Circuit Schematic Unprogrammable Stepper Motor Controller using NE555 and CD4017 IC

Eltronicschool. - Now, there are many motor stepper controller that designed and developed using programmable circuit like Microcontroller. It is true make everything become easy but need some information about programming.

In here we will give you one circuit schematic of stepper motor controller without using programming that in this article mentioned with Unprogrammable Stepper Motor Controller. The main component in this circuit are NE555 and CD4017 IC like in Figure 1 below.

Circuit Schematic

Component Part
  1. NE555 IC

Description

Circuit schematic like in Figure 1 above is Unprogrammable Stepper Motor Controller using NE555 and CD4017 IC. According ElectronicsZone that published this circuit describe that the circuit shown above can be used to control a unipolar stepper motor which has FOUR coils (I’ve swiped it off an old fax machine). The above circuit can be for a motor current of up to about 500mA per winding with suitable heat sinks for the SL100. For higher currents power transistors like 2N3055 can be used as darlington pair along with SL100. The diodes are used to protect the transistor from transients.
