Uni-polar Stepper Motor Driver Using Driver Transistors & L297

Unipolar Stepper Motor Driver Using Transistors and L297 (5)

High Current Unipolar Stepper Motor Controller project is based on chopper drive.  Chopper drive allows for use of higher voltage power supply for better performance and higher speed.  It uses SGS Thomson’s L297 IC and TIP142 transistor.
