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: An electric compressor includes a housing, an electric motor, and an inverter. The housing includes a motor chamber. The electric motor includes a stator that includes a stator core, a plurality of first coils, a plurality of second coils, and a plurality of third coils. The first coils are connected in series, the second coils are connected in series, and the third coils are connected in series. One of the first coils that is located electrically closest to the first phase is referred to as a first specific coil, one of the second coils that is located electrically closest to the second phase is referred to as a second specific coil, and one of the third coils that is located electrically closest to the third phase is referred to as a third specific coil. The first to third specific coils are disposed above the shaft center of the drive shaft.

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.
