| An inverter-integrated or an inverter-separated electric compressor has a control device. The control device estimates a compressor suction pressure based on the temperature of the power element of the inverter, or directly measures the compressor suction pressure by a sensor, or estimates the compressor suction pressure based on a compressor suction temperature or on a compressor housing temperature. Further, the control device calculates a motor torque based on a motor rotational speed, a motor phase current, and a motor phase voltage, estimates a compressor discharge pressure based on the compressor suction pressure and the motor torque, and estimates a compressor discharge temperature based on the compressor suction pressure and the compressor discharge pressure. An electric compressor having a discharge temperature detection means in place of a conventional thermal protector can be realized. | ||||||

| A control device for a hybrid compressor includes a motor driver for driving an electric motor, a clutch controller for driving an electromagnetic clutch and an engine drive timing controller. Power is transmitted from an engine to the compressor when the electromagnetic clutch is connected.

The engine drive timing controller is electrically connected to the motor driver and the clutch controller. The engine drive timing controller commands the motor driver to activate the electric motor to discharge liquid refrigerant from the compression chambers to a predetermined level so that the compressor reduces its starting torque to the second starting torque before commanding the clutch controller to connect the electromagnetic clutch to transmit the power from the engine to the compressor. | ||||||
