PROBLEM TO BE SOLVED: To provide a controller of gas compressor, capable of preventing driving torque of the gas compressor from abruptly fluctuating in OFF operation of an electromagnetic clutch.SOLUTION: When an electromagnetic clutch 6 is turned off from a situation where the electromagnetic clutch 6 is turned on by current application to an electromagnet 23, opposite friction surfaces 20a, 24a of the electromagnetic clutch 6 are connected by electromagnetic force and then a compressor 1 is operated, a current control unit 32 of a control device 10 performs control so that a current value right before OFF operation applied to the electromagnet 23 gradually lowers to zero.SELECTED DRAWING: Figure 3 |
