Abstract: A motor includes a stator having a core and a plurality of radially inwardly extending teeth defining slots therebetween. Each tooth has a tip having a pair of circumferentially protruding tooth projections. A first insulation sheet is inserted between each pair of the teeth and has a body part and a pair of first end parts formed by folding both ends of the body part toward each other. A second insulation sheets is arranged between the winding parts of adjacent teeth and has a body part and a pair of second end parts formed by folding both ends of the body part away from each other. The tooth projections, the second end parts and the first end parts are arranged in this order from radially inside to outside and overlap radially.

Abstract: Projections are provided on bottom surfaces of U-phase through-grooves. This configuration ensures a sufficient engagement amount of each projection with a corresponding insertion portion as compared to a case in which the projections are provided on the end of an insulator on the side opposite to a stator core. As a result, each projection is stably engaged with the corresponding insertion portion. This allows the cover to be stably attached to the insulator.

Abstract: A motor includes a rotor and a stator, the stator having a stator core and an electrical insulator assembly at each end of the stator core. The electrical insulator assemblies each have an outer wall part extending in a circumferential direction and facing a yoke of the stator core and a plurality of extending parts extending radially inward from the outer wall part and facing teeth of the stator core. The outer wall part has a radial thickness and includes a plurality of radial notches for guiding extensions of the stator winding between an inner peripheral surface and an outer peripheral surface of the outer wall part. The outer peripheral surface of the outer wall part adjacent to the notches is configured such that the radial thickness of the outer wall part gradually decreases toward the notch along a circumferential direction of the yoke.

Abstract: A motor-driven compressor includes a cluster block, which accommodates a connecting terminal. The connecting terminal connects an electric motor to a motor driving circuit. A second insulator includes a tubular base, extended portions, which extend from the base, and insulator flanges. Each insulator flange is located on an opposite end of each extended portion from the base. The cluster block is fastened to some of the insulator flanges on the opposite side of the insulator flanges from the extended portions. The cluster block includes a second wall, which faces some of the insulator flanges. The second wall includes engagement pieces, which project in the radial direction of the rotary shaft. The engagement pieces are each fitted to an opening portion, which is a gap between the insulator flanges that are adjacent to each other in the circumferential direction of the rotary shaft.
