Abstract:
Problem diagnostic of asynchronous motor supplied by converters is discussed in the paper. Theoretical problems of diagnostic signal chose and quality factor evaluation during normal motor operation is discussed. The proposed solution is confirmed by laboratory test of cage motor and ring motor with motor circuit nonsymmetrical.
   
Key Words: diagnostic, induction motors, voltage inverters
