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.
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 ruclips.net/video/rTTI9cJcsJU/видео.html
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.
@@engineeringadventures1229 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 ?
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!
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.
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...
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.
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.
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.
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 🙏?
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.
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.
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
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.
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.
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
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.
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.
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.
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?
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.
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.
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
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 ?
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 ?
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: ruclips.net/video/Y4RB8efI6bs/видео.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.🙂

These are 18° permanent magnet motors (20 steps per revolution). You really need micro stepping if you need higher resolution.
which motor driver should we use for controlling many micro stepper motors??
Where to find flex cable to wire it ?

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
Can I use it with program it only with battery
