Drive a DC Stepping Motor - by Bill Hung Spring 2005
(Left) The whole DC Stepping Motor with driver circuit. 555 timer chip generates a clock for the 7404 inverter circuit. The four 7404 inverters forms a digital self-starting counter with the 4 Flip-Flop. The digital signal is fed into 4 bi-polar amplifier to drive a 5W DC stepping motor.
