除铁器

The method of removing the iron can not be excited:

1. Check if the main circuit contactor is damaged and the control circuit is damaged.

2. Check if the DC main circuit insurance is burned and the safety parallel circuit breaker is working.

3. Check if the disc type iron remover is in the working position.

4. Check that the rectifier diode is intact. Use a multimeter to measure the forward and reverse resistance of each diode in turn, and compare and analyze to determine whether the diode is intact. Excitation is the device that supplies the stator power to the generator or synchronous motor stator. According to the different excitation modes of DC motor, it can be divided into his excitation, excitation, series excitation, complex excitation, etc. During the rotation of DC motor, excitation is to control the voltage of the stator to change the magnetic field and change the speed of DC motor. Changing the excitation also plays a role in changing the speed
