Unipolar Drives
Motor phase winding current is switched in only one direction (typically to ground).
• Simple low cost drive circuit
• Requires center tap winding
• Low Output Torque
• 6 & 8 lead motors

Bipolar Drives
• Motor phase winding current is switched in both directions.
• Higher cost drive circuit
• Higher Output Torque
• Approximately 1.4 X Unipolar Drive
• 4, 6, & 8 lead motors
• 8 Lead Motors are more efficient when used with a bipolar drive.
