Abstract
The N() turns of an output winding is divided by a split ratio α into N() turns of an output winding () and N() turns of an output winding (). The output winding () is continuously wound around all slots as the undermost layer. Output winding, which is different in phase by 90 degrees from the output winding (), is continuously wound around all the slots over the output winding (). An output winding () is continuously wound around all the slots over output winding. This equalizes the contribution of the output winding and output windingto the flux linkage, thereby achieving high angle detection accuracy.
