    Abstract: An on-vehicle electric compressor for a vehicle includes a compression mechanism compressing a refrigerant, an electric motor driving the compression mechanism and a housing accommodating therein the compression mechanism and the electric motor. The on-vehicle electric compressor further includes a cover fixed to the housing, a motor driving circuit disposed between the housing and the cover and driving the electric motor, and a protecting member protecting the cover against an external force caused when the vehicle has a collision. The protecting member has a contact portion that is contactable with a receiving portion when the external force is applied to the protecting member, the receiving portion having a greater rigidity than the cover to receive the external force through the contact portion.

    Abstract: An electrically-driven compressor including a housing, an electric motor, a compression mechanism, a cover member, a motor drive circuit, and a sealing member is disclosed. The electric motor is accommodated in the housing. The compression mechanism is accommodated in the housing and operated by the electric motor. The cover member is attached to the housing. The housing and the cover member form an accommodation portion including an accommodation space therein. The motor drive circuit is accommodated in the accommodation space and drives the electric motor. The sealing member is arranged between the housing and the cover member to seal the accommodation space. The sealing member includes an elastic seal portion that comes into close contact with the housing and the cover member. A core sustains the shape of the seal portion in conformance with the circumferential edge of the accommodation space. The core is formed so that at least a circumferential edge part of the core is in conformance with the circumferential edge of the accommodation space. The seal portion is formed integrally with the circumferential edge part of the shape sustaining member by depositing rubber material thereon.

    Abstract: A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A control unit controls the switching operation of the switching element. A temperature detector detects the temperature of the switching element. The control unit suspends the switching operation of the switching element when the temperature detected by the temperature detector rises to a temperature threshold. The temperature threshold includes a first temperature threshold, corresponding to a withstand temperature of the switching element, and a second temperature threshold, which is higher than the first temperature threshold. The control unit switches the temperature threshold from the first temperature threshold to the second temperature threshold when the control unit activates a field weakening control that reduces counter electromotive force generated by the electric motor.

    Abstract: An electric compressor has a hermetic terminal unit that is electrically connected to a motor side wire and a drive circuit side wire and inserted through a through hole formed through a separation wall separating a motor chamber and an accommodating chamber. The hermetic terminal unit has a first connecting terminal that is electrically connected to the motor side wire and elastically deformable, a second connecting terminal that is electrically connected to the drive circuit side wire and elastically deformable, and a conductive member that is fitted to the first connecting terminal and the second connecting terminal and electrically connects the first connecting terminal and the second connecting terminal. The first connecting terminal is elastically deformed and holds the motor side wire by a restoring force thereof. The second connecting terminal is elastically deformed and holds the drive circuit side wire by a restoring force thereof.

    Abstract: A motor-driven compressor includes a metal housing accommodating a compression unit and an electric motor and a cover coupled to the housing. The cover and the housing define an accommodation chamber that accommodates a motor driving circuit that drives the electric motor. The cover includes a metal shield that blocks electromagnetic noise, a resin outer insulator that is fixed to an outer side of the shield and includes an outer circumferential portion, and a resin inner insulator that is fixed to an inner side of the shield and includes an outer circumferential portion. The shield, the outer insulator, and the inner insulator are separate from one another and stacked together. The shield is held between the outer insulator and the inner insulator. The outer circumferential portion of the outer insulator is joined to the outer circumferential portion of the inner insulator.
