Notice that an 8-wire motor wired in series is virtually identical to a 6-wire
motor and typically has the same high-torque but low-speed characteristics.
While a parallel configuration is not possible with a 6-wire motor, you can
usually obtain high-speed performance with the half-coil connection shown
in Figure 20. This 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 being used.
