Stepper Motor Configurations
This section describes the various industry-standard winding
configurationsfor stepper motors and shows how to connect them to a
MID-7604/7602. The MID-7604/7602 is compatible with all
configurationsof two-phase s tepper 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
showsa 6-wire and an 8-wire stepper motor. A 4-wire motor is the same as
a6 -wire motor except that the center taps (CT) are not brought out.
