Abstract
This electric compressor includes a compressor which rotates to compress a fluid, a motor which rotatably drives the compressor, and a control unit which controls current supply to the motor using first and second components. An allowable current for first and second components exposed to the same temperature is set to be smaller in the second component than in the first component. The second component is disposed at a place in which cooling capability is greater than that of the first component so that allowable power of the second component at rated use is greater than allowable power of the first component. This electric compressor includes a temperature sensor which detects the temperature of the first component and a calculation unit which outputs an alarm signal when the detected temperature and a current flowing in the first component satisfy a predetermined condition.
