摘要： The present invention provides a motor which includes a stator including a plurality of one-phase stators composed of a pair of stator cores having claw-type teeth and a coil for generating magnetic flux at the claw-type teeth, and a rotor for generating torque at a rotary shaft, wherein the stator core includes a plurality of split cores having the same shape, and the split cores are formed to have a recessed portion and a projected portion to be fitted in the recessed portion. Thereby, by using a plurality of the split cores having the same shape, one stator core is formed. On this occasion, the shape of the split cores is molded so that the recessed portion and the projected portion of one stator core are disposed at positions at which those are fitted to the projected portion and the recessed portion of the opposing stator core, respectively.

摘要： In a motor having a pawl-shaped magnetic pole, if a coil is wound like a ring shape so as to be formed, one leader line can be generally drawn out to an external portion from a position close to an outer periphery of a stator, however, the other leader line is drawn out to the external portion from an inner periphery of the stator. Accordingly, the leader line occupies a part of the inner space formed by the stator core, so that there is generated a problem that a space factor of the coil is reduced. Accordingly, an object of the present invention is to improve the space factor of the coil. In order to achieve the object mentioned above, a space passing wirings of a plurality of coils therethrough is provided in a part of the pawl-shaped magnetic pole of the stator core of the stator having the pawl-shaped magnetic pole. Accordingly, one of leader lines of the coil is drawn out from an outer peripheral portion (or an opposite side to a side facing to the rotor) of the stator, and the other is drawn out in an axial direction from the space of the claw-shaped magnetic pole of the stator. Therefore, it is possible to do away with an influence by the leader line, it is possible to increase a winding number of the coil even in the same space, and it is possible to improve a downsizing of the motor.
