Abstract:
In a chip evacuation device that evacuates chips produced in a machine tool to outside of the machine tool, a synchronous motor is used as a power source for the chip evacuation device. A load on the synchronous motor is monitored and a number of rotation or a direction of rotation of the synchronous motor is changed when it is determined that the load exceeds a preset threshold.
