Abstract

A clamping device for exerting clamping force by an electromagnet comprises a first current command generating unit for generating a current command to be given to the electromagnet according to the target clamping force, a clamping force detecting unit for detecting the clamping force exerted by the electromagnet, and a second current command generating unit for generating a correction command for correcting the current command according to the detected value of the clamping force detected by the clamping force detecting unit. Thus, the clamping device capable of properly controlling the clamping force exerted by the electromagnet is provided.
