Abstract:
An electric motor includes a rotor and a stator including a stator core, a plurality of armature windings, a plurality of field windings, and a plurality of bonded magnets. The stator core has a plurality of teeth alternately defining field slots and armature slots along a circumferential direction, and a stator yoke magnetically coupling the plurality of teeth opposite the rotor. Each armature winding is wound around two of the teeth sandwiched between an adjacent pair of the armature slots. Each field winding is wound around two of the teeth sandwiched between an adjacent pair of the field slots. The magnets are individually located in the field slots while opposing the field windings in the radial direction. Each adjacent pair of the magnets along the circumferential direction respectively has an adjacent pair of pole surfaces, with the adjacent pair of pole surfaces having a same polarity.
