Abstract
In an electric compressor integrally comprising a compression mechanism, a motor and an electric circuit (inverter) for driving the motor, the electric circuit is protected from thermal damage. When an actual number of revolutions is not more than a fixed number of revolutions and the temperature of an electric circuitexceeds a fixed temperature, the temperature Tm of a motorand the temperature Ti of the electric circuitare lowered by increasing the number of revolutions of the motor, and when the actual number of revolutions is more than a fixed number of revolutions and the temperature of the electric circuitexceeds a fixed temperature, the temperature Tm of the motorand the temperature Ti of the electric circuitare lowered by decreasing the number of revolutions of the motor.
