- Hi all, Here is the exploration video of a micro size stepper motor for my upcoming project.
In the video I am exploring a very tiny stepper motor. You can use this info for your projects as well.
"Coils are 12 - Ohm , Voltage is about 3V to 6V . Each half of the motor has 5 fingers and 5 spaces , 20 full steps total per rotation . Pad spacing is 0.85mm . soldering directly to the posts risks damaging these teensy steppers , best to use the connection tabs with a very low wattage iron."
- Jorge Joaquin Pareja from the comment section.

Thanks for the video. I disassembled a few of these motors to gather information about them. Coils are 12-Ohm, Voltage is about 3V to 6V. Each half of the motor has 5 fingers and 5 spaces, 20 full steps total per rotation. Pad spacing is 0.85mm. soldering directly to the posts risks damaging these teensy steppers, best to use the connection tabs with a very low wattage iron. If you can verify my findings you can update the video description so others can have accurate information about these. Again, thank you for this video.
Thank you very much. I'll update in the description.
I got this motor working with and A4988 driver board running 12 volts and the driver adjusted for 200mA. I made a PCB for it also but the pads for the motor need to be moved for a better fit. Here is a link to the video ua-cam.com/video/rTTI9cJcsJU/v-deo.html
Thanks for posting your video! I'm a micro motor junkie and this is good info.
This was very helpful. I have a handful of these motors and now I know how to connect and program them. Many thanks!
oh my god, i haven't seen a live programmed control of a motor in my life.. Waiting for ur upcoming project videos
thank you, sure. :)
Exactly what I was looking for. Thank you! 🙏
Glad it was helpful!
Awesome, I have been searching for Years to find how to control these little stepper motors without a driver board. You have answed every question I have had in this one video. I will run some tests soon. Thank You!
U will have to check the current requirement of your motor as well as if u need microstepping. If yes , an external driver is needed
Thanks for your review it’s really helpful! I bought a bunch of those micro steppers some time ago but didn’t try them yet. Now - it’s so easy as you don’t really need any hardware interface. However need to check what the current flows if you try hold the motor with your hand to not burn the mcu port.
Olexiy Bagriy thanks. The current is within GPIOs current capacity limits.

