Working principle of YEJ series motors

2018-10-28

The YEJ series electromagnetic brake three-phase asynchronous motor is composed of a dc electromagnet brake on the basis of the Y series motor.The excitation of the electromagnet is direct current, which is supplied by a transistor rectifier installed in the motor junction box. It is stipulated in JB/T6456 that the dc voltage of the motor with the center height of 112mm and above is 170V(the ac line voltage is 380V), while the dc voltage of the motor with the center height of 100mm and below is 99V(the ac y-connect voltage is 220V).

Reasons for large vibration of three-phase asynchronous motor

2018-10-28

For the wound rotor motor, the rotor winding has a fault of phase break or near phase break (the reason may be that the brush is not in contact with the collector ring or broken line; The rotor outlet line is disconnected; The end of the rotor winding and the head cover off; Poor connection between collector and slip ring, etc. The fault cause is determined by measuring the dc resistance of the rotor circuit.
