A mechano-electrical integrated power conversion device includes power drive unit and voltage converter that are housed within a single housing box and formed as a module. The box includes box body, upper lid member, and side lid member. The box body includes: a box body main portion disposed above a casing of an electric motor; and a box body remainder portion connected integrally to a side wall of the box body main portion and extending downwardly to a side of the casing. The upper lid member is mounted on the box body main portion, a first housing chamber being defined therebetween and housing the power drive unit. The side lid member is mounted on a side open end part of the box body remainder portion, a second housing chamber being defined between the box body remainder portion and the side lid member and housing the voltage converter.

Mechano-electrical integrated power conversion device and drive device for electric automobile

A support plate is accommodated in the interior of a casing, the support plate having a bearing member that rotatably supports a rotating shaft of a brushless motor, together with supporting a circuit substrate on which a control circuit is provided. The casing is constituted by combining a lower side half body and an upper side half body. A second flow passage through which cooling air (air) is allowed to flow is formed in the lower side half body, and a protrusion is provided therein, which serves as a guide member for guiding the cooling air toward the side of (a first flow passage of) the upper side half body.

Blower motor unit for air conditioner

A stator of a brushless motor is provided with stator side terminal portions. A circuit board is provided with board side terminal portions. The stator side terminal portions are connected to adjacent two of U phase electromagnetic coils, V phase electromagnetic coils and W phase electromagnetic coils. The stator side terminal portions and the board side terminal portions are electrically connected via flexible wires.

Air-conditioning blower motor unit

Provided is an air-conditioning blower motor unit that includes: a brushless motor which has an output shaft to be coupled with an air-conditioning blower fan constituting an air conditioner; a circuit board configured to allow the brushless motor to be driven by a supply of electric power; a casing configured to house the brushless motor and the circuit board; and a base frame configured to support the circuit board and the output shaft. The circuit board on the base frame is disposed at a position eccentric with respect to the output shaft inside the casing.

A power supply control apparatus includes: a control board that is configured to control a voltage of a battery module; and a bus bar module that is configured to electrically connect the control board to the battery module, the control board and the bus bar module are arranged in a stacked manner, and the bus bar module includes a plurality of bus bars that are made to be independent by cutting off junctions connecting the bus bars to each other and a resin member that supports the bas bars in a state where the junctions are exposed.

Power supply control apparatus and manufacturing method of power supply control apparatus

A power supply control device includes: a control board that is configured to control a voltage of a battery module; and a bus bar module that is configured to electrically connect the control board and the battery module, the control board and the bus bar module are arranged in a stacked manner, and connection terminals of the bus bar module which are connected to the battery module are exposed when viewed from the control board.
