摘　　要：基于磁阻原理设计了一种新型电磁离合器并阐述了其基本结构和工作原理。针对新型电磁离合器在一定的负载力矩下外齿发生跳齿失位的情况,对离合器进行了转矩理论分析计算,并利用Maxwell软件建立了新型电磁离合器的数值模型,分析了内外齿转差角的变化对新型电磁离合器电磁性能以及转矩特性的影响,研究了励磁线圈安匝数的变化对新型电磁离合器最大转矩的影响。研究结果表明:此新型电磁离合器的的设计方案可行,具有良好的应用前景。A new-type electromagnetic clutch is designed based on the magnetic resistance principle, and the paper introduces its basic structure and working principles. In view of the jumping of external gear of the new-type electromagnetic clutch under certain loading moment, the torque theoretic analysis calculation is performed for the clutch. And a numerical model is developed for the new clutch in Maxwell to analyze the effect of the variation of internal and external gear slip an- gles on the electromagnetic property and torque Characteristics, and study the effect of variation of number of ampere-turns of magnet exciting coil on the maximum torque of the new clutch, The study result shows that the design scheme for the new- type electromagnetic clutch is feasible, and that the clutch could be widely applied.
