The invention belongs to the technical field of electric vehicle motor control, and particularly relates to a permanent magnet coreless hub motor for an electric vehicle and a control method. The whole motor comprises a wheel hub motor tire, a wheel hub motor, a microcontroller module, a PWM generator, a battery pack and a driving circuit. The wheel hub motor structurally comprises two outer stators, a permanent magnet, a middle rotor, a bearing, a shaft and a motor shell. The permanent magnet coreless hub motor adopts a double-stator and middle-rotor structure, and a rotor is directly connected with an automobile tire, so that the permanent magnet coreless hub motor can independently control the speeds of the tires of the left and right wheels, and in-situ turning is realized through differential control. The motor has the advantage that on the basis of normal speed regulation, the function of minimum turning radius can be realized by changing different rotating speeds of the left wheel and the right wheel.

    本发明属于电动汽车电机控制技术领域,特别是涉及一种电动汽车用永磁无铁芯轮毂电机及控制方法。整体包括轮毂电机轮胎、轮毂电机、微控制器模块、PWM发生器、电池组、驱动电路,轮毂电机结构上采用两个外侧定子、永磁体、一个中间转子、轴承、轴和电机外壳。永磁无铁芯轮毂电机采用的双定子中间转子结构,转子直接与汽车轮胎相连接,可以实现永磁无铁芯轮毂电机对左右轮轮胎速度进行独立控制,通过差速控制实现原地转弯。本发明的优点在于在正常调速的基础上还可以通过改变左右轮的转速不同从而实现转弯半径最小的功能。
