Window Motor Replication

[Mark]

Hey Ren

I just watched your video on your 8 filar cap pulser and I must say that is one impressive energizer! Totally awesome! Did you make that rotor yourself or have a machinist make it?

Now back to Vader, hows that coil winding going? Any progress?

[ren]

Patience my young Padawan (insert "Force Smilies" here).....soon.

Yeah the rotor on the 8 filar vid is something I had cut for me. Its cut the same way as the coil formers for the window. A dude actually thought my coil formers were rotors at first. Would have been massive if they were.

You can get it done on a cnc machine. Cut a center hole and a circumference to suit. DONT GET IT LASER CUT. CNC router only.

Stuck magnets on myself. Super glue and 2 part epoxy work great on Acrylic.

Ren.....helloooo Rennnn.....

Hey buddy what the hold up? I dont want to hear any excuses I want to see a video.

Anyways how are things going with the coil winding, almost done?

[ren]

Coils done.

It works, but Im not happy with the results using trigger coils. I have ordered some hall sensors for more acute triggering.

So far I have only driven it off 2 of the 15 power windings.

[Mark]

Sorry to hear that, looks even bigger than it did before.

So what kind of results were you getting?

Window motor.

Hi ren,

Very nice Window Motor you have built there. What RPM are you achieving so far with trigger coils? Looking forward to see your results too.

I have built one similar to that (it is still being tested) and am now working on another one slightly different in concept. This one will have 2 rotors, one inside the other with external drive coils (using the same electronic circuit and hall effect sensors as the first model), internal and external output coils plus the inner rotor will spin by magnetic coupling to the external rotor. All the coils (drive and output) will be bifilar like the first model.

Keep up the good work,

Michel

Sorry to hear that, looks even bigger than it did before.

Ooops. Just figured out circuit was wrong, paralleled two resistors, instead of series. Glad to announce its working MUCH better now. I guess it looks bigger now with all the bits and pieces, including the base plate attached, but I assure you, its still the same structure

As far as results, I have had very little time to test it on the bench, but here are some interesting points.

* I can tune it to draw 0 amps (1-5 amp panel gauge). In reality it is probably drawing 50-100ma, it just cant be seen on this gauge. At this speed, with the output directly hooked up to the input (and no cap) it ran for nearly an hour (50min) before I could audibly hear the rotational speed had decreased. The battery was depleted from 12.34 to 12.20 from starting the machine (hogs the amps to get it started) but once tuned to "0" amps it climbed up to 12.34 and when I finished the run (stopped it when I realised it was ever so slowly decreasing speed) the battery was where it started, 12.34v.

* I can measure 10vac on a single wire from an undriven coil at 12v 500ma input.

* @ 24v the rotor speeds up very quickly and has presented some vibrations that will need to be sorted . I think it could be as simple as a balancing, similar to the number I did on the original with the wheel weights. At full speed it hums along, and rumbles like it is an ICE V8 rough idling.

*All the results above are with one of the 15 power windings connected. ALOT more to come.

Michel, Id be interested in any details you care to share regarding your configuration.

Great job Ren, have you taken any RPM readings?

I'm back to work again myself on a new motor. Finally found someone to make my rotors for me. I'm having 4 rotors made up. I will be using at least 2 on a single shaft. My power coil will be sandwiched between both rotors to take advantage of both ends of the coil. I'll be trying to make my own design to replicate the Watson Machine.

Window Motor.

Hi ren,

The first version of my attempt at a Bedini Window Like Motor can be seen in this thread:
http://www.energeticforum.com/renewa...ead.php?t=4161

For the present build, I only have the internal rotor made but I am taking photographs as I go along and will post them in a futur thread documenting it.

Take care,

Michel

[ren]

Sounds good. I remember bumping into that thread before.

@ Mark,

I havent taken any rpm readings yet. I am waiting to build my third circuit for the third coil and then I will do a video.

Outstanding work Ren.....

So what are your thoughts on trigger windings now that the resistors are correct?

Will you still go to hall switching?

I am really looking forward to the video......:-)

Be happy.....

Just wanted to say that is looking AWESOME ren. This is one I've been wanting to replicate for a while. I wanna go big enough that I could generate 2hp. so I can overdrive an induction motor to make an induction generator. Just like rikoff was saying to do when you were building you first one. BTW any guess on the hp? It only takes 1/10th the energy to spin a induction generator. IE a 20 hp induction generator making 9-10kw only requires 2 hp of input to overdrive it.

AWESOME simply AWESOME

[ren]

Thanks guys.

@ TJ, the triggering windings are working fine now. I will still be implementing or testing halls as well, Ive got plenty of room for the circuit to expand.

@ Want Free... No idea on horse power, it would need a decent input voltage for anything significant. I have other avenues to explore besides straight up grunt. But in so saying I have an induction generator on the cards down the track. I should be getting the third circuit completed this week and I will post a low voltage video. I am going to have to track down and rectify the vibration if I want to run it on more than 24v.

Thanks for your interest.

Hi Ren,

The vibrations really mess things up..... I have a large Newman motor but the magnets are large and I have to tape small washers on the sides of the magnet holder to figure out how to balance it.....

I found a local machine shop so maybe I will take it over to them and watch them as they balance it..... so I can see how they do it.....

Good luck with your balancing act....LOL

Ok, here is a preliminary video guys and girls.

I noticed an interesting generator effect that I thought was worth sharing. Early days still, but looking good.

Sorry about quality it looked much better before I compressed it.

Input appreciated.
