Abstract
A rotating electrical machine includes a rotor, in which a plurality of magnetic poles are provided in circumferential direction, and a stator, within which the rotor is disposed. 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 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, and, in the stator, each winding of each coil consists of an external bridge wire, a turn portion, an internal bridge wire, and a turn portion, in that order.
