What are the common causes of DC motor governor?

What are the common causes of DC motor governor?

1. Motor insulation is poor;

2. Loose wiring at the terminal (such as three-phase power supply, motor armature, etc.);

3. The carbon brush inside the motor is damaged;

4. The excitation coil of the motor is faulty;

5. The DC governor and motor self-tuning have not been done, and the armature current of the motor is shaken greatly after starting, which is coupled with the motor jitter phenomenon;

6. Power grid incoming voltage mutation;

7. Bad working environment, high room temperature, poor heat dissipation;

8. High humidity in the operating environment;

9. Motor reaction problems (such as encoder pulse loss, speed measuring generator damage, etc.);

10. Severe dust in the working environment, especially electrostatic dust;

11. Operating environment with acid fog or other corrosive gases.

Above is the DC governor in the use of several common explosion module reason analysis. During field commissioning, engineers should carefully analyze the field environment, motor conditions, power supply conditions and other phenomena.
