Even if you don't have a meter you can still identify the wires of each coil. With all the wires isolated from each other, turn the motor shaft. It should rotate quite freely. Now connect any two wires together and turn the shaft again. If the wires are from the same coil there will be a noticeable resistance to the turning force. If they're not from the same coil the shaft will rotate freely.
That is awsome! I can make a water wheel and a voltage regultor and im lit up or even charge my phone in the woods. Great video im just loving these tutorials. You should see the nightmare my bedroom has become 😛
hi, using this engine I would like to make a 12 volt battery charger to position my gokart as a chain tensioner...how many amps can I get? the battery is 6.5 amps...
I pulled a couple of stepper motors from my piles. Each of them had 6 wires coming out of them. I checked the two pairs with highest resistence around 150 or so ohms. With slight turn each pair showed somewhere around 25 volts AC on each pair of them wires on both motors. I think that should do it for me. I suppose I better use higher capacitance and voltage values, Along with some resistors and a pack of LEDs I would think. Does that sound about right?
Hi, I want to make a hand crank flash light with a stepper motor, like you do here, but I have some doubts. Can you help me? I have a 28v 4 wires hybrid stepper and, from what I read here, I'm going to get around 56v... So, is there any way to regulate it down without a step down or some kind of specific regulator? I want to use a supercapacitor as well, is that a problem? (They normally have only 5v.) Thanks!
Curious if you or anyone can answer a quick question. What is the significance of coil resistance? You mention in your video it’s 8 Ohms for this motor. Does a higher number for resistance mean it’s harder to turn? For example a 32 Ohms motor would be quite a bit harder to spin than one rated at 1.5 Ohms? Thanks!
Hello, If anyone has trouble noting the components, they are the following: - bridge rectifier is KBL04, - capacitors are electrolytic ones (25 V, 4700 uF), 😉😆
You know, a really cool thing to do is connect two bipolar motors (mtra & mtrB) to each other (coil a to A, b to B)... not power supply... turn one motor with finger, other turns by similar amount in similar direction. This ALSO works with some small DC motors as well (but not too small ... like the motors from old 1980s cassette players, the tiny hobby motors didnt seem to work with each other or with a bigger motor driving them for some reason).
Nice vid... cheers.... Can I ask , i use nema 17 with full bridge rectifier , but i am curious why it can lit up LED in both left & right turn of the motor shaft ? Is that already has been rectified to DC , supposed to light up only in 1 way turn ...
Great video I appreciate the tutorial. I made a really nice water wheel and gear system for mine and made a 300 led lamp and a small tray with a water pump and its amazing for camping and on other side i have a 5 volt voltage regulator set up so i can charge my 18650's and phone! Im new at this stuff but id like to add boost converter aswell and see if that will give me a steady 12 volt for the lamp etc. All fits in a small case. Thanks again . im a little excited can you tell!!!
This can be seen at 2:21 - 2:27 The ( - ) marked on the capacitor is connected to the ( - ) marked on the rectifier. Though it might not be obvious, this can also be seen from the schematic 0:32 , if you look closely at the orientation of the diodes and the outputs. Although the polarity of the capacitor isn't specified in the drawing the wires leading to it are marked as (+) and (-) thus giving the answer.
+Ludic Science aside of storing electricity what is the advantage of using a capacitor in line with a dynamo. because i watched a video which he put a ceramic capacitor fixed in the dynamo thanks
do not remember is an old video, but any stepper will work. The output voltage and current generated will be roughly the same as the voltage and current the motor is designed to work with
thanks . i always been thinking for the specs . im making a energy harvester bike for my FYP . so i need to know the voltage and current to charge my SLA battery . Its ok then if u dont remember . but if u found the specs , can u catch up me immediately ? sory for my bad english >o
can the stepper motor charge the capacitor to its full voltage? I am going to build this circuit, instead i am going to use a dc motor knob to turn the knob on the stepper motor, so will i get a voltage that is at least over 30v? just want your opinion.
+agashcool123 The voltage depends on the particular motor that you have. Check the rated voltage of your motor. If you connect the coils in series, you cang get a maximum voltage 2 times the motor working voltage
I built a similar circuit but my led did not continue to glow. it will only glow instantly whenever i turn the motor. I have a capacitor but i did not connect any resistors.
I have a flyback transformer of 5 pins. I found him in the plasma balls. There are two pins of 8 ohms. which is the primary coil? Does this transformer can be used for the Tesla coil?
Capacitors used can be seen at 2:25 25 V 4700 μF as for the resistor, I'll take a wild stab at it: Judging by the colors I'd say it's brown(1), grey(8), brown(1, how many zeros added to the first two numbers), so it's 180 Ω. Using ledcalc (dot com) and punching in the values: Supplied voltage: 15 V (I just guessed this) Voltage drop across LED: 3 V Led Current: 20 mA Number of LEDs: 4 Gives 150 Ω for the exact resistance and existing nearest higher value resistor is 180 Ω. To do this by hand: Supplied voltage - voltage used by components = voltage left over. There are 4 LEDs in series consuming each 3 volts, that 4 * 3 V = 12 V 15 V - 12 V = 3 V this 3 V is the voltage left over, and has to be used in order to achieve balance. This is why we add a resistor to consume it, the resistor needs to waste the remaining 3 V. But how do we know the rating? Well: R = V / I V = Voltage to waste = 3 V I = Current = 20mA = 0.020 A So 3 V / 0.02A = 150 Ω, and the nearest higher rated resistor is 180 Ω. Always play it safe and go higher than the exact calculated one. Same goes for capacitors, in general, the voltage rating of a capacitor is the *maximum* it can take. This is how I understand things, I hope this helped someone. And *please do correct any mistakes* , so I won't be spreading lies across the internet. For great justice.
Hi your videos are very informative. can i ask if you have no load, lets say no led, will the capacitor heats up the coils of the stepper motor once the capacitor is fully charged?
I made a water wheel with a 3d printer plastic wire coil and bicycle hub and have to set up gears yet but with a voltage regulator should be awesome. But need to k now what size capacitor and rectifier have. A/c 25 amp 1000 volt or less. Help meeeee. Thanks this is awesome . will be better than old bicycle light wheel generator
+itzlagana What you're looking for is called a voltage regulator. You can tune the voltage on those by using a pair of resistors (aka voltage divider). Mouser and Digikey are good sources for parts.

