Problems solved by technology

In this positioning structure, when a force is applied to the stator hoop support when bending to form the stator coil, stress concentrates on the inner annular portion having a thin (small) width, which causes breakage
For this reason, it is conceivable to provide positioning protrusions on the outer annular portion having a wide radial length (width) and disposed on the outer peripheral side, but if a positioning protrusion having an irregular shape is formed in the annular outer annular portion protruding part, it will distort when using the

Embodiment Construction

[0023] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The shapes, materials, numbers, etc. described below are examples for explanation, and can be appropriately changed according to the specifications of a support for a stator or a stator of a rotary electric machine. In the following description, the same reference numerals are assigned to similar constituent parts. Note that a rotary electric machine stator including a bracket for the stator constitutes a rotary electric machine in combination with a rotor fixed to a rotary shaft. The rotary electric machine is used as a motor or a generator, or a motor-generator having both the functions of a motor and a generator.

[0024] figure 1 is a perspective view showing a part in the circumferential direction of the rotary electric machine stator 10 including the stator hoop support 20 according to the present embodiment. Hereinafter, the rotary electric machi...

Abstract

A supporter for a stator is put on an axial end surface of a stator core of a motor. The supporter includes an outer annular portion, an inner annular portion, supporter teeth, a projection. The supporter teeth are placed between the outer annular portion and the inner annular portions. The supporter teeth are extending radially around a rotation axis of the motor, and configured to connect the outer annular portion to the inner annular portions. The projection is provided on a radially outer peripheral surface of the outer annular portion so as to project radially outwardly. The projection is an axial thickness smaller than an axial thickness of the outer annular portion.

Description

technical field [0001] The invention relates to a carrier for a stator which is arranged on an axial end face of a stator core. Background technique [0002] Typically, stator coils are wound around stator teeth of a stator core, thereby constituting a rotary electric machine. Here, in order to improve the workability of the winding operation of the stator coil to the stator teeth, a bracket made of resin may be placed on the axial end surface of the stator core. This support is referred to as a "cuff support". [0003] Japanese Patent Application Publication No. 2007-312549 (JP 2007-312549A) describes a stator of a rotary electric machine in which a stator hoop support is placed on an axial end surface of a stator core. The stator hoop support is configured to include an outer annular portion, an inner annular portion, and a plurality of hoops arranged between the outer annular portion and the inner annular portion to radially connect the outer annular portion and the inn...
