As an 8 wire motor, the MOT-128 can be wired up in a number of ways. Unipolar configurations use the half coils in sequence and offer about half the torque of the full coil configurations. Parallel and series configurations use the whole coil but require a bipolar driver.

Series configurations offer higher torque at lower speeds but also result in higher inductance causing instability at high speed.

In general we recommend wiring the motor coils in a parallel configuration. This tends to flatten out the speed-torque curve and allows for greater motor speeds.
