直流伺服电机有如下特点：
①稳定性好。直流伺服电机具有下垂的机械性，能在较宽的调速范围内稳定运行。
②可控性好。直流伺服电机具有线性的调节特性，能使转速正比于控制电压的大小；转向取决于控制电压的极性；控制电压为零时，转子惯性很小，能立即停止。
③响应迅速。直流伺服电机具有较大的起动转矩和较小的转动惯量，在控制信号增加、减小或消失的瞬间，直流伺服电机能快速起动、快速增速、快速减速和快速停止。
④控制功率低，损耗小。
⑤转矩大。直流伺服电机广泛应用在宽调速系统和精确位置控制系统中，其输出功率一般为1～600W，也有达数千瓦。电压有6V、9V、12V、24V、27V、48V、110V、220V等。转速可达1500～1600r/min。 | |
