FIELD: electrical engineering; electrical machines for modestic appliances, such as washing machines, refrigerator compressors. SUBSTANCE: during motor starting, starter pole coils are first to be switches on irrespective of rotor position sensor signal; then running winding is turned on according to signals coming from rotor position sensor. In case of reversal, running winding is first to be turned on irrespective of signals coming from rotor position sensor, then coils of starter poles are closed, and after that running winding is supplied with power according to inverted signals of rotor position sensor. EFFECT: improved reliability of motor starting. |
