摘　　要：针对永磁直驱用电磁制动器制动力大、体积大、发热严重等问题,通过场路结合的方法,简化求解电磁吸力,运用Ansys有限元软件对电磁制动器进行场域求解分析,研究电磁制动器结构尺寸、气隙、绕组匝数、高压吸合时间、低压保持电压等参数对其性能的影响,并设计了一台220 kN的电磁制动器,通过样机的试验验证了计算和分析的正确性。The permanent magnetic direct drive electromagnetic brake has problems of big braking force,large volume and serious heat-ing,so the paper solves the electromagnetic force in a simple way through the method of field-circuit combination,and uses the Ansys finite element software to make field analysis of electromagnetic brakes.Then,the paper analyzes the influence of parameters such as size,air gap,winding turns,high voltage suction time and low voltage holding voltage on the performance of electromagnetic brake,and designs a 220 kN electromagnetic brake.Finally,the prototype test verifies the correctness of calculation and analysis.
