补充资料：三相异步电动机
| 三相异步电动机 three-phase asynchronous motor 作电动机运行的三相异步电机。三相异步电动机转子的转速低于旋转磁场的转速，转子绕组因与磁场间存在着相对运动而感生电动势和电流，并与磁场相互作用产生电磁转矩，实现能量变换。与单相异步电动机相比，三相异步电动机运行性能好，并可节省各种材料。按转子结构的不同，三相异步电动机可分为笼式和绕线式两种。笼式转子的异步电动机结构简单、运行可靠、重量轻、价格便宜，得到了广泛的应用，其主要缺点是调速困难。绕线式三相异步电动机的转子和定子一样也设置了三相绕组并通过滑环、电刷与外部变阻器连接。调节变阻器电阻可以改善电动机的起动性能和调节电动机的转速。 |
