摘要： 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 temperature detector detects the temperature of the switching element. A voltage detector detects DC voltage applied to the switching element from the battery. A control unit suspends the switching operation of the switching element when the detected temperature rises to a temperature threshold. The control unit reduces counter electromotive force generated by the electric motor. The controller changes the temperature threshold such that the temperature threshold gradually increases from when the detected DC voltage is the highest voltage in the applicable voltage range of the battery to when the detected DC voltage is the lowest voltage in the applicable voltage range.

摘要： 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. A voltage detector detects DC voltage applied to the switching element from the battery. The control unit suspends the switching operation of the switching element when the temperature detected by the temperature detector rises to a predetermined temperature threshold. The control unit also reduces counter electromotive force generated by the electric motor. 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 between the first and second temperature thresholds.

摘要： 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.
