步进电机驱动器及细分控制原理(最全)word资料步进电机驱动器及细分控制原理步进电机驱动器原理:步进电机必须有驱动器和控制器才能正常工作。

驱动器的作用是对控制脉冲进行环形分配、功率放大,使步进电机绕组按一定顺序通电。

以两相步进电机为例,当给驱动器一个脉冲信号和一个正方向信号时,驱动器经过环形分配器和功率放大后,给电机绕组通电的顺序为AABB A A B B,其四个状态周而复始进行变化,电机顺时针转动;若方向信号变为负时,通电时序就变为AA B BA A BB,电机就逆时针转动。

随着电子技术的发展,功率放大电路由单电压电路、高低压电路发展到现在的斩波电路。

其基本原理是:在电机绕组回路中,串联一个电流检测回路,当绕组电流降低到某一下限值时,电流检测回路发出信号,控制高压开关管导通,让高压再次作用在绕组上,使绕组电流重新上升;当电流回升到上限值时,高压电源又自动断开。

重复上述过程,使绕组电流的平均值恒定,电流波形的波顶维持在预定数值上,解决了高低压电路在低频段工作时电流下凹的问题,使电机在低频段力矩增大。

步进电机一定时,供给驱动器的电压值对电机性能影响较大,电压越高,步进电机转速越高、加速度越大;在驱动器上一般设有相电流调节开关,相电流设的越大,步进电机转速越高、力距越大。

细分控制原理:在步进电机步距角不能满足使用要求时,可采用细分驱动器来驱动步进电机。

细分驱动器的原理是通过改变A,B相电流的大小,以改变合成磁场的夹角,从而可将一个步距角细分为多步。

定子A转子SNB B BSNA A(a(bAS NB B N S BS NA(c(d图3.2步进电机细分原理图仍以二相步进电机为例,当A、B相绕组同时通电时,转子将停在A、B相磁极中间,如图3.2。

若通电方向顺序按AA AABB BB BB AA AA AA BB BB BB AA,8个状态周而复始进行变化,电机顺时针转动;电机每转动一步,为45度,8个脉冲电机转一周。
