For maximum flexibility, you can connect 8-wire stepper motors
in series, parallel, or half-coil configurations. Connecting the
windings in a series configuration, as shown in Figure 7, produces
the most torque per amp but has the disadvantage of higher
inductance and poorer high-speed performance.
