Motor with stator configuration for increased coil length and coil space factors
Abstract:
A motor including a stator and rotor. The stator includes a stator core, slot portions and coils. The stator core includes stator core pieces with teeth portion having a distal end portion and two side portions, a yoke portion, and a claw portion formed at one of the two side portions. At the distal end portion, the stator core pieces are connected so that claw portions protrude in the same circumferential direction to form the stator core into a cylindrical shape. The slot portions are formed between adjacent teeth portions and between the stator core pieces. The coils form three phases which are inserted into the slot portions, are bridged between two of the slot portions and include end portions that protrude from an edge face of the stator core in an axial direction. The coils are arranged so that the end portions are intersected with each other.