In other words, I don't need current limiting resistor or motor driver right ? My own micro stepper motor is 8mm 2 phase and 4 wires. Is my motor a bit higher in capacity than yours ? I want to program the set up using arduino because I do not have atmel programmer, do I need to worry about anything ?
Very nice work thank You. I was able to solder wires to tiny barrel one; use tiny wire loop some liquid flux and a blob of hot solder from side of point tip. With the loop one can hold wire in place by pulling slit lateral force.
These are 18° permanent magnet motors (20 steps per revolution). You really need micro stepping if you need higher resolution.
Thanks bro! Greetings from NZ!
3D Kiwi your welcome!
Awesome, been looking for this for some time! Thanks.
Great vid,nice intro to diy stepper motor use, thanks..
Do you recommend a dedicated Controller for this tiny motor that you may know of working with? I have been thinking for ages to build a tiny Pan Tilt camera with this motor alike, my big concerns were ordered them and then won't be able to control the speed of revolution but it seem you did and that was awesome! Thank you for sharing.
I have seen people driving these directly with the outputs of Arduino and Raspberry Pi. Isn't flyback current a concern?
It seems wise to drive these with something like the A4988 as Jorge Joaquin Pareja suggests, to avoid damaging microcontroller outputs, and to allow higher driving voltage...
I have exactly the same concern. I would at least add some flyback diodes.
Is there any tiny stepper driver that can fit inside a 2.5cm by 2.5cm space? Or can i use some sort of tiny icu to drive it with button cell. Trying to build a watch using these motors.
Very nice to watch and follow, need some more vid's
dude! youre good at this. Make more videos
Rakshith Prakash thanks for encouragement. Exciting videos coming soon!
Great video. Well done
Nice! This is what I've been look for. Thanks.
What kind of power do these tiny actuators have? As in how much could they push across a desk, for example. Any ideas? Cheers
Hi sir I have a question, you said that there's no need to use for motor driver because of it's current consumption. The question is do I have to use motor driver if I need multiple stepper motor? Thanks in advance. I learned a lot on your video
Beautiful, thank you!
I wouldn't recommend directly powering from the micrcocontroller even if it can easily power the tiny motor. Inductive kickback at some sudden stop could easily surpass the mcu's voltage level and fry the gpio or worse the mcu.
All you said is correct but no harm in experimenting when you are feeling lazy :D
Very good video. You should make more how-to videos for us amateurs!
Question: Have you tried running this stepper using 3.3 volts, e.g. from a Nano IoT?
Thank you, John
Thank you. I'll try to do so.
No, maybe someday.
hi there. just to say the tinyurl link is down and there's no ref to the motor in the desc or in the video, so it's not findable anymore. anyone to step in and provide some info 🙏?
Aliexpress is a great place to get a small stepper motors at very low prices.
Thank you so much 🙏🏽
Nice video
How much weight can they lift?
Owing to your video I now understood where to look for these. Thanks for your posting. But the link for buying these seems to be not working.
Anyone have any thoughts on controlling about 50 of these little motors at once? I always wanted to 3D print an array of about 50 hexagons and have them raise and lower slightly to look like a ripple is going through a panel or just have each of theblocks look like they are randomly popping up and sinking. I would embed a tiny nut in the backside of each block and as the motor spins it would raise and or lower the block. The mechanical side is figured out but I'm not sure how to control 50 of these simultaneously but independantly? Love the video and would love to hear anyones thoughhts.
which motor driver should we use for controlling many micro stepper motors??
This is a Great video. Thank you very much for this. by the way, me and my friends are also working on a project using these stepper motors. we need to get some linear movement using the screw axle. If you can, please help me with it. thanks..
Akalanka Kavinda yeah you can use these but the plastic nut part is not tight enough and it slips when there is minor obstacle. So you might need to find a way to tightening the nut part. All the best for your project.
Where's the current limiting when driving the stepper like this? The coils have a resistance of maybe a few tens of ohms (the several models I have are 10-50 ohm). The micro controller pins will be damaged when driving a resistance that low.
Thanks for the video, but how do you solder these? they are too small for me.
Thank you for this great video, only the link to the motor doesent seem to work. Could you direct us where to get that motor? Thanks much in advance
how would you make this useful by adding a leadscrew? the metal casing encapsulates both ends of the screw shaft
great job
thank you
Where to find flex cable to wire it ?
What are these small steppers used in? I reuse motors from broken electronics, but I have never seen such small motors..
focusing mechanism in a optical drive or cameras and similar applications.
@@engineeringadventures1229 Thanks. I'll be looking out for broken cameras, haha.
Is there anyway to operate the micro motors without the adurino board, straight from battery
nope, but a bare atmel uC can be programmed in arduino if you want to reduce size and price
Hi there, I have a project where I’d like to make a very small surface rise by about an inch and also lower by an inch using a switch or similar.
Think of the surface being about 30cm x 30cm with a small amount of weight. What is the best solution to do this?
Any help or suggestions would be welcome. Thanks.
if you were to keep the micro copper ribbon connecter (not shore of its correct name) what sort of connector would you need
Nice, can you please tell me where do you find the second and third variant of stepper motors that you showed in this video
a r aliexpress
Very interesting. Where can I find the code that can be copied? Thanks
Can I use it with program it only with battery
Hello. Please i want to run 32 steper motor of those kind. On a small project. Do i need to use for each it's own steper motor driver or i can just contrôle them with arduino if yes please tell me what i need to make them work.
Thanks in advance.
Great video. Worked great with Arduino. Didn't seem to have enough power out of a Nano to move the motor. Any suggestions (or tricks)?
Thank you. It's not advisable to drive directly from MCU pins. For experiment purpose you can use some buffer gate.
Does stepper motor can be use where torque is required?
Cool! :)
Thanks 🙂
Are you available for hire? I am designing a prototype and would like to use a micro motor to activate the spinning action for the device I have created. Thanks.

