The working principle of doublestators eddy current brake (DSECB) was introduced, then the brake torque formula of it was derived on the based of the theory of equivalent magnetic circuit, and the DSECB was simulated in 3D using finite element method. The influence of the electromagnetic parameters of the DSECB on the characteristic curve of the braking torque was analyzed in detail, which provided a reference for the optimal design of the DSECB.
