Description
Summary:	To improve the braking performance of existing permanent magnet retarders, a torque adjustable permanent magnet retarder(TA-PMR) is proposed. The structure and working principle of the TA-PMR are introduced. A finite element method is used to establish an electromagnetic field analysis model for the TA-PMR. The electromagnetic braking performance of the TA-PMR is studied using finite element method. The air gap magnetic density and braking torque of the TA-PMR are obtained under different operating conditions. The results indicate that the no-load torque of the TA-PMR was 0.85Nm, while the maximum eddy current braking torque of the TA-PMR was 1436Nm.
