The invention relates to a fatigue damage monitoring method and device of a motor, a vehicle and a storage medium, and relates to the technical field of motors, and the method comprises the steps: obtaining a rotating speed signal of the motor; determining accumulated damage of the motor based on the rotating speed signal; and determining that the accumulated damage meets a preset condition, reducing the maximum rotating speed of the motor, and controlling the motor to work within the reduced maximum rotating speed. When it is determined that the accumulated damage meets the preset condition, the failure risk of the motor can be reduced to a certain extent by reducing the maximum rotating speed of the motor.
