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.
