Abstract
An electromagnetic brake system includes a motor having a rotor with a rotatable disk fixed to the rotor and an electromagnetic brake disposed about the disk to selectively prevent rotation of the rotor. The electromagnetic brake is carried on a resilient element so that it is suspended relative to the disk and isolated from the remainder of the system reducing the propagation of structural and airborne noise generated by actuation of the electromagnetic brake.
