The eddy current braking torque on moving rotor considering magnetic path

자기 경로를 고려한 와전류 제동기의 회전자 발생 토크 특성

It requires to study on accurate control skill for the technical improvement of servo system require. It needs to study on brake that has constant-torque speed range as load. In this paper, braking torque of eddy current brake between electromagnet stator and rotating disk are analyzed. The torque-speed characteristics and proper disk construction are presented 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 are confirmed by experimental results.
