Patent ID: 7329973

Claim:
A rotary electric machine, comprising: a stator core including a plurality of magnetic poles arranged at an interval in a circumferential direction in an inner circumferential portion of an annular yoke; windings of one or more phases wound on the plurality of magnetic poles of the stator core; a slot insulator made of an insulating resin, mounted on the stator core for providing electrical insulation between the stator core and the windings; a pair of end brackets, each attached to either of end faces of the yoke for rotatably supporting a shaft of a rotor disposed inside the stator core, the end faces of the yoke being arranged apart in an axial direction of the shaft; and a lead wire holding structure for holding two or more lead wires for external connections, with respect to the slot insulator, to which two or more lead-out wires of the windings of one or more phases are respectively connected; the lead wire holding structure including a lead wire holder made of a synthetic resin for holding the two or more lead wires in such a manner that one end of each of core wires of the lead wires is exposed and end portions of the two or more lead wires are disposed at a predetermined interval, and a holder mounting portion integrally formed with the slot insulator, onto which the lead wire holder is mounted, the holder mounting portion being arranged so that a whole or major part thereof may be located on one of the end faces of the yoke, the lead wire holder including a connection holding portion in which a plurality of connections of the core wires of the two or more lead wires and the corresponding lead-out wires are disposed at a predetermined interval so as not to contact with each other, the lead wire holder being constructed so that the connection holding portion may be located over a part of the windings and the holder mounting portion when the lead wire holder is mounted on the holder mounting portion, one of the end brackets opposing to the one end face of the yoke being formed with a recess opened toward both sides in the axial direction and opened outwardly in a radial direction of the shaft, the holder mounting portion and the lead wire holder being received within the recess when the one end bracket is attached to the one end face of the yoke.
