Mostly Permanent Magnet Motor with minimal Input Power

[broli]

Your skills at using junk to build things always amazes me, good job .

Concerning the motor though I believe simple induction would kick in. The coil is moving back and forth through a field that's first strong, becomes zero and then flips polarity. So I assume that would induce a back emf in the coil.

I'm curious though, and it might be a freudian slip...what if you replaced the magnets with some strong EM's. The reason is so they can induce the same kind of field in the core as the PM's but allow the inner core to move independently. Would the inner core move or remain stationary when the weak coil is energized . If it moves I guess you know what that could mean.

Hi Broli,

thanks for praising my building skills and posting your comments.

"If it moves I guess you know what that could mean"
Sorry, no!... I don't know what that could mean.

Can you please explain in a simple way.

Thanks for sharing

It's a bit hard to explain. But IF the long inner core moves when the center coil is energized, the field inside of the inner core will automatically "reset" as "new" core material comes in and domains are flipped, this happens because the EM's causing the field are not attached to it so even though the material is moving the field inside is not.
The stationary weak coil will act with a mechanical force on the core and try to pull/push it but since the field never changes the coil, first of all, will not experience a changing flux and second of all the core will never find an equilibrium. So if the inner core is long enough it will be perpetually pulled/pushed.

This is just a hypothesis of course, in reality perhaps the core won't move at all when you energize all coils .

Here are some scope shots.

ADDED
Please note that the test below is to determined how much this mostly magnet motor is affected by the Generator effect. I am not trying to make a Generator out of it.

The first shot is with the motor working on a 1.3vdc input through a 1 Ohm shunt Resistor in series with probe 1 connected across it and probe 2 is across the coil. Both probe grounds are on the same side of the Resistor (standard current and voltage phase setup). Math function is on probe 1 x probe 2

The next shot is to test the motor as Generator, so now the mostly magnet motor coil is connected to a 10 Ohm load with probe 1 connected across the 1 Ohm series shunt and probe 2 is the voltage across the coil (same as above). I'm using the 12vdc motor (attached to flywheel) as primed mover. The input to the 12vdc motor is 380ma @ 12.63vdc = 4.8 Watts to turn it at the speed of the 2nd scope shot below. It looks to me that at that RPM (which is faster then the previous test) the Generator coil is outputting around 0.070 Watts

To me it looks like the mostly magnet motor is not a good Generator considering the amount of input energy needed to the prime mover. However, we need to keep in mind that the 12vdc motor is operating at a much lower RPM then it was designed for, so it could get better. However there seems to be quite a difference.

ADDED
Details on the Coil:
The mostly magnet motor coil has 4 Ohms DC resistance, made of about 0.8mm to 0.9mm magnet wire, wound bifilar connected in series. It has 19 milli Henry when at each ends of the core and 22.5 milli Henry when at center of core. The actual coil size (not including bobbin) opening is 14mm x 20mm and is 17mm wide

As per Stefan Hartmann request (Overunity Forum Administrator)I have made a new video demo.
Stefan says:
a device that can show more vertical lift height in ONE shot , that
does not comply to the energy conservation formular:

m x g x h = 0.5 x C x Voltage^2

will show overunity.

So if you can lift a weight vertically up into the air higher than the stored cap
voltage will tell you, you have a winner....!

Regards, Stefan.

Hi everyone,

I have been working on improving this motor design which I came up with some years back.
The idea of this motor design was to mostly use the flux of powerful Neodymium Magnets we now have, since in a standard magnet motor we would not get a power gain just by upgrading the old ceramic magnets to Neodymium Magnets, as we would also have to add more power to the motor coils to overcome the extra attraction force the Neo Magnets have.
However, in my motor design there is no sticky spot, so the more flux the magnets have the more mechanical power the motor has without changing the input power.

I have made a new video which demonstrates this and also demonstrates a better magnet and cores position which takes full advantage of both Permanent Magnet Poles and of the Electromagnet Poles.

This improvement basically double the mechanical output power of my first design without any increase to the input power.

The video should be self explanatory

Hi Gotoluc and all,

I think that this same concept is what Clemente Figuera used in his overunity generator according to his patent http://www.alpoma.com/figuera/patente_1908.pdf .

Instead of a motor he built a generator with two lateral electromagnets. He fed them with two unphased waves (!!): when the first signal was at maximun the other was at minimun, and then steadily he moved the fields until reaching minimun in the first and maximun intensity in the second. Therefore Figuera moved the two magnetic fields in an opposite way to get an induced current in the coil.

Figuera never stated clearly the pole orientation, but after watching your device I am quite sure that he used like poles facing each other. Figuera called the magnets as "N rectangle" and "S rectangle", but never called them North pole or South pole, but maybe he was hidding the real pole orientation.

I hope this helps to share some ideas between both concepts.
