Patent ID: 8471428

Claim:
A rotating electrical machine comprising: a rotor in which a plurality of magnetic poles are provided in a circumferential direction, and a stator within which the rotor is disposed with a gap against the stator, wherein in the stator, two stator magnetic poles are formed by winding coils of one phase and by a stator core of the stator, within 360° of electrical angle defined by the magnetic poles of the rotor, the coils that form respective stator magnetic poles have angular widths in the circumferential direction of less than 180° of electrical angle, the coils that form the respective two stator magnetic poles are provided so as not to mutually overlap and are wound so that adjacent ones of the stator magnetic poles have mutually opposite polarities, a plurality of coils of one phase, including a first coil, a second coil, and a third coil, are formed with one conducting wire, and only at a coil end portion at one side of the stator, an external bridge wire connecting the first coil and the second coil extends from an inner circumferential side of a slot of the stator relative to a turn portion of the first coil to an outer circumferential side of a slot of the stator relative to a turn portion of the second coil, and an internal bridge wire connecting the second coil and the third coil extends from an outer circumferential side of a slot of the stator relative to a turn portion of the second coil to an inner circumferential side of a slot of the stator relative to a turn portion of the third coil.
