摘要:为实现低成本、高性能的直线振荡电机控制,在介绍双定子结构及运行原理的基础上,采用磁路方法对双定子直线振荡电机进行了建模,根据建模结果,详细阐述了双定子直线振荡电机的变频、变压及复合控制方案,给出并对比了不同硬件驱动方案的优缺点。实验结果表明,采用磁路方法建立的模型是正确的,动子振荡频率与供电频率相等,动子所受电磁力与电枢电流成正比,通过变压控制可实现电机的振幅精确控制。受负载影响,电机在空载和负载时的共振点不同,且振荡电机的运行特性数学模型与驱动控制方案有关。

Abstract: In order to control linear oscillatory motors with low costs and high performances, based on the introduction of the two divided stators configuration and its working principle, the reluctance network method was introduced to conclude the mathematical model of the motor. Based on the mathematical model, the variable frequency control, the variable voltage control and the variable frequency plus voltage control were discussed in detail with their different characteristics. The experiment results show that, the oscillatory frequency of the mover is equal to the supply frequency and the force is proportional to the current of the winding. The variable voltage control can realize oscillatory amplitude control with high performance. For the loads, the resonance frequencies are different under load and noload conditions. The whole system models are different with different control methods.
Key words: linear oscillatory motor; model; drive; magnetic circuit
