The motor is often damaged due to improper operation, which not only loses money, but also has a great impact on the production schedule. Therefore, the correct use of the frequency converter has a positive effect on protecting the motor. Eneng Electric summarized the protection of the motor by the inverter in the motor as follows:
 
1. Over voltage protection
 
2. Under voltage protection
 
3. Over current protection
 
4. Phase-loss protection
 
5. Underload protection
 
6. Overload protection
