Problems solved by technology

However, with the former method, there may be uneven bonding due to the varnish not spreading over the entire coil, and with the latter method, cracking may occur in the molding resin after it hardens
In these cases, it is difficult to sufficiently increase the reliability of coil fixing

Embodiment Construction

[0029] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings referred to below, the same or corresponding components will be denoted by the same reference numerals.

[0030] figure 1 is a sectional view showing the frame format of the vehicle drive unit. The vehicle drive unit shown in the figure is provided in a hybrid vehicle that utilizes an electric motor that receives electric power from a secondary battery (ie, a battery) that can be charged and discharged, as a power source, and an internal combustion engine such as a gasoline engine or a diesel engine supply.

[0031] refer to figure 1 , the vehicle drive unit has a motor generator 10 . This motor generator 10 is a rotating electrical machine that functions as a motor or a generator depending on the operating state of the hybrid vehicle. First, the basic structure of the motor generator 10 of the exemplary embodiment and a vehicle drive un...

Abstract

A motor-generator that is a rotary electric machine includes a cylindrical stator core having a plurality of teeth that are arranged spaced apart from each other in a circumferential direction and extend in a radial direction; a cassette coil arranged on an outer periphery of each of the teeth; an insulator that has a pawl portion and is interposed between the stator core and the cassette coil; and a wedge that is provided extending between the cassette coils that are adjacent to each other, which fixes the cassette coils with respect to the stator core. The wedge is retained by the pawl portions of the insulators that are adjacent to each other.

Description

[0001] incorporation by reference [0002] The disclosure of Japanese Patent Application No. 2012-282845 filed on December 26, 2012 including specification, drawings and abstract is incorporated herein by reference in its entirety. technical field [0003] BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to rotating electric machines, and more particularly, to rotating electric machines provided with a concentratedly wound cassette coil type stator. Background technique [0004] Regarding a rotating electric machine according to the related art, Japanese Patent Application Publication No. 9-84287 (JP9-84287A) describes a stator of a rotating electric machine and a manufacturing method thereof for the purpose of improving the space factor (winding density) of field windings. The stator of the rotary electric machine described in JP9-84287A includes: a stator core provided with eight pole teeth at equal intervals on an inner peripheral surface; ...
