Abstract:
This air compressor is provided with: a compressor main body that compresses air; a storage tank that stores a gas compressed by the compressor main body; a motor that drives the compressor main body by rotating a rotating shaft; and a control unit that controls the drive of the motor. In the cases where the value of a voltage to be supplied to the motor is lower than a first voltage value, the control unit detects a stop time of the compressor, and changes, on the basis of the stop time, operation stopping pressure, i.e., pressure for stopping the drive of the motor.
