Abstract: A rotating electric machine includes a neutral busbar and a temperature sensor. The neutral busbar has a main body and a bent part that retains the temperature sensor therein. The main body has first and second parts each of which has one or more connection terminals formed therein. The bent part is formed between a circumferential end portion of the first part and a circumferential end portion of the second part. In the first part, there is formed, between the circumferential end portion of the first part and a closest connection terminal formed in the first part to the bent part, a first extending portion that extends axially or radially. Similarly, in the second part, there is formed, between the circumferential end portion of the second part and a closest connection terminal formed in the second part to the bent part, a second extending portion that extends axially or radially.

Abstract: A rotating electric machine includes an armature and a busbar unit. The armature includes an annular armature core and a multi-phase armature coil wound on the armature core. The busbar unit is configured to connect winding end portions of the armature coil which are arranged apart from one another in a circumferential direction of the armature. Moreover, the busbar unit is fixed to a back yoke of the armature core by a plurality of pins.

Abstract: In an armature, a busbar unit includes at least first-, second-, and third-phase busbars electrically connected to respective first-, second-, and third-phase armature windings. The first-phase busbar serves as a lowermost busbar in the axial direction, the second-phase busbar serves as an intermediate busbar stacked over the lowermost busbar in the axial direction, and the third-phase busbar serves as an uppermost busbar stacked over the intermediate busbar in the axial direction. A resin member of the busbar unit covers the lowermost busbar, intermediate busbar, and uppermost busbar stacked in the axial direction, so that the lowermost busbar, intermediate busbar, and uppermost busbar are integrated to constitute a busbar stack. A protrusion member is mounted to the intermediate busbar and protruding radially outward from the intermediate busbar. At least part of the protrusion member is located to be nonoverlapped with the uppermost busbar and the lowermost busbar.

Abstract: A starter is disclosed as having a housing carrying thereon a motor, and a pinion moving body including a pinion gear, operative to mesh with a ring gear of an engine to transfer a rotational force of the motor thereto, and a pinion shielding member connected to the pinion gear at a front end thereof. The pinion shielding member has an outer circular periphery, having an outer diameter greater than the diameter of the addendum circle of the pinion gear, and a bottomed cylindrical configuration formed with a hollow portion having a front opened end and a closed rear end. Further, a clearance between an inner circumferential periphery of the nose portion and the outer circular periphery of the pinion shielding member is minimized to avoid interference between the nose portion of the housing and the pinion shielding member.

Abstract: In a starter with which a pinion movable body with which a pinion gear and a one-way clutch were united moves on an output shaft, a holder is attached to the one-way clutch. A seal component having the shape of a ring is provided so that an end of an outer circumference of the seal component is fixed to a nose part of a housing and an end of an inner circumference of the seal component slidably contacts an outer circumferential surface of the holder. The holder is provided so that relative rotation to the one-way clutch is possible. Since the holder doesn't rotate relative to the housing, wear of a seal component is reduced compared with the case where the seal component contacts the one-way clutch which rapidly rotates whereby the sealability preventing a foreign substance or water from infiltrating into the inside of the starter can be maintained.
