ABSTRACT:
A motor with a stator and a rotor in which the stator consists of a plurality of divided members. The motor comprises: a pair of magnetic pole cores having poles composing two mutually opposite sides of the stator and arms extending in both directions from the poles, the poles being wound with windings; and yoke cores arranged between mutually opposite arms of the magnetic pole cores formed at both ends of the yoke cores. The curved portions which are proximate to the arms of the above-mentioned magnetic pole cores are formed at both ends of the yoke cores. The dividing of the stator allows the workability to wind windings on the poles to be improved, and the blanking of the yoke cores within the width of the magnetic pole cores allows the yield of to be improved, whereby reducing the costs. A method of manufacturing the motor is also disclosed.