Nice video, but did you take any measure about the mA you can draw? Steppers are known to provide high voltage (may be too high for small applications) but the current is quite low. Any suggestion?
Hi, you could try with a buck converter, which brings down voltage stepping up current. Of course, you should get a bigger tension from the stepper than you want on the output of the converter. Cheers.
dear LS i watch ur every project with great interest .....for this project i have a question ...can i use this generator to charge my mobile or rechargeable battery ?
What is the resistor value that you used with the LEDs? And what is the purpose of the resistor in the circuit? (electronics isn't my area of knowledge...yet) btw great video!
they have no serial number. bridge rectifiers are sold by voltage and current rating. for this proyect you need one that handles 50 volts and 1 amp (or more)
Even if you don't have a meter you can still identify the wires of each coil.
With all the wires isolated from each other, turn the motor shaft. It should rotate quite freely.
Now connect any two wires together and turn the shaft again.
If the wires are from the same coil there will be a noticeable resistance to the turning force.
If they're not from the same coil the shaft will rotate freely.
Nice trick

Thanks again . im a little excited can you tell!!!
So.....what size/rating of a Stepper motor should be used for a VAWT?
how much voltage are you getting by rotating with hand? that numbers on multimeter are these in milli volts or volts?
*I have a problem with polarity of capacitors, do i connect capacitors' + to rectifiers' + or do i do it like in battery case + connected to ( - )?*
This can be seen at 2:21 - 2:27
The ( - ) marked on the capacitor is connected to the ( - ) marked on the rectifier.
Though it might not be obvious, this can also be seen from the schematic 0:32 , if you look closely at the orientation of the diodes and the outputs. Although the polarity of the capacitor isn't specified in the drawing the wires leading to it are marked as (+) and (-) thus giving the answer.
what about connecting the two coil in series before the rectifier to minimize the number of diode to use for rectifier.
is that okay and same result
+JD Punzalan Yes you can do that, but you have to check the phases of the coils. If they are not in phase, their voltages will cancel out.
+Ludic Science
aside of storing electricity
what is the advantage of using a capacitor in line with a dynamo.
because i watched a video which he put a ceramic capacitor fixed in the dynamo
thanks
+JD Punzalan It acts as a filter, to smooth the waveform because the output from the motor is a rectified sine wave.
Can I do it with unipolar stepper?
Good work bro 👍
Please give me a list of the electrical components
what number for that bridge diode ?and for the capacitor how much the value ?
+Raditya low cost you can use a bridge of 1 amp, 100 volt or higher. Capacitors are 4700 uF @25 volt
wow perfect. with that much voltage we can convert it to AC with inverter and run a led tv??
In order to run an inverter not only voltage is concerned but also amper is imported. This small motor can not supply enough power sadly.
Hi ...i want to know that can i use a microwave motor??
yes but voltage of those motors is very high
what should i do then? i want to use that motor with constant voltage
hello.. how did you get the values for the capacitors? i mean is there a formula for the uf needed?
the values are arbitrary, bigger caps will store more energy.
How to identify 8 wires stepper motor 4 phases thank you.
Hi .. this video was awesome but i wondered about the kind of bridge rectifier you used here ... thank you

what is the used resistors and capacitors?

25 V 4700 μF
as for the resistor, I'll take a wild stab at it:
Judging by the colors I'd say it's brown(1), grey(8), brown(1, how many zeros added to the first two numbers), so it's 180 Ω.

The range is 1000 - 4700 uF. You can pick any capacitor from the range.
this would be great to attach to a pushbike. Maybe diodes could limit the voltage to around 13v.

Zahid Majeed Hello,
The bridge rectifier is KBL04, capacitors are electrolytic ones (25 V, 4700 uF). 😊
What is the resistor value that you used with the LEDs? And what is the purpose of the resistor in the circuit? (electronics isn't my area of knowledge...yet) btw great video!
resistor is 1.2 k ohm, it is used to limit the current that flows into the LED
thanks!
I think if you don't regulate the voltage, and spin the stepper fast, the LEDs will expire, followed by the caps.
Motor model number / part no or link plz
very interesting ..!!
Hi.. This is my first time to comment. What is the serial number of the bridge rectifier and capacitor did you use? Thanks and more power.
