Bipolar Stepper Motor Chopper Driver

3187 - Bipolar Stepper Motor Chopper Driver

Bipolar Stepper Motor Chopper DriverOur new bipolar chopper driver allows you to get better performance from your stepper motor. It uses a dual full bridge motor driver based on SGS Thompson chips L297 & L298.


  • Easily adjustable motor current (0.A to 2A)
  • Full and Half stepping modes
  • Step and Direction inputs
  • Synchroniseable when using multiple drivers
  • Enable input can be connected to ground to disable motor

Motor current for each phase is set using an on-board potentiometer and the controller is capable of handling motor winding currents of up to 2 Amps per phase.

It operates from a DC supply voltage of 9-36V. The drive provides all basic motor controls, including full or half stepping of bipolar steppers and direction control. Works with large bipolar stepper motors like the MO-101, MO-102 and MO-103.

All signals (Step, Direction, Enable) can be interfaced to external logic or a microcontroller. You can easily control the motor from your computer's parallel port or a serial stepper controller card!

This controller is perfect for desktop CNC applications.

  2. This іs the ρerfect blog foг
    anуboԁy who wоulԁ like to fіnd out about this topiс.
    You know a wholе lot іtѕ аlmοst
    hard to aгguе with you (not thаt I ρersonally would want to…ΗaHa).
    You сertаinly put а bгand new sρіn on а ѕubϳect that's been written about for many years. Wonderful stuff, just great!
