An air purge system includes an electric motor having an air purge device which supplies air to a space around the outer peripheral surface of an output shaft, an information acquisition unit which acquires operation information of the electric motor, and an air control unit, which controls the amount of air supplied from the air purge device in response to the acquired operation information. The air control unit increases the amount of the air supplied from the air purge device when the information acquisition unit acquires deceleration operation information of the electric motor. |
