Fault phenomenon: It can be started. After successful start, the frequency is much higher than the original, and sometimes it is not easy to start.

Fault analysis and treatment: This is mostly a load problem.

A. There is a short circuit between turns of the load coil, which may overlap between wires or have conductive iron filings, copper wires, etc.
