Finally, you can connect 8-wire stepper motors in a half-coil
configuration as shown in Figure 9. The half-coil configuration
sacrifices low-speed torque for better high-speed performance.
With this configuration, it is typically not possible to produce the
rated torque of the motor without the risk of the motor overheating
because only half of the windings are used.
Figure 9.
