2038 Using Motor As Generators

[abdullahaliyuw]

Impressive explanation! That's what many engineering professors can't do, yet you did it in simpler concept and strategy.

Dude Robert you are awesome!!! I’ve seen tons of videos about diodes and capacitors and still couldn’t really grasp the how and what and you just thought me more in the first 60 seconds of this video than hours of videos dedicated towards teaching all about just diodes and just capacitors! Thanks

[joeviking]

Invaluable information for us novices. My compliments !

[AndreaDingbatt]

Thank you Robert, as always, inspiring and informative!!
(With the added Evil Genius Laugh!!) Brilliant!!❤

Great video! I really love those classic videos that explain electricity principles as well, they did a fantastic job and they also spend a good bit of time with it too.
Re: The basic circuit, for those who plan to use this to generate a specific voltage, the LM2596 DC to DC is a "Buck" style converter, meaning that it will NOT take a 12 volt generator and give you "more" voltage. So, if you want to power something like 20 volts etc, you will want to use a buck-boost type.
Also, don't forget to add a fuse / overload protection into your circuit to protect it from thing like overloads and short circuits.

3:45 and other flashes of that circuit, I'd put the diode first and then the cap, much like the subsequent circuit with transformer.
You want to block any back-driving to the generator, but *then* filter that generator output (regulator's input) to be smoothed via the cap.

Thank you Robert for taking the time to quick explain. U inspire me :) just a single mom in the middle of nowhere building my Utopia. 😊 I have no help and no mentors and you have been helping me along my projects well. Thank you. ❤ Yodi Leclaire

Agreed with most comments here🎉 faboulous explanation that makes ideas click🎉

[justtinkering]

People are always concerned about the voltage drop across the diode and usually recommend a schottky diode because it's around 0.2 volts. What you also can do is connect two of them in parallel because diodes still have resistance, it will increase the current.
I have done this many times and three diodes in parallel is about the limit, as you won't gain anymore current after that.

Awesome information on this! Thank you sir!!!

I used an eight pole induction motor, the generating speed was 740 rpm. To excite the coils I drilled and glued a rear earth magnet into the rotor. It generated up to 90 amps at 24v.

[TheBaconWizard]

I would recommend that one uses a capacitor rated for 25% more than the voltage you think you need, the cheap ones can vary by 10% and it's good to have a bit of headroom anyway.
Higher voltages aren't hard to find and don't affect the price much either.
For anyone not familiar with electronics at-all, you don't need to worry about it if the voltage of your capacitor is vastly greater than the voltage you are working with, there is no ill effect; it's just a tollerance rating. So if the only one you can find is for 400v... fine.

Wow i am very glad i stumbled across this video. I've always been fascinated in wonder how to convert electricity I've never really understood stepson was confident enough to experiment with it because I didn't have an idea of what components I would need where to start with it but I thank you for the video very well explain even for me being a newbie at all this I shall continue to follow along and see what else I can learn thanks Robert 🎉cheers🎉

This reminds me of a pet project I was working on: using a cheap brushed motor, and a couple of cheap op-amps and some in between components, I measured the terminals of the motor as it turned, and fed that into a amps-to-volts converter and then into a voltage integrator and bam! I had a veryyy cheap (albeit not incredibly accurate) rotary encoder from a motor (a motory encoder, as I began to call it)

I realized a couple days ago that while I will never be able to afford even a self build of a home battery, I might be able to afford a small one plus a good sized pile of supercaps. Since it's almost always windy where I'm at it will only be a few hours at night, if anything, where windspeed would be dead calm. If I can keep the house awake for those periods, which are usually low demand anyhow, then it would be rare for me to need to draw from mains. When they call about how I'm not using any power, I will offer to sell them my surplus back if they like. In this way I put the ball in their court because currently you have to request to have the two way meter installed and also pay for it yourself - if they are calling me then I can offer them my power instead of asking for the meter and there's a chance they'll just agree to install it, especially when I tell them I'd rather just give it to my neighbors for free rather than pay for a meter which will take decades (it's expensive, you have to rebuild your whole mains connection to the grid) to return its value, if it lasts long enough to do so.
How to give it away? Put up a charging port at my mailbox that has a light on when there is spare power; give my neighbors a key code to operate it.

[davidbatt]

I find that the easiest regulator to use is a solar charge controller. For a 12 volt battery you can input up to 50 volts into the charge controller

[stevensek]

Just an observation, I believe that you want that diode between the motor and capacitor to stop a back feed. You have it after the capacitor so it would in fact back feed when the motor/generator is stopped.

[shawncalderon]

Funny, I just built your axial flux generator and am adding the capacitors as I watch this!

wish i had my headphones on for this one but i can read lips

I realized my bike has steel spokes. I'm considering setting up a reluctance genartor with the spokes passing by the magnet
