Is there a different between lenz and lentz? as spelled in the title?

Looking for a clarification.

No it's just a typo.

OK, I've finished my pulsemotor testbed with UCC coil and done some rough programming just to get it running.

The strobe light system works well after putting black and white tape indicators over the magnets. The green sector is the delay between reed switch signal and coil firing. The red sector is the short width pulse into the coil.

I can adjust the delay and the width using a small joystick switch next to the screen.

The motor runs at 1000rpm using about 10mA at 9V.

Now I have to build the BEMF recycling circuit and also program it better so that the timing is relative to the RPM rather than just static delays.

Hi, Thanks Jesus,

The brown board is a cheapo prototyping board as you probably know, I presume you're asking about the blue board: It's a freeduino microcontroller board. You buy them cheaply and you get free programming tools for windows. You just need a USB cable like a printer cable, nothing else to buy. Stacked on top is a nokia LCD screen, again cheaply available.

You program it up using C language.  I will be developing the pulsemotor program so that the user can specify all aspects of timing in tenths of degrees, so 3600 steps per revolution accuracy.

I chose this route because I thought when you're hunting for magnetic anomolies it's good to have reproducible conditions for different coil and mag setups and also good to have an accurate RPM meter. When I evaluate the running I ignore the current draw of the controller unit which is about 110ma at 9V. I just look at the current draw of the coil driver circuit (on the brown board). I'm hoping I might be able to make this current be negative with much more experimenting using Thanes (@crankypants) Perepetia effect.

If you or anyone else wanted to get a controller unit and you dont know C language (yet) then I could give you the pulse motor program via PM and then you just need to click your mouse to program it up. It's a very handy system for researching pulse motors of different configurations.

you can buy the controller and screen board from a UK company here, they have fast and reasonable international shipping:

@Woopy,

I've been thinking about your questions about the UCC. In my mind I don't think in standard drive mode (ala Bedini) the UCC can go overunity in a pulsemotor any easier than a regular solenoid coil. But what attracts me to the UCC is the fact that it is a two phase coil. It has N S S N polarisation as you travel through it. And so I think that maybe on one phase we can apply drive and on the other phase we can short the coil like Thanes perepetia and then maybe coupled with BEMF collection we could go OU. In such a mode of operation the coil would probably start cooling down, a powerful OU motor running on this principle would probably be covered in frost. I have to say though that without a core we won't get enough torque to run a prop. I am thinking that maybe a core could be made for it though, it would be two seperate saddles that U around each circular segment. How this could be manufactured at home I don't know, maybe epoxy loaded with iron powder?

@Jadaro2006 and Broli

yes simply typo   excuse me :-\

@Nievesliveras

thank' for interest and proposition     can you be more precise about the components value  of your circuit ?

@Yucca

very nice job congratulation    wayting for the next results

i like the proposal of using one leg of the UCC as motor and the the second one shorted as BEMF recup or generating "à la Thane"

i have recieved my oscilloscope yesterday and i begin to get used with it    it is surely also THE instrument to investigate how it works


@all

I like very much what is going on with this thread  i learn a lot  on a quite new matter for me   every day         and only for that it is worth

my supposition on  " Lenz boxing  against himself"  is not verified at all untill now  with the UCC   on the contrary it seems to be "Lenz pushing himself"

i have made some test with pendulum magnets traveling through shorted UCC     and the UCC clearly damps the pendulum movement       so the BEMF seems to be  always there :-[

anyway lets go on :)

btw  i have got my copy of  "Peter Lindemann    Electric motor secret    DVD"  and i wondered if it was possible to decrease the  so called "efficiency masking BEMF effect"  by using a long distance between the legs of the UCC  so to say to get   "long  middle torquy stroke pulse "     and not      "short explosive pulse"  ?? 

cheers

Laurent

Thanks @yucca

This is the moment to buy those electronic boards, but at the moment my budget does not allow me to buy them.
Maybe I will regret not have buyed the boards. But I cant  spend money. I am unemployed now.
Another thing is that the price is displayed in other country currency, maybe in dollars is three times the amount.
Thank you anyway.

Laurent, be very careful when scoping pulsed coils with your scope. It is easy to damage an oscilloscope, I once learnt the hard way. I always use a 100x probe when going near pulse motors with my scope.

That´s a shame, the currency is UK pound which is very low at the moment. I´m sure the arduino and freeduino boards will be around for a long time yet so you could get one in the future maybe.

You may still find it useful to put a LED in circuit that lights when the coil is on, this allows you to see where the coil fires relative to the magnet and is great for getting a "feel" for coil mag setups. It´s good to see where the pulse is when you´ve tuned for optimum.

All the best, Yucca.

Forgive me I did not see this question before.
The answer is here:
The resistance can be from 10 ohms to 680 ohms. I usually use 100 ohms and works well.
The transistor could be any NPN. I ususally use 2N2222A.
The diode could be even an LED with the cathode to the base. I usually use 1N4001.

@yucca
I will get some money and buy the freeduino board with the other one, I forgot its name now, soon.

Hello Jesus,

just another question concerning your Battery-Charger :

How is the arragement of the magents ?
Opposite poles - one facing the left - the other facing the right side of the coil ?

Thank you

I think so, but.
That is not my battery charger. That is @woopy's motor with a bediini trigger added the way that is done by the the team at @pirate's thread.
He asked for an idea and I gave him that one. But the magnet arrangement of his motor is explained by him on this very topic a few pages back.

Thanks for your interest.

all !

Any E input - E output meassurements ?
You have (or allmost) finished your prototypes and are pretty neat and precise
so if any Lentz disturbance is occuring  - hopefully there would be some energy output inconsistency...

anyway twiching Lentz anyhow is interesting and may result in E benefits.
