要約(英語): This paper proposes a low vibration stopping method by switching between the free-run and short-circuit braking modes of a compressor. Vibrations are generated by the bouncing of the rotor caused by load torque fluctuations. The proposed method suppresses the bouncing by stopping the motor during the suction process, thereby preventing the generation of a large torque. In order to stop the motor during the suction process, the proposed method switches from the free-run to short-circuit braking mode at the top dead center, which is the starting point of the suction process. Furthermore, the inrush current during the short-circuit braking mode is suppressed using a hysteresis current controller. The vibrations are evaluated under four pressure conditions using the conventional and proposed methods. The results show that, the proposed method achieves more than 50% reduction in the amplitudes of the vibrations at all four pressure conditions. Notably, the proposed method reduces the amplitude of the vibration by 71% under the high-pressure condition.
