an electric vehicle, the quality of driving motor has a great influence on the power, economical efficiency and safety of the electric vehicle. However, different from other industrial motors, the motor drive system of vehicle drive motor is not only affected by the size of vehicle structure, but shall also meet the operating conditions under complex conditions [3][4][5][6]. Therefore, in addition to the requirements of high efficiency, low mass, high power density, small size, good reliability and low cost of the drive motor, it shall also adapt to the frequent start, stop, climbing, acceleration and deceleration conditions of vehicles, which require a wide range of speed and high overload factor of automotive drive motor in order to meet the performance requirements of high torque under low speed or climbing or low torque under high speed [7,8]. Drive ModeAccording to the different installation locations of drive motor in electric vehicles, there are single-motor centralized drive and multi-motor distributed drive modes. Distributed drive is further divided into wheel side motor drive and wheel hub motor drive. Centralized driveCentralized drive is close to the conventional vehicle structure, in which the internal combustion engine is replaced by a motor, and the motor torque is transmitted to the drive wheel through the power train to drive the vehicle. It can be achieved by making a slight change based on the conventional vehicle structure, which has mature, safe and reliable operation technology, but has the shortcomings of small interior size, heavy mass, low transmission efficiency and complex control.

This paper proposes a permanent magnet (PM)-assisted synchronous reluctance machine (PMASynRM) using ferrite magnets with the same power density as rareearth PM synchronous motors employed in Toyota Prius 2010. A suitable rotor structure for high torque density and high power density is discussed with respect to the demagnetization of ferrite magnets, mechanical strength and torque ripple. Some electromagnetic characteristics including torque, output power, loss and efficiency are calculated by 2-D finite element analysis (FEA). The analysis results show that a high power density and high efficiency of PMASynRM are obtained by using ferrite magnets.

-This paper proposes a demagnetization fault diagnosis method for interior permanent magnet synchronous motors(IPMSMs). In particular, a demagnetization fault is one of the most frequent electrical faults in IPMSMs. This paper proposes an estimation method for permanent magnet flux. The method is based on linear interpolation. The effectiveness of the proposed method for diagnose demagnetization faults is verified through various operating conditions by finite element simulation.
