Abstract:
1. A winding method of a stator for a rotation detector, the stator including a stator core that is ring shaped and has a plurality of magnetic poles, the magnetic poles being arranged at regular intervals in a circumferential direction and projecting either to an inner diameter side or an outer diameter side of the stator core, the stator core having a first output winding and a second output winding, which are different in phase by 90 degrees from each other and are wound around slots defined by the adjacent magnetic poles, wherein the first output winding has N the N a lower-layer first output winding having the N the second output winding is continuously wound around all slots over the lower-layer first output winding; an upper-layer first output winding having the N the split ratio α is adjusted only in one or more given slots.
