Electric Motor Secrets

[Jetijs]

Mark, I could not find any data about the 1n5408 diode speeds and I looked in data sheets of several manufacturers. I don't think that they are good for fast switching. Sure, they will work, but for this purpose we need the fastest diodes we can find. I need something that can handle up to 1000v and is very fast. Unfortunately the fastest diodes can handle lower voltages. I was thinking of using something like MUR4100 (SI-D 1000V 4A/70Ap 75ns), UF4007 (SI-D 1000V 1A/50Ap 75ns) or UF5408 (SI-D 1000V 3A/150Ap 75ns). These are the fastest 1000V diodes I can get in my electronic shop. Any suggestions are welcomed here.

2.8A is what one pair of coils consume (one phase) and that is with the bearings not warmed up yet. If I ran it for a longer time, the speed would go up and the current down. Also this is with not perfectly adjusted timing yet. You can see in the video, that at this one time the motor starts spinning much faster, this is when I turned the second pair of coils ON so the current consumption doubled. So far I am not concerned about the current consumption, we will deal with that later. I will try to measure the HP when both motors will have their axis coupled and the ON times will be chopped to the correct frequency for best recovery.

I have not yet experimented with Tesla pancake coils

LOOKING GOOOOOOD! Jetijs was that 5.4 amps it was using? I thought the 1n5408 were pretty fast diodes, what are you going to use? Have you got any ideas what kind of horse power that will put out. Looks sweet though, excellent work once again.

Off subject, Jetijs have you played around with a Tesla pancake bifilar coil at all? I was wondering if you could run a motor off one.

Sorry guys for the delay . I was SO busy in my day job and my other project to earn money (crisis you know), that I hardly found time to work on my motors. Also I found a problem in the circuit that needed to be fixed, that means getting the circuit out of the box and messing with all the wires again/ That took time. Also I did not want to make any posts without a video of the motor running as I felt that you are tired of my delays already

Anyway. Today I put some life in the motor. I only tested one motor this time and everything ran just great in the first try. I can switch each phase ON and OFF and the "on the fly" timing adjustment works just great. The motor just flew away. I did not measure any RPM's or any other data, just wanted to get this motor running for now. The ON time on the timing wheel is about 50 degree of an ark. For now I just ran this motor on about 12v and it is already so fast (and loud) that I am scared to step the voltage up Also the cooling fan is not attached yet so I did just some small tests. For the recovery on this test I used 1n5408 diodes which are not the best to use for this purpose, I will get some fast switching diodes soon. The vibration of the motor at those speeds is very low, so the balancing is more or less correct.
Here is the video:

Anyway, I am very pleased with the first results

I have to agree with these guys. Jetis you got to post something.

Right

Right???

HOW long shall we wait still?

WHAT'S happening?

Don't You have the least compassion to our unbearable impatience regarding Your so far excellent project?

You could at least submit an empty post? just for chewing on?

::almost dead of waiting::



I hope You ok?

[Mark]

Yea what the F? What he said, we can't wait forever. Is the force with you or not!!! WE NEED AN UP DATE!!!

[StevanC]

Yes, sir! Sorry, sir! Right away, sir!

Amazed!

Loving this thread!

This isn't actually the page I have but it is the patent. The page I have has all the values and parts printed right on the schematic.

Jetijs its a Bedini patent to run motors or even heater elements. Uses a timed pulsed circuit and capisitors. I cant seem to locate it on the net. I printed a copy a while back and have it at work. I'll try to dig it up and tell you where I found it so you can take a look at it. I've been wanting to build it for a while but have been too busy.

[Jetijs]

Just a side note here, Jetijs have you seen and built the Bedini radiant energy pump using the same Mosfet you're using?

What exactly do you mean with "Bedini radiant energy pump"?

[StevanC]

Yes, sir! Sorry, sir! Right away, sir!

i thought so



read ya soon? (job done...)

[Jetijs]

Yes, sir! Sorry, sir! Right away, sir!

Thanks guys
Here's an update:





I put the circuit in an acrylic box and all the wires go to plugs on the aluminum plate, so that it will be like plug'n'play It looks messy with all the wires, but that's ok if everything works well. There are two plugs for each motor. One for timing and other for power. There are four switches so that I can switch each pair of coils on and off. This will allow me to adjust each phase of each motor separately to get the best timing and performance. There are also four red LEDs above the switches, each one indicates which pair of coils is currently running. Those red LEDs are great because with a 3k resistor at 12v they consume only 1mA each and still glow rather bright. The box has an acrylic cover with a hole cut in the middle right above the MOSFET's, this is intended for a cooling fan.
So with a bit of luck, tomorrow both motors will run
If everything goes well, then all I will have left to do is find a good coupler to connect both axis together.
Thanks,
Jetijs

Did You consider a LED feedback for which pole/side is making and which not? You did, didn't You?
So You can (in that YT video we all expect...) show how it makes Q/!Q with the hand, and then let it spin up...
?

And clip the wires together, for crying out loud, with the spring-like plastic thingie or plastic tie-clips or whatever to make it look as pro as possible, once through with troubleshooting ...

Do capture the 1st trial run, just for case...

now, straight to work and make it done, i hate to eat my finger nails so short, yes?


bring it to life!

[Mark]

SWEET!!!! Can't wait to see some testing. Totally awesome!
Just a side note here, Jetijs have you seen and built the Bedini radiant energy pump using the same Mosfet you're using?

Wow. Please let me live in your workshop.
