摘　　要：建立感应驱动器的数学模型，并基于Ansofi公司的Maxwell 3-D仿真环境，建立了感应驱动器的3-D有限元模型。利用3-D涡流场求解器对感应驱动器性能进行分析，给出磁场和安培力的分布情况，比较电枢分片前后其内部涡流密度的差异，研究电枢材料对性能的驱动器性能的影响。结果表明：电枢尾部与励磁线圈之间的磁场最强，电枢尾部外表面处的涡流最大，受到的电磁力也最大，选用铝质电枢有利于提高驱动器的性能。This paper builds the mathematical model and 3-demensions finite element model based on the simulative environment of Ansoft for the induction driver. 3-demensions eddy current field solver is employed for the performance analysis of the induction driver. The distributions of magnetic field and ampere force on the armature are given. The eddy current density difference between the whole armature and the section armature is compared. The effect of the armature material on the performance of the induction driver is investigated. Results show that the magnetic field between the armature tail and the inner surface of the excited coil is the strongest, that the eddy current in the outer surface of the armature tail is the largest and the corresponding electromagnetic force is also the largest. The aluminum armature is useful to enhance the performance of the induction driver.
