3-D eddy current analysis in moving conductor of permanent magnet type of retarder using moving coordinate system

A 3-D DC steady state eddy current analysis of a permanent magnet type retarder which rotates at high speed is carried out using a moving coordinate system. The method of DC steady state analysis using a moving coordinate system is described. The calculated results, braking torque etc., are compared with measured ones.
