Fun Stepper Motor Schematic

It is commonly used in photocopy machines printers cnc machines robotics etc where precision motion steps and controls are needed.

Stepper motor schematic. It is a unipolar type stepper motor with 5 wire configuration. Instead of making full turns like a normal motor stepper motor make steps one small degree at a time. Basically stepper motors are classified in to unipolar stepper motors and bipolar stepper motors based on the windings of the stator.

A bipolar stepper motor must be driven in. The unipolar motor so have five six or eight leads. Stepper motor is an impressive piece of engineering.

Now as shown in the circuit diagram the 555 circuit here is to generate clock or the square wave. Motor interface type must be set to 1 when using a driver. Hence we must make the driver interactive enough to be able to take command from the user and do the required kind of stepping.

The two winding to a pole may have one lead common i e. A 12v stepper motor is used in this project. These can be unipolar or bipolar.

In unipolar step motor there are two winding per phase. A unipolar stepper motor must be driven in unipolar mode. Stepper motors fall into 3 main categories namely unipolar bipolar or hybrid unipolar bipolar.

Define dirpin 2 define steppin 3 define motorinterfacetype 1 create a new instance of the accelstepper class. Eight lead unipolar facilitates both series and. And hence this stepper motor driver circuit is essentially a binary counter circuit.
