Patent ID: 8604804

Claim:
A winding method of a stator for 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 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 the slots; the second output winding is continuously wound around all the slots over the lower-layer first output winding; and an upper-layer first output winding having the N 1 b (s) turns is continuously wound around all the slots over the second output winding.
