Abstract
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.
Claims7
A rotary electric machine, comprising:
- field windings supplied with DC power;
- armature windings supplied with AC power;
- a stator core formed into a ring-like shape including slots including field slots and armature slots, the field slots housing the field windings, the armature slots housing the armature windings, the field slots and the armature slots being formed in a circumferential direction of the stator core;
- permanent magnets housed in magnet slots formed in the field slots side by side on an inner circumferential side or on an outer circumferential side of the field slots;
- and
- a rotor core opposite to the stator core, with predetermined air gap being interposed therebetween, wherein
- the permanent magnets face directly to the field windings or face to the field windings with the stator core interposed therebetween, both on the outer circumferential side and on the inner circumferential side in the field slots or the magnet slots, and
- coil ends of the armature windings straddle predetermined ones of the field slots and pass over an axial end face of the permanent magnets in the predetermined field slots.
