Driving a bi-polar stepper motor with the SN754410NE double H-bridge and a Raspberry Pi

Bi-polar stepping motors use only two coils and are easily recognized because they only have four wires. Most unipolar steppers can be used in bipolar mode by ignoring the two centre taps. Because bi-polar stepping motors produce the rotating magnetic field by reversing the current in both coils, controlling them is much more complicated than […]
