电磁驱动器的设计与分析 摘 要 随着电磁驱动的发展，电磁驱动已经应用到现在的各行各业。小到孩童时代的四驱车马达，大到工业应用的驱动装置，电磁驱动越来越被人们所重视。 电磁驱动之所以被人们所关注，也是主要由于其动能转化的机械低磨损率，机械磨损率的降低，一方面可以有效地降低工业设备维护的成本，一方面也有效地控制动能转化的效率。而且电磁驱动作为一个新能源，其低碳的理念也和可持续发展的战略紧扣。因此，电磁驱动的发展是一个顺应潮流的趋势。 本文主要介绍了电动机的国内外发展现状，电磁学的发展历程，进而延伸到一些基本的电磁学现象，从而了解电磁驱动器的工作原理以及由电磁驱动原理而来的一些技术应用，最后制作一个电磁驱动演示仪用来进行电磁驱动相关的数据收集。 关键词 电磁驱动；感应电机；电磁学 The design and analysis of electromagnetic actuator Abstract Along with the development of electromagnetic driving, electromagnetic drive has been applied to all walks of life. Four drive motors, the size of small to childhood, to the industrial application of actuating device, electromagnetic drive becomes more and more important for people. Electromagnetic drive have been attention by people, is mainly because of its kinetic energy into mechanical low wear rate, the rate of mechanical wear is reduced, on the one hand can effectively reduce the cost of industrial equipment maintenance, on the one hand, also effectively control the kinetic energy conversion efficiency. And electromagnetic drive as a new energy, its low carbon concept and strategy of sustainable development also closely. Therefore, the development of electromagnetic drive is a suit the trend of the trend. Development present situation at home and abroad, this article mainly introduced the motor development of electromagnetism, which extends to some of the basic electromagnetic phenomenon, so as to understand the working principle of electromagnetic drive and driven by electromagnetic principle and some technical application, and finally make a electromagnetic drive demonstration instrument used for electromagnetic drive related data collection and analysis. Key words electromagnetic drive，Induction motor，electromagnetism 目 录 摘 要 I Abstract II 第1章 绪论 1 1.1 引言 1 1.2 本文研究的内容 1 1.3 研究的创新点 1 1.4 本文篇章结构 2 第2章 国内外研究现状 3 2.1 电磁学理论的发展 3 2.2 国内外电磁驱动的技术应用 3 2.2.1 感应电机 3 2.2.2 电磁驱动泵 4 2.2.3 磁悬浮列车 4 第3章 电磁驱动器的分析 6 3.1 静电场 6 3.1.1 库伦定律 6 3.1.2 电场 6 3.2 磁场 7 3.2.1 奥斯特实验 8
