Abstract: A stator of a rotating electric machine includes: a stator core including a yoke; an insulator having a plurality of insulator inner walls; a cover; a first insulating member; and a second insulating member. The cover has an insertion plate extending in an axial direction of the yoke. The insertion plate has a support surface that is located in a space between the insulator inner walls adjacent to each other in a circumferential direction of the yoke and located inward of the second insulating member to support the second insulating member in a radial direction of the yoke. The support surface is located outward of a slot opening in the radial direction of the yoke when viewed in the axial direction of the yoke.

Abstract: The cluster block accommodates connection terminals and has conductive member insertion holes, into which the conductive members are inserted. The cluster block is disposed between the bottom wall of the housing and second coil ends. The conductive member insertion holes are located on the radially outer side of the inner circumferential surface of the stator core. The cluster block includes a second wall portion in the vicinity of the electric motor and a first wall in the vicinity of the bottom wall of the housing. The second wall portion has a pressed surface on the radially inner side of the inner circumferential surface of the stator core. The outer surface of the first wall portion has a contact surface that is lined up with the pressed surface in the axial direction of the stator core. The contact surface is allowed to contact the bottom wall of the housing.

Abstract: A permanent magnet embedded type rotating electrical machine includes a rotor and a stator. The rotor includes a rotor core formed by a plurality of stacked and laminated magnetic steel plates and permanent magnets. Each magnetic steel plate has a plurality of magnet holes, connecting portions and sectional areas. The sectional area is surrounded by lines extending between the opposite ends of the magnet hole and between a rotation center of the rotor and the respective ends of the magnet hole. The connecting portion is provided only inside of the sectional area and is a joining portion at which any two adjacent magnetic steel plates are joined or a fastening hole in which a fastening member is inserted. The connecting portions include both the joining portion and the fastening hole. The connecting portion provided in the sectional area is at least one of the joining portion and the fastening hole.

Abstract: A motor-driven compressor includes a plurality of motor wires and an insulating terminal container. The motor wires include portions covered with an insulating tube and distal ends at which a connection terminal is provided. The terminal container includes a cluster block and a terminal holder. The cluster block accommodates the connection terminal and has an opening. The terminal holder holds the connection terminal and has a lid that closes the opening. The cluster block includes a base portion. The lid has a cutout that receives the tube. The lid is in contact with the base portion such that a part of a hole defined by the cutout is closed by the base portion.

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.

Abstract: A motor-driven fluid machine has three motor wires. The innermost one of the three motor wires in the radial direction of a rotary shaft on a specific section of an outer end portion of a coil end is defined as a first motor wire. The first motor wire has a first extension, which extends from an inner side toward an outer side in the radial direction of the rotary shaft at a position between the specific section and a downstream side in the extending direction of the motor wires, and a second extension, which is continuous from the first extension and extends from the outer side toward the inner side in the radial direction of the rotary shaft to be connected to a corresponding conductive member.
