Stepper Motor Connections

The configuration shown in Stepper Motor Configuration is an example of a typical stepper motor connection. Refer to Stepper Motor Phasing for information on motor phasing.

In this case, the effective motor voltage is half of the applied bus voltage. For example, an 80 V motor bus supply is needed to get 40 V across the motor.
