摘要： A synchronous AC motor has a stator with stator poles arranged as a plurality of circumferentially extending stator pole groups, with each stator pole group having a pair of corresponding circumferentially extending loop-configuration stator windings disposed adjacent on either side or a single such winding disposed adjacent at one side, adjacent stator pole groups being mutually circumferentially displaced by a fixed amount corresponding to a specific electrical phase angle. A rotating magnetic field is produced by applying respective polyphase AC voltages to the windings, such that currents of mutually opposite direction flow in each pair.

摘要： A rotor of an electric motor, including a rotor core having a plurality of magnet-retaining apertures, a plurality of permanent magnets individually received and retained in the magnet-retaining apertures of the rotor core, and a resinous filler filling a gap defined between each magnet-retaining aperture and each permanent magnet and fixing the permanent magnets to the magnet-retaining apertures. The rotor also includes an engaging projection provided in the rotor core, the engaging projection tightly engaged with each of the permanent magnets received in the magnet-retaining apertures and temporarily holding each permanent magnet at a predetermined position in a corresponding magnet-retaining aperture, in an unfinished state of the rotor where the resinous filler is not arranged in the gap.
