  • Publication number: 20200313495
    Abstract: An electric compressor includes a cylindrical motor housing, an inverter case, and a conductive member. The inverter case is joined to an end portion of the motor housing. The inverter case includes a cylindrical case peripheral wall surrounding the end portion. The end portion has an end face that extends in a radial direction of the motor housing and a peripheral surface that extends in an axial direction of the motor housing and is connected to the end face. A ring-shaped sealing member is disposed between the peripheral surface and the case peripheral wall. An accommodation groove for accommodating the sealing member is recessed in the peripheral surface. The sealing member is held by the peripheral surface and the case peripheral wall in a radial direction of the sealing member to seal a space in which the conductive member is disposed.

  • Publication number: 20200313504
    Abstract: Connectors are each integrated with a holder in a state in which bus bars are projected. A first projection and a second projection of the holder are respectively inserted in a first insertion hole and a second insertion hole in a circuit substrate. This determines positions of the holder and the circuit substrate relative to each other. The holder has coil lead wire insertion holes, capacitor lead wire insertion holes, and element lead wire insertion holes. These insertion holes extend in the same direction as the direction in which the bus bars project from the holder.

  • Patent number: 10680448
    Abstract: A voltage detection circuit detects the voltage of a plurality of serially connected cells in a power storage unit. The voltage detection circuit receives a supply of a power supply voltage from both ends of the plurality of cells. A DC-DC converter converts the voltage between both ends of the plurality of cells into another DC voltage. An adjustment circuit adjusts the power consumption of the plurality of cells. The adjustment circuit operates using the DC voltage generated by the DC-DC converter as the power supply voltage.

  • Patent number: 10677262
    Abstract: A motor-driven compressor includes collars, which maintain the gap between a cover and an outer surface of a first housing member. Fasteners fasten the cover to the first housing member. Each collar is arranged to face a seating surface of the head of the corresponding fastener such that the cover is sandwiched between the collars and the seating surfaces. Each collar thus includes a facing portion, which faces the seating surface and receives a pressing force from the seating surface via the cover, and a transmitting portion, which transmits the pressing force received at the facing portion to a base member. Accordingly, the pressing force applied through the seating surface of the fastener is transmitted to the base member through the collar, so that the base member is pressed against the outer surface of the first housing member.

  • Patent number: 9995302
    Abstract: A motor-driven compressor includes an electric motor, a drive circuit, a modulation method controller, a temperature measuring section, a high-temperature (HT) stop controller, and a high-temperature (HT) stop temperature setting section. The high-temperature (HT) stop controller stops the electric motor when the temperature measured by the temperature measuring section is higher than or equal to a predetermined high-temperature (HT) stop temperature. When the modulation method is the three-phase modulation, the HT stop temperature setting section sets the HT stop temperature to a three-phase high-temperature (HT) stop temperature. When the modulation method is the two-phase modulation, the HT stop temperature setting section sets the HT stop temperature to a two-phase high-temperature (HT) stop temperature, which is higher than the three-phase HT stop temperature.
