METHOD AND STRUCTURE OF WINDING OF STATOR FOR ROTATION DETECTOR, AND ELECTRIC MOTOR COMPRISING ROTATION DETECTOR

The N1(s) turns of an output winding is divided by a split ratio α into N1a(s) turns of an output winding (1a) and N1b(s) turns of an output winding (1b). The output winding (1a) is continuously wound around all slots as the undermost layer. Output winding 2, which is different in phase by 90 degree...

Zusammenfassung:The N1(s) turns of an output winding is divided by a split ratio α into N1a(s) turns of an output winding (1a) and N1b(s) turns of an output winding (1b). The output winding (1a) is continuously wound around all slots as the undermost layer. Output winding 2, which is different in phase by 90 degrees from the output winding (1a), is continuously wound around all the slots over the output winding (1a). An output winding (1b) is continuously wound around all the slots over output winding 2. This equalizes the contribution of the output winding and output winding 2 to the flux linkage, thereby achieving high angle detection accuracy.
