Abstract: This paper focused on a type of electromagnetic loss brake, and introduced its design solution and process. The temperature rising of the electromagnetic brake was also simulated by using thermodynamic simulation of Ansys. Based on the simulation of temperature rising, the design of electromagnetic scheme was completed. The two-dimensional finite element simulation model of the brake was also established by using Ansys-Maxwell. The electromagnetic properties of the brake were studied in the two-dimensional steady magnetic field. According to the simulation results and performance test of the principle prototype, the correctness of the design solution and process was verified.
