A Unipolar Stepper Motor Driver

The drive circuits for Unipolar stepper motors are usually very simple. In its simplest form, a transistor or MOSFET is used to drive each section of the windings. With this design, the control signal must be supplied programmatically to the four windings of the unipolar stepper motor via an MCU. Continue reading ‘A Unipolar Stepper Motor Driver’ »
