Abstract
A stator and a method of manufacturing the same for facilitating a winding step of armature windings and reducing cogging torque. A segment partradially having a plurality of teethA and joined arcuately at one end is punched out from an oriented electromagnetic steel sheetsuch segment partsare circularly connected, the circularly connected segment partsare stacked thereby forming a tooth partarmature windingis wound from the other end of the toothA, and the tooth partis fitted into a circular yoke parthaving a plurality of recessesat the inner circumference and stacked in the axial direction of the motor.
