Abstract
An improved eddy current braking system for fly wheel braked exercise equipment includes the use of a flat aluminum disc and electromagnets to either side of the disc adjacent to the periphery thereof, with the electromagnets containing multiple pole pieces to multiply the torque so as to reduce heating and power consumption. The utilization of aluminum achieves a flat torque versus speed characteristic vis-a-vis copper discs over the normal operating speed range. Additionally, the utilization of aluminum prevents the warpage associated with copper.
