Description
Summary:As the technical improvement of servo-system, it is required to study on the accurate and robust control scheme. It needs to study on brake that has constant braking performance as speed variation of prime mover. In this paper, braking torque of eddy current braker between electromagnet stator and rotating disk are analyzed. The torque-speed characteristics and proper disk construction are represented in here. From the computer simulation results, it was found that eddy current braking torque is linear or approximately constant over the desired speed range depending on the rotor material, disk construction, pole number and pole displacement: of stator. These relations are confirmed by experimental results.
