一般地讲，小型球磨机的电动机采用低压电，过了3KW的大中型球磨机的主电机宜用高电压。适用于球磨机拖动的电动机介绍异步电动机除小型球磨机应用鼠笼型电动机拖动以外，中小型球磨机大多数均采用三相绕线型异步电动机拖动。绕线型电动机有JR，JRQ，及YR等系列。异步电动机在球磨机拖动上的主要有缺点是:装备简单价格便宜;有足够的启动转矩,可直接启动球磨机;它的启动转矩可通过接入转子绕组的串联电阻来控制频敏变阻器在电动机起动过程中会自动地使转子电路中的电阻发生改变,以适应改善启动性能的要求.启动时,只要合上电源开关,电动机就在频敏变阻器随转子转速上升而自动减少串在转子电路中的阻力,使电动机转速平稳地上升。
