BIPOLAR STEPPER MOTORS APPLICATIONS
Bipolar stepper motors can be driven with one
L6506 or L297, two full bridge BCD drivers and
very few external components. Together these
three chips form a complete microprocessor-to-
stepper motor interface is realized.
Figure 18: Two Phase Bipolar Stepper Motor Control Circuit with Chopper Current Control
Figure 19: Two Phase Bipolar Stepper Motor Control Circuit with Chopper Current Control and Translator
As shown in Fig. 18 and Fig. 19, the controller
connect directly to the two bridge BCD drivers.
External component are minimalized: an R.C. net-
work to set the chopper frequency, a resistive di-
vider (R1; R2) to establish the comparator refer-
ence voltage and a snubber network made by R
and C in series (See DC Motor Speed Control).
