Noise measurement of the motor on the reducer

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 standards; for multi-speed and speed-regulated motors, the rated speed shall be the maximum at the rated noise; the synchronous motor shall generally be used as the motor of the reducer at the rated voltage for the 53f reversible operation. It should be measured under the turn that produces the most noise.
