28BYJ-48 5v Stepper Motor — How Many RPM Can I Spin This Thing?
RPM Configurations & Industrial Conveyor Belt — ArduSerie#68
Hello, I had to configure to the maximum RPM of the 28BYJ-48 Stepper Motor … but it only ran below 30 RPM :/
conclusion: this type of motor is used for cameras, air-conditioners, scanners etc when one wants certain accuracy rather than speed; for a design of a Industrial Conveyor Belt I think it is more suitable a simple DC motor; but this is subject to another post; Suggest, please, I'd love to hear suggestions:)
I want to use it for a prototype of an Industrial Conveyor Belt (very similar to the photo below…well, not really:/) but the speed of this type of stepper is very low … anyway, I have studied all the possible configurations of 28BYJ-48 Stepper Motor available for hobbyists and now I share it with you :)
My test bench for an industrial Conveyor Belt prototyping is a lot more humble…. Simple and ordinary. Sorry, it is not an engineering masterpiece. We’re just doing the initial explorations, me and my son …see video lab:)
I used: Cardboard, board for ULN2003 and 28BYJ-48 5v Stepper Motor, Thermal Printer Paper Rolls, Arduino Pro Mini, and hot glue.
Well, now I want the speed compatible with the speed of an old Turntable CD Vinyl Vitrola Vintage… remember its speed is 33 and a half RPM; but, just not:/ it does not reach a mere 30RPM:/ It’s frustrating!
Anyway here are the codes with the hardware and software configurations I used (in case you want to repeat the experiment there in your atelier:)
Code I & LAB I
Up there I’m using this Board: ULN2003 28BYJ-48 Stepper Motor & Arduino Uno IDE 1.8.5. The ideal result is?
Better solution: @waitingTimeOf_2s@5v resuts 14.5 rpm MaxCode II & LAB II
Up there I’m using: Adafruit Motor/Stepper/Servo Shield for Arduino kit — v1.2 & 28BYJ-48 Stepper Motor & Arduino Uno IDE 1.8.5. See comments above for the result:).
Of the settings available in the Adafruit Motor shield library, check which one fits best for the 28BYJ48 5v Stepper Motor and results in a higher RPM;)
In order to pass the test the stepper must complete the lap three times at least in both directions; then we put in a single direction and manually measured the RPM (see video); note that all the figures are on the maximum possible limit”]
Above the specified values the motor will stall:/ (see it for yourself).
Realize that we can get to 24 RPM, but we will have problems with motor heating in exchange for a fall in its useful life. Not an intelligent option, right?
Better solutiuon: 500speed@5v resuts 15 rpm MaxCode III & LAB III
I drew a circuit with L293D Motor Drive DIP 16 Pin IC; the code simply makes the motor spin at 24 RPM without stopping. The code is trivial, but what is important is the connections below;
Up there I removed the L293D chip from the Adafruit board and plugged in a breadboard. It was an emergency, I already provided the online chip …
Unique Solution: 24RPM@12vSo, in conclusion, of the options presented, L293D solo results in a higher RPM: 24 RPM at 12 v
And That’s it!
Let me know what you guys think…I see you guys in the next episode;)
