一种步进电机控制器
摘要：
本实用新型公开了一种步进电机控制器(20)，包括第一稳压器(23)、第二稳压器(24)、固定频率脉冲发生器(25)、与门(26)、第一电压比较器(27)、第二电压比较器(28)；第一稳压器(23)和第二稳压器(24)对输入电压信号ux(19)进行调制，为控制器、驱动器和步进电机供电，固定频率脉冲发生器(25)产生脉冲信号CP0，与门(26)接入脉冲信号CP0和输入电压信号ux(19)，输出脉冲信号CP，第一电压比较器(27)和第二电压比较器(28)识别输入信号ux(19)电压的高低，输出端接驱动器(21)；当输入高压直流电压信号UH时，步进电机正转，活塞升程增大，从而增大压缩比，当输入低压直流电压信号UL时，步进电机反转，活塞升程减小，从而降低压缩比，当输入0V的电压信号时，步进电机不工作，压缩比不变。
摘要（英）：

The utility model discloses a controller of stepping motor (20), including first stabiliser (23), second stabiliser (24), constant frequency impulse generator (25), AND gate (26), a voltage comparater (27), the 2nd voltage comparater (28), first stabiliser (23) and second stabiliser (24) are to apply signal voltage ux (19) modulate, for the controller, driver and step motor power supply, constant frequency impulse generator (25) produce pulse signal CP0, pulse signal CP0 and apply signal voltage ux (19) are inserted in AND gate (26), output pulse signal CP, the height of a voltage comparater (27) and the 2nd voltage comparater (28) discernment incoming signal ux (19) voltage, output termination driver (21), when input high voltage dc presses signal UH, step motor corotation, the increase of piston lift to scaling is pressed in the increase, when input low -voltage direct current presses signal UL, and the step motor reversal, the piston lift reduces, thereby reduces and press scaling, and when the voltage signal that inputs 0V, step motor is out of work, and scaling is unchangeable for the pressure.
