Patent ID: 7701109

Claim:
A rotating electrical machine in which a rotor relatively rotates with respect to a stator, wherein: said rotor includes a field winding wound around a rotation shaft, and a rotor core which surrounds the field winding and which includes a rotor pawl magnetic pole at a portion of said rotor, said stator includes a stator winding which is annularly wound around an outer periphery of said rotor, and a stator core which includes stator pawl magnetic poles alternately extending from axially both sides of a portion of said stator opposed to said rotor, and which surrounds a periphery of said stator winding, wherein said stator includes a plurality of phases of said stator core and said stator winding, and connection plates made of a non-magnetic material are interposed between said plurality of phases, and wherein said stator core of each phase includes a pair of stator cores, and said stator winding of each phase is surrounded by said pair of stator cores and said stator pawl magnetic poles extending axially alternately from said pair of stator cores.
