The Cheapest Stepper Motor And How You Use It (28BYJ-48 & ULN2003 Arduino Tutorial!) (WITH CODE!)
Stepper Motor is a motor controlled by a series of electromagnetic coils. The center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not, creating magnetic fields which repulse or attract the magnets on the shaft, causing the motor to rotate.
This design allows for very precious control of the motor,There are two basic types of stepper motors, unipolar steppers and bipolar steppers.
In this instructable, I will talk about a Unipolar Stepper Motor 28-BYJ48.
The unipolar stepper motor has five or six wires and four coils (actually two coils divided by center connections on each coil). The center connections of the coils are tied together and used as the power connection. They are called unipolar steppers because power always comes in on this one pole.
There are many types of Drivers, L293, ULN2003, A3967SLB, And More,
The 28-BYJ48 Even comes with Breakout using ULN2003 As a Motor driver chip.
Specification for this Motor "And you can download datasheet from the attachment"
Rated voltage：5VDC
Number of Phase 4
Speed Variation Ratio 1/64
Stride Angle 5.625° /64
Frequency 100Hz
DC resistance 50Ω±7%(25℃)
Idle In-traction Frequency > 600Hz
Idle Out-traction Frequency > 1000Hz
In-traction Torque >34.3mN.m(120Hz)
Self-positioning Torque >34.3mN.m
Friction torque 600-1200 gf.cm
Pull in torque 300 gf.cm
Insulation grade A
and the schematics of this breakout shown like the Pictures on the attachment
Note that if you want to use L293 instead of ULN2003, you will need to leave Red wire No connection.
The Arduino IDE Support a Library for Stepper Motor, Very Easy to use, After Connect Motor with arduino You can Upload the Sketch on to the arduino.
You must take something in consideration:
This Motor has a Gear ratio of 64, and Stride Angle 5.625° so this motor has a 4096 Steps.
