Module and device for reducing vibrating noise of motor

The utility model provides a control module for reducing the vibrating noise of a motor, and the control module comprises a unit for collecting and storing the vibrating noise data of the motor, a motor calibration parameter unit, a vibrating noise pre-compensation calculation unit, a control strategy adjustment unit (PID control algorithm adjustment unit), and a PWM control signal generation unit. In addition, the utility model also provides a device for reducing the vibrating noise of the motor, wherein the device comprises the above module. The device comprises the motor, a motor current detection unit, a motor vibrating noise detection module, the control module for reducing the vibrating noise of the motor, and a motor drive unit. The pre-compensation and the adjustment of a motor control strategy are achieved through the comparison of the measured motor vibrating noise value with a theoretical value of the motor vibrating noise, thereby reducing the motor vibrating noise. The method is simple and reliable, the cost is low, and the service life of the motor can be prolonged.