Can you use this for RC cars micro RC cars?
Where do you buy these motors? The link in the description does not work
I want smallest stepper motor for bike wiper.. can you help me?
Hey, what can you say about its torque? Can it move around objects 2-3 times its own weight?
Srijal Poojari I guess so
Nice! May you dislose the project you were working on?
Don't you need a H-bridge to drive this stepper motor ?
Hello! How much sound does this motor make when rotating? thank you!
My friend. I Bought a 2 fase 4 wire micro stepper and I would like to know if I can make it work without driver or arduino. but I don’t need it to step, I just need it to go a full side by side. There is any way to plug wires directly to the motor to do it?
I need to remove the micro pcb on it if there is any?
Very nice video! Thank you! Is it precise this small motor?
Silviu Seico yes, these are designed to be precise.
Hi, We are working on my project where we are building the robot legs (4 in each leg) using linear actuators. we need similar kind of motors which are small enough so it can fit in, and also have torque to support the whole body, would it be possible for you to provide sources where we can buy small stepper motors.
can you send a link for the mini step-motor ?
I planned to create micro robot with many servos. Is it really to connect to arduino more then 50 motors?
Виталий Богряшов for 50 motors you will need dedicated drivers for the sake of current and number of free pins.
Vitaliy, you need 16-Channel 12-bit PWM/Servo Drivers. Each one can drive 16 servos and it uses only 2 pins of your micro controller. These modules are addressable, and you can have up to 6 of them, that’s 96 servos on the same two pins! There is even a library for it called Adafruit Pwm Driver you can download, just google it. Very simple.
oppo f11 pro has this kinda of stepper motor which gets failed
Hello Vikas. Nice Video. Whats the torque of such small motors ?
Satyendra Verma thanks. I couldn't find the specs. Contact some manufacturers.
@@engineeringadventures1229 Thanks Vikas for the reply. Can you share where i can get the super small stepper motors that you used in the video ?

Hey Vikas I was looking forward to using micro stepper motors in a project . I picked up a few off Ali Express bit the distributor was not able to give me data sheets , do you have any data on the torque characterization of the ones you settled with ?

This link is might be help you.I coudnt understand this article.
Hi there EA, how much do these stepper motors weigh? im doing a lighter-Than--Air drone project. Thanks!
Hi Andrew, these are very low power motors and for different applications. For your application brushless motors are used. Share more info enthu.vikas@gmail.com, maybe I can hook you up with right people. Good day.
@@engineeringadventures1229 yea I don't want to use brushless motors because I'm not using propellers for thrust, I'm using 'fins' to propel the drone, so these small steppers could be useful for that. I'm currently using servos but servos but these steppers could be lighter
These motors barely have any torque for that, but you can experiment anyways.
I bought some from Amazon but non of the plastic nut parts have any grip on the shaft, anyone have a solution?
Rozco I couldn't find any solution either. If you find some solution do let me know!
Engineering Adventures found the pitch of the thread in the questions on amazon, it is 0.25mm, so I guess buying or 3d printing some nut with the threading is the solution, but getting it on the shaft would be the next problem
www.amazon.com/ask/questions/Tx2EQI8RGHH58GB/?
Just an idea what if to make a kind of nut of a drop made with a hot glue gun. Not sure if it really works and how long it lasts but anyway worth trying..
hot glue might be to soft , might work for a short while. Using some kind of formable plastic or hard clay could work, putting baby powder on the shaft before applying the plastic would prevent it from sticking to the shaft
I believe the plastic piece is designed to hold a piece of wire which will be pressed against the threads and ride in them. the plastic piece itself is not threaded.
From where did you get the 6x5 mm stepper motors? I am looking for something that size. Are they quality?

hello i want to make a project with micro stepper motor but i really have no idea how to do it so do you have an email to share with me your knowledge ?
Bruh went from Tech support to Electrical Engineer in 0.8 seconds.
whats the rating of the motor?
where can i get that?
you can buy it from banggood.com
Hi! I also have a hobby project that requires this size of stepper motors, and despite I tried the same test (using Arduino to directly drive the motor), I took this solution as temporary, thinking that I would hook it to a stepper driver later to get proper torque. But now that I watched your video, I think there's maybe no need for much more current for such a small motor, and so I'm considering to remove the steeper drivers, which would release a lot of used space! It's all about the torque, if it's enough or not. And by the way, those mini-stepper drivers use 18 degrees per step normally. I would love to see a follow up of your project!!
Here is my video, using GRBL to control the motors from the computer: ua-cam.com/video/Y4RB8efI6bs/v-deo.html
Hey, you may need to experiment with and without the driver and compare the torque which works for you.
Nice setup btw. It may take time but I'll try to bring the followup video asap.
I'm glad it was helpful to you. Thanks.🙂
