ABSTRACT:
An eddy current brake for use with exercise training devices, such as bicycle, ski and rowing exercise devices. The eddy current brake includes a nonmagnetic, electrically conductive disk that is rotatably mounted between one or more electromagnets. The electromagnets introduce eddy currents within the rotating disk. The disk is formed of a copper alloy having between approximately 5.0% to 15.0% zinc by weight. In one embodiment of the invention, the disk is formed of copper alloy 220, comprising 90.0% copper and 10.0% zinc.
