Patent ID: 8664962

Claim:
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 1 (s) turns, and the second output winding has N 2 (s) turns, each of the N 1 (s) turns and the N 2 (s) turns being varied sinusoidally through the slots; the N 1 (s) turns of the first output winding is divided by a split ratio α into N 1 a (s) turns and N 1 b (s) turns; a lower-layer first output winding having the N 1 a (s) turns is continuously wound, as an undermost layer, around all slots; 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 1 b (s) turns is continuously wound around all slots over the second output winding; and the split ratio α is adjusted only in one or more given slots.
