Bipolar Stepper Motor Driver Circuit


Posted on Aug 21, 2012

A 4017 decade counter/divider driven from a low-frequency oscillator (Ul-a and Ul-b) is used to drive transistor switches to sequence the windings, as is needed. MOT1 is a 12-V stepper motor. R9 and RIO are selected for the motor`s current rating. A 3.3-Hz signal from Ul will cause the motor to run at 1 rpm,
