Abstract

[PROBLEMS] A technique for a variable air volume type electromagnetic pump for compressing air and discharging the compressed air. Even in a low air volume operation, the technique enables an automatic stopper mechanism to operate appropriately when an abnormality occurs in a diaphragm, and this enables the electromagnetic pump to operate appropriately. [MEANS FOR SOLVING PROBLEMS] The electromagnetic pump (100) has the following control modes for vibrationally driving a vibrator (140) by using electromagnets (120, 130): a stop control mode for stopping the drive when the amplitude of the vibrator (140) reaches a preset specific amplitude, a first drive control mode for controlling the drive so that the vibrator (140) vibrates at a first amplitude smaller than the specific amplitude, and a second drive control mode for controlling the drive so that the vibrator (140) vibrates at a second amplitude greater than the specific amplitude.
