Brushless Electric Hub Bicycle Motors

[lighty]

I hope I made my description clear in your mind. I don't have any way to send a drawing.

Yes you have. You can draw online and simply share your pictures. For example look here QUEEKY - Draw online! - QUEEKY - draw online

Can you send me some links that show me this in real life? To be honest, I quit reading about Bedini motors about 4 years ago. It was getting complex just in a lab situation. Some were trying to build switching circuits to bring in the recovery battery and then charging the supply battery. You are saying all this can now be applied on the fly in a small Ebike?

@lighty
Thanks for the link. I have a problem with it for two reasons.
1. It barely loads. Slower than dialup connection. It may be because I am behind the Chinese firewall. Many links given in this forum, I can't even access. That is why I am reluctant to start a new thread. I can't always follow the discussion.

2. It seems too complex for me to learn. I will look for a basic drawing tool. I think Google has one? Although now I try to avoid Google, because they track everything you do. If you want to Google search the internet without tracking go here:

Pmm

Hi elias
Everyone seems to be preoccupied to get a self-running PPM. But what good is it if it can not produce real power?

Chris,

I think that it is quite possible to build a permanent magnet motor, because I personally built a small prototype which had a rotor and a piston and I observed the effect that the mechanism was able to produce a one-way force, but the prototype was too weak to produce a self-running PMM.

Your approach maybe one way for achieving this.

A friend of mine has proposed an idea to convert a normal Gasoline Car to a hybrid electric car, and if one can build a permanent magnet free energy generator, and put it in the car the car can run forever without needing to charge again or refuel again. And your approach may lead to this, don't give up! You can even get rid of the Gasoline engine.

Another thing I was wondering was the Hamel spinning disc, which I have verified that the effect it REAL, but the problem seems to be transferring the rotation of the disc to a shaft:

Here is another idea which seems to work:
The Dual Piston Device

Bedini's Magnetic Gate

Chris,

Isn't this design, similar to what you are describing?
Bedini's Magnetic Gate

Thanks for the links.
In my opinion, the Hamel spinner shows the nature of torsion fields in the aether. But, like you say, how do you connect to it to get power? It has to be in delicate balance to work. So, anything connected to it, whether mechanically or electrically, will disturb the balance. The same could be said for all PPM's I have observed.

The dual piston concept has so much mechanical friction, if it works, there won't be anything left to produce power. My design has no friction other than the bearings. I had thought about introducing mu metal shields that rotate out of the way as rotor wants to enter the gate. This would introduce more friction, but nothing compared to the other designs.

The Bedini flux gate is like mine if you do away with the circle of magnets and just have two horizontal bar magnets with like poles facing inward. It will work fine with just two bar magnets replacing the ring. The two small horizontal magnets going through the center of the ring connect together with round neos forming a long rod. Try the experiment I described earlier and you will see what I mean.

I am now 71 years old and my new "toy" is my beautiful wife. After being a bachelor for 22 years, this is a big change for me. Even after I return home later this year with her, I doubt I will have time to work on this concept.
It is really frustrating here not just because of the language barrier. There are no hardware stores, no tools I am used to and I have yet to see an electronic supply store. And, I am in a city of 2.5 million people!

I guess what I am saying is I am "passing the torch" to people like you to do the hands on thing.

Well,
I will, experiment with your design as I finish my current project, and if I get encouraging results I will start a thread, about building your PMM idea into real machines.

By the way, you seem much younger inside!

Thanks, I appreciate that very much.

I will post simple to build proof of principle. Start looking for an old non-ferrous bicycle wheel with good bearings. Acquire a bunch of round neo magnets 3/8 to 3/4 inch in diameter 1/8 to 1/4 thick, and 8 hobby ceramic bar magnets magnetized so that N is on one flat side and S on the other flat side.

I'll buy some tomorrow as I am going get some magnets for my project. And also I have a road bicycle with Aluminum rims, which I can test your concept on.

Ebike

Hey all.
Glad to see someone else working on an Ebike. Been working on one myself for about a year now. I seem to be able to get the thing moving on the bench, but not on the road. Probably is my lack of metal-working skills.
So here is the problem I'm having, don't let this discourage anyone, attaching the motor directly to the wheel seems to be the biggest obstacle to any direct drive. Now I am using a Bedini style motor, capturing back emf, have removed five of six rear gears, and attached a wood plate(I'm a woodworker) in its' stead. The magnets face the coil, 575 winds, on the side of the wheel, not on the edge as in a SSG. There is always the possibility of a separate motor attached to a chain, but then what's the fun in that?

