This application report shows that increasing the slew rates of the winding currents in a bipolar stepper motor pushes the motor to deliver more torque at high speeds. Simple voltage drives L/R drives and chopper drives are explained. L/R drives and chopper drives achieve slew rates higher than those achieved by simple voltage drives. Finally an example chopper drive is presented.
