摘要： A stator core and a rotor core are provided. The stator core includes field windings receiving a direct current, and armature windings receiving an alternating current. Permanent magnets, each housed in one of the slots together with ones of the field windings, and in contact with the ones of the field windings, are provided. The field windings are provided on both of inner and outer circumferential sides of the permanent magnets.

摘要： A stator core including field slots housing field windings and armature slots housing armature windings is provided. Permanent magnets are housed in the respective armature slots. The armature windings are configured by a first winding and at least one second winding. The field winding passes over the permanent magnet. The second windings each have a part embedded between a coil end of the field winding and teeth around which the field winding is around.

摘要： 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.

摘要： A stator core including field slots housing field windings and armature slots housing armature windings is provided. Permanent magnets are housed in the respective armature slots. Field windings face to the permanent magnets directly or via the stator core on the outer and inner circumferential sides. A coil end of one of the armature windings straddles the predetermined one of the field slots and passes over the axial end face of each of the permanent magnets in the corresponding one of the field slots over which the coil end straddles.
