Abstract

Alternately arrange 2m stator rings in the axial direction, where m is a natural number greater than or equal to 2 (m=2 in the embodiment), each stator ring is formed with a plurality of teeth (31b-34b) and connects the teeth to each other 2m-1 slots (41, 42, 43) are formed between 2m stator rings, and the windings (36, 37, 38) in each slot (41, 42, 43) will be accommodated in the return path The windings (36, 37, 38) in the slots (41, 42, 43) at a distance of m are connected in series so that the excitation directions are opposite, so that the phases of the magnetic flux passing through the teeth (31b-34b) of each stator ring are respectively staggered by 360 ° / 2m, it is possible to abolish the winding portion (transition portion) that does not contribute to the torque, and since the magnetic circuit of each phase is shared through the return path (31a to 34a), a thin and high-output salient pole motor can be obtained, and Since the magnetic circuit of the wave winding motor is formed, the output torque can be increased compared with the salient pole concentrated winding motor.

Description

technical field

[0001] The present invention relates to a stator of a salient pole motor, which accommodates a plurality of windings wound in a plane perpendicular to the axis in a plurality of slots formed between a plurality of teeth, the plurality of teeth being aligned in the axial direction. on side-by-side configuration. Background technique

[0002] According to the following Patent Document 1, a stator of such a salient pole motor is disclosed. It has three unit stators corresponding to each of the U-phase, V-phase, and W-phase, each unit stator having two teeth spaced apart in the axial direction and a return path connecting these teeth at radially outer ends, And it is formed so that a cross section may be U-shaped. In addition, an independent magnetic circuit is formed by energizing an annular winding housed inside a unit stator having a U-shaped cross section, so that the polarity protruding from the radially inner ends of the two teeth facing the rotor Differ...
