Abstract:
1. A motor-driven compressor comprising: a compressor mechanism, disposed in a vehicle, that compresses a refrigerant; a motor mechanism that actuates the compressor mechanism, the motor mechanism including a rotatable drive shaft; a drive circuit configured to drive the motor mechanism, wherein the drive circuit is connected to a power supply so as to supply power to the motor mechanism and control a rotation speed of the motor mechanism to actuate the compressor mechanism; an inner housing that accommodates the compressor mechanism and the motor mechanism in a sealed state and holds the drive circuit; an outer housing that accommodates the inner housing so that the inner housing is disposed in the outer housing, wherein the outer housing includes a mounting portion that can be mounted to another member; an intermediate member that supports the inner housing, arranged between the inner housing and the outer housing, and including anti-vibration properties, and between the drive circuit and the outer housing, and including thermal insulation properties; and a protector that protects the drive circuit from an external impact, wherein the protector is arranged on the outer housing, wherein, one part of the motor driven compressor is configured to include the inner housing, the drive circuit, the intermediate member and the protector arranged in recited order in a radially outward direction from the drive shaft, and another part of the motor driven compressor is configured to include the inner housing, the intermediate member and the outer housing arranged in the radially outward direction from the drive shaft.
