Embodiment Construction

[0014] Refer below Figure 1A , Figure 1B with figure 2 An electric scroll compressor 10 according to one embodiment of the present invention is described. In the following description, the front-back direction is defined as Figure 1A In the direction of the arrow Y1. The up-down direction is defined as Figure 1A In the direction of the arrow Y2. Likewise, the left-right direction is defined as Figure 1B in the direction of the arrow Y3.

[0015] Such as Figure 1A with Figure 1B As shown, a mounting portion 13 for fixing the electric compressor 10 to the base 12 is formed on the casing 11 of the electric compressor 10 . In this embodiment, the housing 11 and the mounting portion 13 constitute a body KT of the electric compressor 10 . The base 12 is an inner wall surface of a drive source chamber that accommodates a motor as a drive source for vehicle running in, for example, a hybrid car or an electric car. The mounting portion 13 is fixed by a fastener such as a...

Abstract

A motor-driven compressor includes an electric motor (23), a compression mechanism (32), which compresses gas by being driven by the electric motor (23), and a body (KT) accommodating the electric motor (23) and the compression mechanism (32). The motor-driven compressor includes a motor control section (51), which drives the electric motor (23) by controlling power supply to the electric motor (23), a vibration control section (52), which generates a waveform in a phase opposite to the waveform of vibration predicted to be generated in the body (KT) due to the driving of the electric motor (23), and a vibration applying device (45a-45c), which is located on the body (KT) and applies vibration in the opposite phase generated by the vibration control section (52) to the body (KT).

Description

technical field [0001] The invention relates to an electric compressor capable of reducing driving noise. Background technique [0002] In a related art hybrid vehicle or an electric vehicle that installs an electric motor as a driving source for propelling the vehicle, noise due to electric motor driving is reduced by making the electric motor inactive when the vehicle is parked temporarily. In a vehicle such as a hybrid car, an electric compressor is installed so that the air conditioner can be used regardless of the driving state of the electric motor for propulsion. [0003] However, if the electric compressor is mounted on a vehicle such as a hybrid car, since the electric compressor is driven when an electric motor for propelling the vehicle is not in operation, noise may become a problem. Regarding this problem, a noise reduction device for canceling the driving noise of the compressor has been proposed, see Japanese Laid-Open Patent Publication: No. 4-334713. [00...
