The excitation is not normal, and the motor will drop the chain in minutes.

The resultant magnetic flux is generated by the synthetic magnetic potential of all windings of the motor. In the traditional DC motor, the effective magnetic potential is mostly produced by the excitation windings; in the transformer, the net excitation is provided by the primary or two side windings, or each part is provided, and the AC motor is similar.


Providing excitation for AC motors will have an important impact on the operation economy and reliability of motor applications.

The normal operation of excitation system is a prerequisite for ensuring the normal operation of the motor.
