  • Stepping Motors Fundamentals
    is negative. Current will flow in the. opposite direction when the polarity on each end is. swapped. A control circuit, known as an H-bridge, is. used to change the polarity on the ends of one wind-. ing. Every bipolar motor has two windings, therefore,. two H-bridge control circuits are needed for each
