Stator for rotary electric machine

摘要

The invention relates to a stator for an axial gap type rotary electric machine which is opposed to a rotor in a direction of an axis of a rotating shaft, comprising an annular first stator having a plurality of first teeth and an annular second stator having a plurality of second teeth opposed to the first teeth in the direction of the axis, the second stator being rotatable about the axis, wherein a coil is wound around each of the first teeth. The first stator has a contacted surface with which the second stator is in direct or indirect contact, regulating a distance in the direction of the axis between a surface of the first stator in which the first teeth are buried, and a surface of the second stator in which the second teeth are buried. The invention also relates to a stator for a radial gap machine.
