The embodiment of the invention provides a motor torque control method and device, electronic equipment and a storage medium, and relates to the technical field of motor control. The method comprises the steps of obtaining a rotor rotating speed signal; processing the rotor rotation angle signal to obtain a rotor angular acceleration signal; the maximum value and the minimum value of the output torque of the motor are calculated according to the rotor angular acceleration signal; and limiting an input motor torque request based on the maximum value and the minimum value of the output torque to obtain a limited torque request, and controlling a motor based on the limited torque request. According to the method, the output torque of the motor is limited, the shaft system is effectively prevented from being damaged due to overlarge stress, and the problem that the driving shaft system or a driving half shaft is damaged due to sharp change of the wheel speed when the electric driving shaft system of the electric automobile is under a certain working condition is solved.

    本申请实施例提供一种电机扭矩控制方法、装置、电子设备及存储介质,涉及电机控制技术领域。该方法包括获取转子转速信号;对所述转子转角信号进行处理,获得转子角加速度信号;根据转子角加速度信号计算出电机输出扭矩的最大值和最小值;基于所述输出扭矩的最大值和最小值对输入的电机扭矩请求进行限制,得到受限扭矩请求,以基于所述受限扭矩请求对电机进行控制。该方法通过对电机输出扭矩进行限制,有效避免轴系应力过大而损坏,解决了电动汽车电力驱动轴系在一定工况下,存在因为轮速急剧变化而导致驱动轴系或者驱动半轴损坏的问题。
