Abstract：In this paper, a series magnetic path hybrid excitation linear eddy current brake was presented. The influence of the end effects on the eddy current brake was studied. First, the structure and the working principles of the proposed brake were introduced. Second, its analytical model was derived using the equivalent magnetic circuit method and Maxwell equations. Then, the influence of the longitudinal and transverse end effects on the braking force characteristic was analyzed. The modified analytical model was obtained by introducing some correction factors. Finally, the modified analytical model was verified using the 3D finite element method. The results show that the modified analytical model can predict the braking force characteristic of the proposed brake accurately.
