PROBLEM TO BE SOLVED: To easily wind a stator winding, to enhance an occupied ratio in a stator core, to reduce winding resistance due to no coil end, and to change field magnetic flux according to usage. SOLUTION: In the stator core, stator core pawl magnetic poles extend from both sides in an axial direction alternately at locations opposed to a rotor to form a plurality of magnetic poles. By using this stator core, it is only necessary to annularly wind a stator winding. Thus, operability and an occupied ratio can be improved, and since there is no coil end, winding resistance can be reduced. Since the rotor is a Randall type rotor having a field winding and a rotor pawl magnetic pole, the field magnetic flux can be changed according to usage. COPYRIGHT: (C)2008,JPO&INPIT
