The invention relates to the technical field of vehicles, in particular to an electric drive assembly for a vehicle, a control method of the electric drive assembly and the vehicle, and aims to solve the problem that an existing electric drive assembly cannot reasonably monitor the temperature of a motor rotor. The electric drive assembly for the vehicle comprises a motor shaft, a motor rotor, a motor end cover and a motor shell, the motor rotor is installed on the motor shaft, the motor shaft is installed in the motor shell in a pivoted mode, the motor end cover covers the motor shell, the electric drive assembly further comprises an eddy current stator, the eddy current stator is installed on the inner side wall of the motor end cover, and the eddy current stator is installed on the inner side wall of the motor end cover. The eddy current stator is provided with a temperature sensor, and the temperature sensor is used for obtaining the temperature of the motor rotor and is in communication connection with a controller of the electric drive assembly. The temperature sensor is arranged on the eddy current stator to obtain the temperature of the motor rotor, the motor is controlled based on the obtained temperature of the motor rotor, and magnetic steel demagnetization and bearing damage caused by temperature rise of the rotor are avoided while high-speed operation of the rotor is met.

    本发明涉及车辆技术领域,具体提供一种用于车辆的电驱总成及其控制方法以及车辆,旨在解决现有电驱总成无法对电机转子的温度进行合理监测的问题。为此本发明的用于车辆的电驱总成包括电机轴、电机转子、电机端盖和电机壳体,电机转子安装于电机轴上,电机轴枢转安装于电机壳体内,电机端盖盖设于电机壳体上,电驱总成还包括电涡流定子,电涡流定子安装于电机端盖的内侧壁上,电涡流定子上安装有温度传感器,温度传感器用于获取电机转子的温度并且与电驱总成的控制器通信连接。通过在电涡流定子上设置温度传感器来获取电机转子的温度,基于获取的电机转子的温度对电机进行控制,在满足转子高速运转的同时避免其温度升高后导致磁钢退磁、轴承损坏。
