A stator of a motor is provided to facilitate assembly of separating pieces by fixing the separating pieces of a yoke unit when the yoke unit has a separating structure to minimize the loss of materials. A stator of a motor includes a yoke unit, and a plurality of teeth(120). The yoke unit is composed of a plurality of separating pieces(111) separated along the circumference, has a first coupling groove(112) and a first coupling protrusion(113) mutually coupled at the coupling surface of the separation pieces, and a fixing groove(141) and a fixing protrusion(142) mutually coupled at the inner surface of the first coupling groove(112) and the outer surface of the first coupling protrusion(113) to fix the separation pieces in line, and is formed by the compression of soft magnetic powders. The plurality of teeth(120) are placed in the yoke unit, and are wound by coils. |
