  • Publication number: 20240068470
    Abstract: An electric compressor includes: a compression part; an electric motor; an inverter; a housing including a plurality of housing forming members made of metal; a seal member that has an insulation property and is provided between the housing forming members adjacent to each other; and a potential equalization member that is made of metal and is in contact with both the adjacent housing forming members to equalize potentials of the adjacent housing forming members. The adjacent housing forming members include mating surfaces, respectively. An insertion hole is formed in one of the mating surfaces of the adjacent housing forming members, at a position in which the seal member is not provided. The potential equalization member includes an insertion portion inserted into the insertion hole, and a contact portion that is a plate portion extending in a gap between the mating surfaces and is in contact with both the mating surfaces.

  • Patent number: 9003647
    Abstract: A stator structure includes: a stator core (104) having a large number of concave slots (105) and a large number of convex magnetic poles (106) circumferentially alternately arranged; and magnet wires (101) of rectangular cross section in each of which an insulating coating (103) is formed on the outer surface of a metal wire (102), wherein each of the slots (105) is formed so that the distance (W2) between both the side surfaces (109, 109) of the slot (105) gradually decreases from the bottom (107) to a distal opening (108) of the slot (105), each of the magnet wires (101) is wound around the associated magnetic pole (106) and inserted in tiers in the associated slot (105), and the magnet wire (101) is placed in the slot (105) so that the width (W1) thereof continuously or stepwise decreases from the bottom (107) to the distal opening (108) of the slot (105).
