施耐德 BMXFCA152
电机结构不同:直流电动机一般有电刷还有换向器,而交流电动机一般没有。
用途不同:直流电动机主要用于调速较广泛的动力机械或其他设备,而交流电动机主要用于调速范围不太大的动力机械或其他设备。
工作方式不同:直流电机是磁场不动导体在磁场中运动,交流电机是磁场旋转运动而导体不动。
直流电动机调速性能好,所谓调速性能,是指电动机在负载的条件下,根据需要人为地改变电动机的转速。但此类电机不宜在高温、易燃等环境下操作。
而且由于电机中需要以碳刷作为电流变换器的部件,所以需要定期清理炭刷磨擦所产生的污物。无碳刷之马达称为无刷马达,相对于有刷,无刷马达因为少了碳刷与轴的摩擦因此较省电也比较安静。
