Stator flux evaluation system for rotary electrical machine - uses differential of difference winding inductances within saturation range

摘要

The stator flux evaluation system uses the differential winding inductances or the difference winding inductances of the stator winding strands within the saturation range. The obtained inductances are used to calculate the amplitude and the angle of the stator flux vector. Pref. the differentail or difference winding inductances are calculated fromt he measured conductor voltages and stator currents, the conductor voltages ubtegrated to determine the variation in the stator flux vector. USE - For indirect self-regulation of electric drive.
