它又分为两相、三相和五相，两相步进角一般为1.8度，三相步进角一般为1.2度，而五相步进角一般为0.72度。
混合式步进电机的转子本身具有磁性，在同样的定子电流下产生的转矩要大于反应式步进电机，且其步距角通常也较小，经济型数控机床一般需用混合式步进电机驱动。
但混合转子的结构较复杂、转子惯量大，其快速性要低于反应式步进电机。
混合式步进电机特性输出转矩大，高转速。
电机发热小，噪音低，效率高。
高速停止平稳快速，无零速振荡运行平稳，振动噪声小。

2ZR-YJVZR-YJLVZR-YJYZR-YJLY交联聚乙烯绝缘阻燃聚氯乙烯/聚乙烯护套钢带铠装动力电缆敷设在室内、隧道及管道中，电缆不能承受机械外力作用。
聚乙烯的绝缘电阻高，耐电压好，介电系数小和介质损耗温度和变频率的影响也小，不但能满足传输性能的要求，能确保电缆的使用寿命。
为了减少回路间的相互串扰和外部干扰，电缆采用屏蔽结构。
电缆的屏蔽要求是根据不同场合分别采用：对绞组合屏蔽、对绞组成电缆的总屏蔽、对绞组合屏蔽后总屏蔽等方法。

伺服驱动器主要有三种控制方式；1.转矩控制：转矩控制方式是通过外部模拟量的输入或直接的地址的赋值来设定电机轴对外的输出转矩的大小，具体表现为10V对应5Nm的话，当外部模拟量设定为5V时电机轴输出为2.5Nm：如果电机轴负载低于2.5Nm时电机正转，外部负载等于2.5Nm时电机不转，大于2.5Nm时电机反转（通常在有重力负载情况下产生）。
可以通过即时的改变模拟量的设定来改变设定的力矩大小，也可通过通讯方式改变对应的地址的数值来实现。
