Eight lead motors can also be connected in two ways: series and parallel. As with six lead motors, series operation gives
you less torque at high speeds, but may result in lower motor losses and less heating. In series operation, the motor should
be operated at 30% less than the unipolar rated current. The motors recommended in this manual should be connected in
parallel. The wiring diagrams for eight lead motors are shown on the following page.
