DEK motor with U-coreless coil or Lenz boxing against Lentz

[woopy]

@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

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:

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.
