【摘要】：直线电机作为新型的动力装置,相比于传统的“旋转电机+滚珠丝杠”的传动方式,不仅取消了机械传动链带来的不良影响,还具有结构简单、反应速度快、系统效率高等优点,越来越受到人们的广泛关注。本文针对应用于闸机门的驱动装置,需要研究开发一种圆筒型混合式直线步进电机。以门控系统为应用对象,在电机结构及其优化分析、气隙和相位误差对推力的影响、及动定子齿宽齿距一致时不同齿宽齿距比谐波抑制等这些方面进行了研究。文章主要针对圆筒型混合式直线步进电机的研究与分析展开工作,主要包括以下几个方面:首先,详细介绍了圆筒型混合式直线步进电机的结构特点及其工作原理。根据圆筒型混合式直线步进电机的结构特性,分析了该电机的气隙磁导计算方法,并推导了该电机的数学方程。其次,在结合磁路法以及有限元法的基础上,对圆筒型混合式直线步进电机各种重要的参数进行优化分析,得到了相应的优化参数;得到了圆筒型混合式直线步进电机设计的基本方法。最后,结合圆筒型混合式直线步进电机在实际工作环境中运行时,所能受到的影响因素,如气隙不均匀、相位误差和控制绕组断电时定位误差等,对其进行仿真分析。通过本文的研究与分析为以后的圆筒型混合式直线电机理论设计提供一定的理论指导。
[Abstract]:As a new type of power device, linear motor not only cancels the bad effect of mechanical transmission chain, but also has simple structure and fast reaction speed, compared with the traditional drive mode of "rotating motor ball screw".More and more attention has been paid to the high efficiency of the system.In this paper, we need to develop a cylindrical hybrid linear stepping motor for the driving device of gate door.In this paper, the structure of motor and its optimization analysis, the influence of air gap and phase error on thrust, and harmonic suppression of different tooth width and tooth spacing ratio are studied in this paper.This paper mainly focuses on the research and analysis of cylindrical hybrid linear stepping motor, including the following aspects: firstly, the structure characteristics and working principle of cylindrical hybrid linear stepping motor are introduced in detail.According to the structural characteristics of cylindrical hybrid linear stepping motor, the calculation method of air-gap magnetic conductance of the motor is analyzed, and the mathematical equation of the motor is deduced.Secondly, based on the combination of magnetic circuit method and finite element method, various important parameters of cylindrical hybrid linear stepping motor are optimized and the corresponding optimization parameters are obtained.The basic design method of cylindrical hybrid linear stepping motor is obtained.Finally, the influence factors such as air gap nonuniformity, phase error and position error of control winding when the cylindrical hybrid linear stepping motor is running in the actual working environment are simulated and analyzed.The research and analysis in this paper provide some theoretical guidance for the theoretical design of cylindrical hybrid linear motor.
