Method for recognising errors when controlling a rotating field engine |
摘要 |
The method involves forming a space pointer of an unguided electromagnetic state variable of a rotary field motor during operation of rotary field motor. The formed space pointer is analyzed on a spectral component with double frequency of the rotary field. The space pointer is closed during presence of the spectral component with double frequency on a partial winding closure in a stator winding. |
