What is the vibration of electric motors?
3, the motor is not loaded, all normal, the speed will not be obvious fast, but manned will ring or shake, belong to Holzer contact is not good, not all is just one of the line;4, the motor start normal, manned can also, but that is, the controller is started, speeding, and Holzer signal in advance commutation, this simply adjust the controller on it;
May be the following situations:1, if the idle speed is significantly faster, but not a sound or sound load personnel belongs to a phase dislocation, and the motor line (phase line) and Holzer (small line) take the wrong line;2, the motor can not start their own need to jump but have all the normal time jitter will ring manned, which belongs to the motor Que phase and three phase motor (thick line) with no electricity;
Start abnormal, a start trembling, the motor speed is slow, that is, Holzer bad, or bad contact, so that it less one Holzer work.
