Benefits of technology

[0096] According to this arrangement, the connector base portion is attached beforehand to the resin molding plate portion of the bus-bar assembly. This eases taking out the power terminals. Furthermore, the communication or control connector is fixed to the resin molding plate portion of the bus-bar assembly. The total number of components is small. The connecting work is simple. The communication control connector and the power connector can use the same connector base portion. Preferably, the

Problems solved by technology

It is hence difficult to replace the conventional belt-driven compressor by the above-described inverter-integrated motor-driven compressor.
The processes and the costs will increase.
Furthermore, the engine room capacity or volume available for the devices associated with the engine tends to decrease.
It was however difficult to cool the inverter section when it is placed adjacent to the motor section.
However, it is not easy to e

Abstract

A bus-bar integrated plate and outer frame section, arranged into a double-deck structure and having numerous bus bars molded with a resin molding plate portion, is provided as a wiring for connecting power switching elements and a smoothing capacitor, fixed on an outer surface of a cylindrical wall of a motor housing, to a printed circuit board serving as a control circuit.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an inverter-integrated motor for an automotive vehicle, and more particularly relates to the improvement of its inverter section. [0003] 2. Description of the Background Art [0004] To maintain the condition of an air-conditioning system when an engine is temporarily stopped during a short period of time (e.g., during a so-called “idling stop” operation), it is conventionally known that a motor-driven compressor is preferably employed for a refrigerating cycle system of an automotive vehicle. Furthermore, it is conventionally known that a motor section of the motor-driven compressor is cooled by a low-pressure coolant gas. [0005] Furthermore, there is a conventional motor-driven compressor having an inverter section mounted thereon, which is already proposed for automotive vehicles. The inverter section is equipped for driving an alternating-current motor under supply of direct-curren...
