Stepper Motor Configurations
This section describes the various industry-standard winding
configurations for stepper motors and shows how to connect them to a
MID-7604/7602. The MID-7604/7602 is compatible with all
configurations of two-phase stepper motors.
Note
The MID-7604/7602 is not compatible with 5-lead unipolar stepper motors or
5-phase stepper motors.
2-phase stepper motors come in 4-, 6-, and 8-wire variations. Figure 17
shows a 6-wire and an 8-wire stepper motor. A 4-wire motor is the same as
a 6-wire motor except that the center taps (CT) are not brought out.
