In a stator for a dynamo-electric machine, a winding includes a conductor having a rectangular cross-sectional shape in a direction perpendicular to an axial direction, an overall shape of the conductor being a crank shape when flattened out, and the conductor includes straight portions laminated within slots, and bridge portions connecting the straight portions to each other, the bridge portions protruding from both end surfaces of the stator core in the axial direction.

Method of manufacturing dynamo-electric machine with laminated winding

Stator for a dynamo-electric machine and method for the manufacture thereof

A starter motor which comprises a housing, an electric motor having an output rotary shaft, a pinion shift cylinder driven by the output rotary shaft and having a pinion for driving an engine to be started, the pinion shift cylinder having a sliding support surface exposed to the interior of the housing. The housing supports a support bearing which has a slinding surface in engagement with the sliding support surface of the pinion shift cylinder for slidably and rotatably supporting it. The starter motor also comprises a cylindrical cover for lovering the sliding support surface of the pinion shift cylinder against any foreign matter.

Starter motor

Engine starter

A starter used to start an engine of a vehicle includes an electric motor generating rotational force. The motor has an integrally formed cup-shaped casing one end of which is open, an armature disposed within the casing, a disk (or face) type commutator supported on a rotary shaft of the armature, and brush means having brushes pressed against a brush slide contact surface of the disk type commutator and a brush supporting member made of a resin material which retains the brushes axially slidably and which is rigidly secured to the closed end wall of the casing. Since the starter employs a disk type commutator, it is possible to accommodate the brushes in the brush supporting member together with the associated springs in one unit. Accordingly, the structure is simplified and the number of required parts is reduced considerably. Thus, assembly is extremely easy.

Disk commutator starter with one-piece cup-shaped case

A coaxial type starter used to start an engine of a vehicle is disclosed. The starter comprises first and second bearings which are respectively disposed between the outer circumferential portion of a carrier of an epicyclic reduction gear which is formed integral with a clutch outer member of an overrunning clutch and a fixed portion of the starter and between the inner circumferential portion of the carrier and the outer circumferential portion of an armature rotary shaft of a d.c. motor. Accordingly, the carrier of the epicyclic reduction gear is prevented from becoming eccentric by the first bearing, and the armature rotary shaft of the d.c. motor which is supported by the carrier through the second bearing is also prevented from becoming eccentric. Thus, it is possible to eliminate any risk of the planet gears of the epicyclic reduction gear being damaged or generating noise.
