直流伺服电机的品种很多,根据磁场产生的方式,直流电机可分为他励式、永磁式,并励式、串励式和复励式五种。永磁式用氧化体、铝镍钴、稀土钻等软磁性材料建立激磁磁场。在结构上,直流伺服电机有一般电枢式、无槽电枢式、印刷电枢式、绕线盘式和空心杯电枢式等,为避免电刷换向器的接触,还有无刷直流伺服电机。根据控制方式,直流伺服电机可分为磁场控制方式和电枢控制方式。永磁直流伺服电机只能采用电枢控制方式,一般电磁式直流伺服电机大多也用电枢控制方式。
在数控机床中,进给系统常用的直流伺服电机主要有以下几种:
1)小惯性直流伺服电机
小惯性直流伺服电机因转动惯量小而得名。这类电机一般为永磁式,电枢绕组有无槽电枢式、印刷电枢式和空心杯电枢式三种。因为小惯量直流电机限度地减小电枢的转动惯量,所以能获得快的响应速度。在早期的数控机床上,这类伺服电机应用得比较多。
