1. Single-phase start: Check the power cord, motor lead-out line, fuse, switch contacts, and find out after the disconnection or false connection fault.
2. Set, rotor winding grounded or shorted: correct the error.
3. The motor load is too large or stuck: adjust the load to the rated value and eliminate the failure of the driven mechanism.
4. The cross-sectional area of ​​the solution is too small: the melt does not protect the motor from overloading. Generally, the melt should be selected according to the following formula. The rated current of the melt = the blocking current of /2 to 3.
5. The starting resistance of the wound rotor motor is too small or shorted: eliminate short circuit fault or increase starting resistance.
6. Short-circuit the connection between the power supply and the motor: Repair the short-circuit point.
