Stepper Motor Circuits Northwestern Mechatronics Wiki The circuits for driving unipolar and bipolar stepper motors differ because bipolar stepper motors don't have a "center tap." However, it is possible to use bipolar drivers to drive unipolar steppers after some small modifications. Care must be taken in the driver circuit to protect against voltage spikes. Stepper motor Stepper motor performance is strongly dependent on the driver circuit. Torque curves may be extended to greater speeds if the stator poles can be reversed more quickly, the limiting factor being a combination of the winding inductance. To overcome the inductance and switch the windings quickly, one must increase the drive voltage.
