摘　　要：永磁直线无刷直流电动机作为一种动力源,具有动态性能好、零齿槽效应和零引力、低速性能好等特点,在高精度定位装置上有广泛的应用.基于ANSOFT公司的Maxwell 2D的仿真环境,本文建立了应用于分段供电环形过山车中的永磁直线无刷直流电动机的仿真模型.在所建立模型的基础上,对永磁直线无刷直流电动机的基本特性进行了有限元分析,仿真特性曲线说明了设计参数的可行性,以及利用Maxwell进行电磁场计算的准确性,可以用来指导这种新型电机及其控制系统的设计.As a drive mechanism, linear permanent magnets brushless DC motor （LPMBD- CM） possesses many advantages,such as high position accuracy,high system dynamics, zero cogging, zero attractive force and so on , so it has a extensive application in position system. In this paper, the simulation model of LPMBDCM used in the partition power supply of ringlike roller coaster is set up based on the Maxwell 2D of ANSOFT corporation. Based on established model, the finite element analysis on the LPMBDCM is carried out, the simulation characteristic curve can explain the design parameters feasibility, and the electromagnetic field computation using Maxwell is valid. The results of simulation can be used to design this new type of machine and control system.
