Patent ID: 8134269

Claim:
An electric rotating machine, comprising: a rotor having plural magnetic poles along its periphery; and a stator having a plurality of teeth that are disposed opposite to the periphery of the rotor, wherein the stator includes two stator magnetic poles of a U-phase, each of which is formed by two teeth of the plurality of teeth, a first coil turn, and a second coil turn coupled in series with the first coil turn and having a polarity opposite to a polarity of the first coil turn, within a range of 360 electrical degrees subtended by the magnetic poles of the rotor, each of the first coil turn and the second coil turn is wound so as to span an electrical angle less than 180 electrical degrees in the circumferential direction, and another tooth of the plurality of teeth constituting a part of each of V-phase and W-phase stator magnetic poles is disposed between the first coil turn and the second coil turn.
