The motor noise measurement on the reducer should be carried out under the no-load stable operation state; for the DC motor, the speed and voltage should be maintained at the rated value when measuring; the AC motor should maintain the power supply frequency phase supply voltage as the rated value; when the static rectification power supply is used The power supply shall comply with the relevant s

When the motor of the reducer works, it will produce a clear sound, and the greater the power, the greater the noise. * From the perspective of protecting the environment and maintaining human health, the motor noise of the reducer should be effectively controlled. At the same time, some faults of the reducer motor will be characterized in the motor noise of the reducer. Therefore, the fault diagn
