Hi Jakes. BLDC is missing the sparks that a brushed motor clearly has. The spark is the key, or ‘pulsing’. With capacitors and transistors people try to ‘cope with lenz law’. Theoretically it could work, but some solved it by also using one or several batteries like Bedini. Good luck with your experiments, nice setup you have there
Hans thanks for comments. You are 200% correct. My dream is to put brushes here. And I will. Only then can I do things like amplidyne effects. So 100% upgrade here is to go brushed. I can then also play with different voltages, pwm etc.
back emf, the most misunderstood and misused term in pseudo electronics... all it is is lenz law. eddy currents. its a changing current causing a changing magnetic field that generates an opposing current to the applied one. back, as in reverse, emf. a plain wire, being resistive, flows full current and burns out. it has no Back EMF. as you lengthen the wire, it increases in inductance. wind it into a coil, and inductance increases dramatically. inductance is basically how much Back emf will be produced to counter the applied EMF, in that initial moment when power is applied, or removed. (whenever there is a change in the current) when a potential is first applied, the current tries to change the fastest. it generates the largest opposing back emf at this point. as the field builds, the rate of change reduces, the back emf reduces, and current increases. finally the magnetic field is at its strongest, it has no change at all, and only resistance opposes the applied potential/current. the coil gets hot and or burns out. a motor is a generator. when it is stalled, it is basically a short circuit. the only opposition to the applied current is resistance. they heat up and smoke when stalled. maximum current can flow. maximum magnetic field is produced. when it is running no-load, it is generating a current that is in opposition to the applied current. youre 12V input is opposed by say, 11.5v of back emf. and the 0.5v remainder is what is required to overcome the resistance. minimum current can flow. the magnetic fields are at their weakest. as you load the motor down, it slows down. it generates less BEMF to oppose the applied current. current draw increases. the magnetic field increases. the BLDC is slightly different as its controller doesnt apply the power supply directly to the coils, unlike a plain old brush and commutator. otherwise, they behave exactly the same.
Paradise Lost thanks for this. And yes, you are right. You actually understand BEMF I can see. Thanks for detailed explanation. It is probably better than a ChatGPT explanation;) So with my limited understanding of these things(I only started this project about 8 months ago) I like to test things that I read and see. It is the only way to find new shores. I tried to do things with BEMF, but at this stage I am failing. Mostly because I did not understand it. After many failed experiments trying to do something with it like trickle charge batteries, Im on a new path. Ill share when I get something. If ever you have suggestions for what to use this BEMF(apart from signalling for zvs) Id love to hear it. Thanks again for participating in a positive way.
I agree. Experienced with many failed experiments to do anything with it. I have limited experience and no education in it, so I learn by mistakes. Charging batteries with BEMF was another mistake :) Thanks for commenting.
Does anybody know what ever happened to gerard morin? He just stopped posting videos around the time he was going to china to look at the controller they were making him.
Yes he did stop. Two possible reasons, he passed, or he got the offer! I think all of us is here to get the offer sometime to buy our tech and normally your ass belongs to whom ever has the check book! And your videos. Anthony let me tell you from being in this for a while. The controller is EVERYTHING. Everything. And some or other time, anybody doing this type of machines, lands up at.... where can I find a controller to do this differently.. ;) Thanks for commenting bro!
Well since you said that ill tell you something weird, i commented on the last video he did basically asking for an update and saying it had been a long time with hopes that he was ok and what not, then somebody replied to me about a month later that he had a heart attack and that he died in a coma, when i asked how they knew this they deleted their comment so i looked in to it and could find nothing about it. But you are right about the controller being everything, that resonant frequency is key.
@@rxwhat33 Thanks for sharing! :) It is a pitty. He probably did not know a lot about electricity or electronics, theoretically, but he asked the right questions and he certainly did not play the hand of the monarchs and capatilists getting very very rich on poor peoples basic needs. I do miss him. Good guy!
Hmm... what is pulsed DC if not AC in a square wave... and if you have two DC sources and a common ground... you've just about created a sort of AC in certain situations... isn't that what Edison did? And you've not got a load on the motors... so what's the point here exactly? The motor is meant to run in the horizontal plane as well so you might be getting a sort of flywheel effect as well. Cool stuff to play with, but is the point here exactly? Can you do any work with this setup? Can you spin a full load of laundry?
Pulsed DC is not ac in a square wave. In DC you have a set negative and positive, in DC that alternates. Ac is push and pull, DC square wave is pulsed push.
Simon good comments thank you. I am not educated in electrical engineering. But I would comment that DC is probably the positive wave of AC. In South Africa we have load schedding. It is when the Government switches the electricity off for sometimes 8 plus hours a day. This causes farmers not to be able to pump water. A 2.2kw motor does not work on batteries and solar, at least not with a huuuuuge investment. I am trying to build a pump that can work from batteries, efficiently. So from maybe two to four solar panels you can pump water for km's to animals and growth. So the point is desperate. What have I achieved? I can swing a generator that provides 12v+ and 20 amps worth of DC(rectified AC). With reasonable power usage from batteries. Maybe you can see from other videos I made. You are right about horizontal, tested and I do get more efficiency. My next build will be like that. Thanks for commenting positive value and watching. :)
Katie thanks for checking the video out. Yes, and I can honestly say so far the bifilars did not do anything what so ever. Will keep looking. Such a cool idea ;)
Sorry mate you're misunderstanding a couple things. You can try explain your idea to chat gpt and it'll explain. Also you need to put it on some kind of dyno to determine efficiency
lol, how on earth could "chat gpt" explain anything? it just strings words together. far better to just open a book from about 1930 on electromagnetism.
Lol. I would agree with you. I am not educated in electrical engineering but desperate for solutions. I am very open for any help that you can offer. Thanks for watching and making the effort to comment.

Back emf its not active energy, i dont think these is nothing to get, you will just increase the draw from the mains
I agree. Experienced with many failed experiments to do anything with it. I have limited experience and no education in it, so I learn by mistakes. Charging batteries with BEMF was another mistake :) Thanks for commenting.
Just want to know where and how to tap the back EMF.
You do that across the coils. Thanks for watching. ;)
i like it.sorry mi english is bad. i would[ike to knou more about this.
No problem. let me know what you want to know. There are lots of videos around the washingmachine motors and generators.
best is to get some and try.
I'm always trying to learn. does the engine work and generate at the same time?

I would agree with this. Thanks Mennims.
is that a bifilar coil set up you had implimented there Jakes?
Katie thanks for checking the video out. Yes, and I can honestly say so far the bifilars did not do anything what so ever. Will keep looking. Such a cool idea ;)
from what i understand the bifilar coils have to be just right,ive heard of some people doing twisted pair bifilar coil and having interestng results
