ABSTRACT:
A dynamo-electric machine comprises a stator having a stator core formed with 9 slots and a first 3-phase stator coil and a second 3-phase stator coil inserted into the slots, and a rotor disposed inside the stator for forming 8 magnetic poles, the first 3-phase stator coil and the second 3-phase stator coil each comprising a U-phase coil portion, a V-phase coil portion, and a W-phase coil portion, each formed by winding wire onto teeth, wherein each of the phase coil portions of the first 3-phase stator coil and the phase coil portions of the second 3-phase stator coil corresponding to the phase coil portions are positioned so as to be offset from one another by a distance of one tooth in the circumferential direction.
