With the aim of researching the braking characteristics of the electromagnetic eddy current brake and the influence of various factors on the braking performance, in this paper, a 3D transient field simulation model is established based on the finite element method with the DS-50 eddy current brake as an object, and verifies the reasonableness of the model by analyzing the change of the rotation angle of the rotor of the eddy current brake with time, so that this model to be used to simulate the electromagnetic characteristics of the eddy current brake as well as the influencing factors of the braking torque. The results show that when the speed is less than 50 rpm, the braking torque increases rapidly with the increase of speed, and after the speed reaches 75 rpm, the braking torque gradually shows a slow increase; as the excitation current is increased, the braking torque exhibits a gradually increasing trend and the peak torque increases according to a linear function.
