Mostly Permanent Magnet Motor with minimal Input Power

[hanon]

Hi gotoluc,

Your last videos outperforming a speaker  by almost 10 times is great!!

In this other video at instant 14:19 sec. you state that the current generated while moving (concentrating in its generator mode) has the same polarity as the current that you send to excite the coil.

In case so, this motor would not have back emf, and the generator mode of this device will create a current which will reinforce you input current. Could you elaborate a bit deeperow you tested this feature? I am really interested because of the big consecuences of this fact !!!

I  think that the simplest way is to testing it adding a second small coil outside the first coil. Then with a scope you can compare the applied voltage in the first coil and the generated voltage in the second coil. How did you test it? 

Thanks and congratulation for your great work!!!

Hi Khwartz,

I have next to no schooling. The things I can do are mostly self taught. The experiments I do are my way of trying to learn more in hopes that one day I'll know enough to build a device to be energy independent.

I don't know why but learning all those math equations does not interest me.

I've always been hands on and not into reading patents and theorizing about this or that.

If I find something interesting from the stuff I build that's not commonly done, I share it and hopefully the more knowledgeable ones will find a use for it, suggest different tests or explain in a laymen way why it's not useful.
Anything thrown at me from an academic level is like water on a ducks back.

Lol, no problem Luc,  just do like you feel better to do and sorry if you perceived me too much academic ^_^

Anyway, it was not only for you I was writing, other readers may be interested one or an other day.

Just: one interest of a equations and methodology, is to help to know if we are on the right path or not.

All I wanted to say is that "power" must not be confused with "force", even if it is related with. But I won't bother you again with any "theoretical development"; you did very well until now, so I think to that is good you still continue to do your very own way

Best regards,
Khwartz.

Hi hanon,

back emf could become quite a topic of conversation.
I can confirm the current created by the coils generator effect goes in the same direction as the input current used to move the coil.
How I tested this is simply connect a DC volt meter the the coil and move it by hand in one direction and note the coils polarities. Then, connect the coil to a DC voltage source with the same polarities to see if the coil moves in the same direction as moving it by hand.
It does go in the same direction.
Somehow I don't think this means it has no back emf since I did the same test with a DC permanent magnet motor and the results were the same.

Where this design may have an advantage compared to a standard motor is when the coil reaches the end of the stroke and is switched off.  The coils Flyback goes in the same direction as the next input pulse would needs to go to move the coil in the opposite direction. So it seems the  flyback is working in a complementary way compared to what may be happening in a DC motor.

This is my own observation and would need to be confirmed by the more qualified individuals.

Hope this helps to answer your questions.
If anyone else would like to add or correct anything please feel free to do so, as this would only help many to better understand the working of a motor or an Inductor in motion.

Thanks for your interest and participation

To everyone,

since this topic has been re-opened I may as well share a better performing version of my Mostly Magnet Motor which I compared its pulling force to an off the shelf speaker.

So here is the link to the unlisted video if anyone is interested to see it.

Hi Luc
very excited at your progress.
Perhaps you can make a jig where you can lift up a certain weight so many times per second
= you may be are getting very close to OU, if not there already!
For example, 1 W = .1 kg X m/sec
In your case, for 0.4 W, you will need to lift 500 g by .08 m (8 cm) once a second,
or 500g by 2 cm 4 times per second...

Hi telecom,

last night I was actually thinking that maybe there could be a possibility of OU since I have a newer tandem design that should double what I already have done. So 1 Kg pull with less then 0.5 W should be possible.
I just have to build the thing. However, the main problem is I don't have enough steel lamination core material to build it. So I was thinking to use solid steel just for testing and proof of concepts and wondering if the eddy currents using solid steel would make such a big difference if the coil is only on for a second and traveling less the 10 cm?
Anybody care to comment on that?
