Electromagnetic brake
The present invention relates to an electromagnetic brake. In an electromagnetic brake (11) comprising an electromagnetic brake body (13) having yoke members (15a and 15b) with a coil winding (14) and a brake movable member (16) formed of a magnetic material, which is disposed via an air gap (18) in a magnetic path formed by the electromagnetic brake body (13) and is fixed to a motor rotating shaft (2b), a magnetic fluid (20)is filled in the air gap (18), and a sealing member (19) for rotatably sealing the motor rotating shaft (2b) is disposed between the electromagnetic brake body (13) and the motor rotating shaft (2b) to prevent the magnetic fluid (20) from leaking, whereby the electromagnetic brake (11)is applied when the coil winding (14) is excited.
