摘要： PROBLEM TO BE SOLVED: To provide a stator for rotary electric machines, wherein insulating coating will not be damaged when a stator coil is formed or attached to a slot.
SOLUTION: In portions of a stator coil 5 formed in continuous wave winding shape to be attached to slots 8, an in-slot insulating layer provided with a sheet-like insulating material 9 on a one-by-one basis is formed. In the coil end portions X-X of the stator coil 5 protruding from the slots 8, a coil-end insulating layer is formed by applying and curing liquid insulating material. Since the in-slot insulating layers are formed on the stator coil 5, formed in continuous wave winding shape in this way, the insulating layers will not be damaged, when the continuous wave winding is formed.

摘要： The permanent magnet starter motor has permanent magnets (51) located on an inner peripheral surface of a cylindrical yoke (5) with plus-side and minus-side brush elements (3) located on a disc-shaped retaining plate (4). At one end section of the yoke, on the retaining plate side, is an extended section (53) whose inner diameter is greater than the outer diameter of the retaining plate. At the end section of the yoke on the retaining plate side is a cut-out groove (54) and on the plate itself, is a radial projection (44). The retaining plate is located on the inner peripheral surface of the extended section and the projection is inserted into the groove. Hence, the positioning in the peripheral and radial directions takes place between the permanent magnets and the brush element.

The holder plate 4 is inserted into the expanded opening 53, and the yoke 5 and the plate 4 are radially aligned with each other directly. A notched groove 54 into which a bush 71 is fitted is formed in the yoke 5. The bush 71 is fitted into the notched groove 54 to determine the thrust direction positions of an external lead wire 7c, a lead terminal 7 and a lead wire 7a. A protrusion 44 is formed on the plate 4 and the width B of the protrusion 44 and the width A of the notched groove 53 are so set as to satisfy a relation A>=B. By inserting the protrusion 44 into the notched groove 54, the yoke 5 and the plate 4 are aligned with each other in a circumferential direction.
