The invention relates to a motor output torque control method and device, an electronic device and a storage medium. The control method comprises the steps of obtaining the current temperature of a motor and the current temperature of a motor controller, calculating the difference value between the current temperature of the motor and a preset maximum allowable working temperature of the motor toobtain the motor temperature difference, and calculating the difference value between the current temperature of the motor controller and a preset maximum allowable working temperature of the motor controller is calculated to obtain the motor controller temperature difference; obtaining the current rotating speed of the motor, and determining the corresponding current peak torque of the motor andthe current continuous torque of the motor according to the current rotating speed of the motor; determining a corresponding motor output torque limit correction coefficient according to the motor temperature difference and the motor controller temperature difference; and determining a limit boundary value of the motor output torque according to the motor output torque limit correction coefficient, the current peak torque of the motor and the current continuous torque of the motor. The control method can dynamically adapt to the driving condition of the vehicle.
