PROBLEM TO BE SOLVED: To provide a system and method, capable of reducing rigidity of a spring in a suspension system, and thereby minimizing a vibration level in normal operation.SOLUTION: A control system for a closed cooling compressor includes a reciprocating compressor 3, and an electronic control device 2 for the reciprocating compressor 3. The electronic control device 2 is configured to: detect whether a rotational speed 23 of a rotating axle 10 is less than a predetermined speed level, after a command of power off of the reciprocating compressor 3; and then, when the detected rotational speed 23 is less than a speed level 34, before the rotating axle 10 completes next rotation, impart braking torque 36 for reducing the speed of the rotating axle 10.SELECTED DRAWING: Figure 2 |
