WINDING METHOD FOR STATOR OF ROTATION DETECTOR, WINDING STRUCTURE THEREFOR, AND ELECTRIC MOTOR USING ROTATION DETECTOR |
摘要 |
The N1(s) turns of a first output winding is divided by a split ratio ± into N1a(s) turns of a lower-layer first output winding and N1b(s) of an upper-layer first output winding. The lower-layer first output winding is continuously wound around all slots as the undermost layer. A second output winding is continuously wound around all slots over the lower-layer first output winding. An upper-layer first output winding is continuously wound around all slots over the second output winding. The split ratio ± is adjusted only in the slots where the detection accuracy decreases. This equalize the contribution of the first output windings and the second output winding to the flux linkage, thereby achieving high angle detection accuracy. |
