NI 9503 User Manual and Specifications
You can obtain improved high-speed performance with a 6-wire
motor by using a half-coil configuration shown in Figure 6. 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 used.
