The invention discloses a motor control method, device and equipment and a computer readable storage medium, and relates to the technical field of motors, and the motor control method comprises the steps: determining an initial current working point corresponding to a target working condition of a motor on a maximum torque current ratio track corresponding to the motor; acquiring a preset target equal-torque line corresponding to the initial current working point; all alternative current working points except the initial current working point are determined on the target equal-torque line; and determining a calibration current working point of the motor under the target working condition from the alternative current working points, and controlling the motor to operate at the calibration current working point. According to the invention, the radial electromagnetic force of the motor can be suppressed to improve the NVH performance of the motor.
