A motor is an electromagnetic device that implements the conversion or transfer of electrical energy according to the law of electromagnetic induction.

The motor is represented by the letter M in the circuit (the old standard used D). Its main function is to generate driving torque. As a power source for electrical appliances or various machinery, the generator is represented by the letter G in the circuit. Its main The role is to use mechanical energy to convert electricity.

The reasons and processing methods for the wounding motor in the background are not turning, and the fuse is blown as follows:
1. cause of issue
①Missing a phase power supply, or connecting the fixed coil to the opposite;
② Short circuit between stator windings;
③ The stator winding is grounded;
④ The stator winding wiring is wrong;
⑤ The cross section of the fuse is too small;
⑤ The power cord is shorted or grounded.

2. Troubleshooting
① Check if one phase of the knife gate is not closed, but one phase of the power circuit is broken.
② Find the short-circuit point and repair it;
③ Eliminate grounding;
④ Misconnections are detected and corrected;
⑤ Replace the fuse;
⑤ Eliminate the ground point.
