To improve the power density of fast-response and easily controlled eddy current brakes for heavy-duty vehicles
the method of constructing a three-dimensional magnetic circuit by using axially convex toothed coils and overexcitation design technology are proposed. Based on the finite element method
the steady-state and quasi-steady-state electromagnetic field calculation models of the novel high-energy eddy current brake and two traditional eddy current brakes are established
and their magnetic circuit
air gap magnetic density
eddy current distribution and overexcitation braking characteristics are analyzed. The results show that the eddy current of the novel high-energy eddy current brake is distributed in the whole axial space on the inner surface of the rotor. When the speed is less than 3500r/min
its braking torque is significantly higher than the other two traditional eddy current brakes. And the overexcitation design can effectively improve the braking performance. Since the coil current density is increased to 3 times
the braking torque is increased by 0.65 times
which can provide instantaneous high torque for vehicle emergency braking and shorten the braking distance of the vehicle by 30%.

DOI: 10.1007/s11465-014-0314-x http://doi.org/10.1007/s11465-014-0314-x An analytical model has been developed for analyzing the braking torque in electromagnetic retarder by flux tube and armature reaction method. The magnetic field distribution in air gap, the eddy current induced in the rotor and the braking torque are calculated by the developed model. Two-dimensional and three-dimensional finite element models for retarder have also been developed. Results from the analytical model are compared with those from finite element models. The validity of these three models is checked by the comparison of the theoretical predictions and the measurements from an experimental prototype. The influencing factors of braking torque have been studied.
