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 wiring
diagrams for eight lead motors are shown below.
