摘要

本文对转子呈螺旋运动的三相永磁同步作动器进行了计算机分析。该驱动器有一个三相绕组,一个定子,一个转子和一个电源。执行器转子的螺旋运动是通过扭曲转子上的永磁体来实现的。这样,作用在转子上的合力电磁力被分成两个单独的力:线性和旋转。在三维有限元软件中进行参数化分析,研究了永磁体倾斜角度对这些力的影响。通过三维有限元和电路联合仿真分析,进一步分析了在不同电源频率下具有最优倾斜角的作动器。本文对执行机构的机电特性进行了计算和讨论。

PM BLDC Actuator with Helical Motion of the Rotor For Industrial Applications
this paper presents a computer analysis of a 3-phase permanent magnet synchronous actuator with helical movement of the rotor. This actuator has one 3-phase winding, one stator, one rotor, and one power supply. Helical motion of the actuator’s rotor is achieved by skewing the permanent magnets on the rotor. This way the resultant electromagnetic force acting on the rotor is split for two individual forces: linear and rotary. The influence of the permanent magnets’ skew angle on these forces is studied by running parametric analyses in 3D FEM software. The actuator with optimal skew angle was analyzed further at different supply frequencies by a 3D FEM and circuit co-simulation analysis. The electromechanical characteristics of the actuator are calculated and discussed in the paper.