Hi Muttdog

Glad to see you here.

I am having some difficulty in picturing what you are doing. By direct drive, I assume the plate is to hold the motor positioned so the armature can be a friction drive rubbing directly against the rubber tire?

If so, I would try to design the mount so that the tension could be released and the motor pivoted up a little to act as a clutch. That way if the motor fails or the battery dies, you can release the drag of the motor and pedal home.

Maybe just a simple lever with a bungee cord attached would do the job?

Also, I don't know if a Bedini style motor will provide the torque to work this way? My understanding is these motors have sweet spots they want to run at. In a bike, you have to have power over a wide range of rpm. I have never built a Bedini motor, and this is only conjecture on my part.

Aaron,
Wow! Its like you can read my mind. The first motivation to come to this forum, was to try and desulfate with a bedini ssg the lead acid batteries on this Voy scooter. I believe it is a brushed motor as opposed to brushless. the reason i went to this scooter was for local transportation. Which everything is within a mile of my house. Beach, stores ect. The federal law that supercedes all local laws in america says




What this means is very important. Mine went over the 20 mph, it went actually about 30, but nobody ever clocked me. But that really wasnt as important as the savings in insurance, gas, license plates, registrations ect ect. Equaled over what this unit cost in one month. I literally buy one a month and throw them away. And spend less money than i did on my local transportation. So it made alot of sense to go this way.


What my question is, I want to modify this one, but ive been doing other projects, but im still very interested in any information anyone can give me on the regulator and the motor which i believe is brushed. I cannot find a schematic for it nowhere, it is brand new and it is loaded. I want to convert lights, turn signals, ect ect It also has a spot for second batteries which i thought would be great for the bedini concept to increase its range. I also noticed when the throttle is all the way off and it is coasting it does throw energy back into the system somehow. (the lights get brighter) If anyone can get the schematic or explain the process of this one it would help me in the process of modifying it and I would appreciate it. heres some pics of what it looks like :

hub driven scooters

Imhotep, very cool! I like how these synchronicities happen all the time!

I'm leaning towards one of them scooters or another kind probably hub brushless. Couple hundred to about a thousand dollars max for a real wide range of bikes.

But anyway, if it is brand new and you really condition the bats with the Bedini systems or just buy one from energenx, little by little the range will improve. I experienced this with my little 24v scooter...a piece of junk...wheel is so small that turning the handlebars hardly any almost makes you oversteer and fall over every time. Maybe I'm just 3 times bigger than the little kids it was designed for lol. Anyway, I saw the range go up and up on the golf cart at Bedini's that John and Peter were testing the chargers on. If you start with good batteries to begin with I believe all the better.

I really haven't been looking at these scooters until Lighty showed a pic of his and they're really reasonably priced! I was so surprised.

4X3 Motor

I realize I didn/t make myself clear on the round neos when I said a bunch. Since you already have a wheel, make them all the same size that fits on edge inside the wheel. If 3/4 are too big or too expensive, get all 1/2 size, etc.

Hello All

Hi Everyone,


Has anyone ever heard about this motorcycle called the Lectra?
Lectra electric motorcycle, electric motorbike specifications, performance

It kind of puzzles me that the company does'nt exist anymore (I think Zap bought them).I find it interesting that 24volts could achieve 50 MPH and if you look you can even view the electrical schematic.I've also ran accross a NASA sight that has done experiments around 2006 with the switched reluctance motor that suggest's to me anyways that it's a pretty efficient motor and they also made the motor to be bearingless.I would post a link but I'm not sure they would take kindly to that.If anyone wants to find that link try a search under MSN with the search words being "Switched Reluctance Motor".It's worth the viewing just for the pictures and also they were doing super conducting experiments with the motor.I cant understand why more companies are'nt making this motor.Anyways I thought I'd just post some interesting sights.

excellent find ,thanks.
the batteries are the weakest link in this type of transportation ,bedini and others will most likely solve this problem link and we will all benefit as a result and move on from the gas engine (hopefully before the proposed 5-6 or10$ a gallon prices) . i was surprised the partial schmatic was on site. i wish i could find the voy 36volt system schematics. i can reverse engineer ,as i probably will and post mods .
