Abstract

PURPOSE: To facilitate the work of assembly of rotary electric machine, by supplying, through an opening end side of the outer cylindrical part of the rotary machine, all of the component parts.
CONSTITUTION: An external magnetic yoke 107, including a soft, magnetic material, is provided in the inner face of a cylinder 100 forming the outer cylinder part of a rotary electric machine, and is fixed with an epoxy resin system adhesive agent used. In a front cover part 104, a projection 101 is formed and an element for housing a bearing 108 and a through hole 105 for penetrating a rotor shaft 110 are provided in the center of the projection. And inner yoke member 102 consisting of soft magnetic material and a field permanent magnet 106 are coupled in the projection. A coreless coil 119 is arranged in the space between the permanant magnet 106 and outer yoke 107, with the power supplied from a brush 113 and commutator.
