  • In order to optimize the design parameters, and improve the braking performance for permanent magnet retarder, its magnetization vector distribution was analyzed by complex vector method, its eddy loss was calculated in rotor, the computation formulae of its braking torque were derived in order to reflect the mutual relations among braking torque and different design parameters.The comparison of bench test result and computation result shows that the maximum error is less than 6%, so the computation formulae are feasible, and they are approximate to compute retarder braking torque.
