电动机是一种把电能轉变为机械能的机械。当电流沿着导綫通到电动机上的时候,便使它轉动,于是就帶动了連在它軸上的某种工作机械。在所有發动机中最簡便、最可靠、最經济又最完美的就是电动机,因此它在工業技术和日常生活上获得了極广泛的应用。先做一个小实驗为了熟悉电动机的基本構造和原理,讓我們試着制作一个能动的电动机模型。在制作电动机模型之前,讓我們先找一个馬蹄形永久磁鉄、一段比較粗的銅线(不論有没有絕緣皮的都行)、
A motor is a machine that converts electrical energy into mechanical energy. When the current is passed along the wire to the motor, it is turned so that it drives some kind of working machine attached to its shaft. The simplest, most reliable, most economical and perfect motor in all engines is the motor, so it has been widely used in industrial technology and daily life. Do a small experiment first In order to familiarize yourself with the basic structure and principle of the motor, let us try to make a dynamic motor model. Before making the motor model, let’s look for a horseshoe-shaped permanent magnet, a thicker copper wire (with or without insulation).
