This thread has been created to discuss and share results of the "Ossie motor" concept.

Maybe we start with some references to the Ossie Motor.

Here is one link.

Maybe someone can provide more?

Question, why is this not just a normal pulse motor?

My replication http://www.youtube.com/user/jimboot#p/u/0/HCj7iT_jdHQ (the motor in this vid is running at 800-1000 RPM not 2500). It ran for nearly 22hours before I stoppped it.
currently running an alkaline D cell has dropped to 1.24 after 24hours running around 300RPM. It is a non-rechargeable as I understand it. Currently working on tuning. Have just built a second motor. I'm focusing on reed switch alignment

Im giving Orbonbon a lil break while I wait for new cores so I broke out the pulse motor. I like these. =]

If they want to convince people that they're onto something other than just another motor, they'll have to give us numbers for input energy (watts) and output energy (watts). Until then, they really are just throwing volts around and volts mean nothing. Is it 1.5 volts at 1 amp (1.5 watts) or 1.5 volts at 5 amps (7.5 watts).

150 volts at .01 amps is the same as 1.5 volts at 1 amp.

Watts is what we need and until they either get volts *and* amps or just watts (which is just volts * amps), it could be 1 watt or 50 watts, but we have no idea.

BTW, they really should go invest in some rechargeable batteries - they're not exactly expensive (what, $8 - less than the magnets cost them, probably).

(edit) Just watched the video and have to say that the rotational speed is... disappointing.

Hello everyone,

I present myself, I am an electronics engineer since a score of year, specialized in the RFID and the house automation. I am interested in renewable energies and the magnetic engines in particular.
That made not time that I am your let us discuss and your experiments on this forum.
I think that the Ossie engine is nothing other than Bidini and thus engine with impulses, whose couple is given by the formula F = B * I * L * NR winds.
B = Flow in teslat of the magnet.
I = current circulating in the reel
L = length of the wire in front of the magnetic field of the magnet
NR = Number of whorl which cuts the magnetic field.

I think that to increase the energy performances of this type of engine, it is necessary:
-   To add in each reel a soft iron core.
-   To increase the length of the wire opposite the magnet.
-   If one does not wish to have an electromagnet, one buckles the iron core as in Orbo.
-   To add more reel to the Stator

Greetings

Your soft iron core won't make much difference. The best you'll do is to double the efficiency of the electromagnet and that's if you had a perfect core (supermendur is better than iron, btw).

You'll find electromagnets with hundreds of pounds of holding force for little wattage input. These are lifting magnets that wrap the 'core' completely around the magnet, creating a low reluctance, high permeability magnetic 'circuit'. Opposite pole magnets (like those found in stators of motors) don't wrap around the same way (though some play a similar game and get very high levels of efficiency) and you'll be lucky to get more than a hundredth of the force that the lifting magnets can get for the same wattage input.

The problem that you'll run into with the iron core (the neo mag grabbing it) will be more problem than it's worth to increase the efficiency of the EM by that small amount. This is why electric motors rarely use ferrous cores - they're more trouble than they're worth.

Solinear ,

The advantage of the solution with a Reel with core or Torus, is that one has two Forces:
- An Attraction force to the low permeability of material constituting the core: Metglas or others.
- A Force of repulsion following the impulse.

The easy way of Ossie is to use the same Reel to generate the impulse and to collect energy due to the rupture of the magnetic field and to hope to reload the Battery.
Precisely, I think that a Orbo engine + Ossie would be more powerful.

There has been some fantastic replications of this motor already. It is very important that we continue down this road. My personal replication is also doing very well, but at this time my coils do not generate a higher voltage than the battery so the battery does continue to decline slowly. I'm waiting for some new magnet wire, and stronger magnets to show up, then I'll get back on track.

To the newcomers to this motor work, there are a few key things to understand. First, the rotation of the rotor is the free energy. In the most simple design, perfectly tuned, a battery runs an air cored pulse motor. A portion of the energy used to pulse the motor is returned to the run battery. A portion of the generating current from the magnets passing the coils is returned to the battery also. And the BEMF that simply occurs due to Lenz Law is also sent to the battery. Adding all this up, with a perfectly tuned motor is supposed to equal or exceed slightly the energy leaving the battery for the initial pulse. In theory, this is how the battery just keeps running and running without going down in voltage. All the while, the rotor is still spinning. Energy can then be extracted from the rotating rotor in many different ways including simple pickup coils.

Now of course this is just a CONVENTIONAL way to explain what is happening, and just for simplicity. But to be honest, if the battery never runs down and the motor still runs, there is nothing conventional about it!

Hi guys.

I would recommend to try this design.
Instead of using half-wave rectifier to pickup negative part of AC wave we could use full-wave rectifier to feed the battery with all induced current.
Below is Naudins scope shot of induced voltage in a coils and my suggested circuit.

Have fun,

I agree. Altho I am a complete noob at all of this. I'll be trialling some of those aircoils with metglas cores. Not sure whether they will get saturated or not but I'll find out.

I'll do some numbers for you tonight. By the way I'm not trying to convince anyone of anything. I'm simply investigating & sharing (open source) my results. I'm not using a rechargeable battery as I wanted to see what would happen if I used a bog standard old battery. So far my 8 year old D cell which had 1.32V at the start of the run is at 1.2V after 35hours of running at 300RPM. The amps are extremely low I know that but I don't have an exact measure yet. I'm simply trying to learn here and hopefully help others with my findings.

I completely agree and have already been playing with the full wave concept. Only problem is, unless I am looking at the circuit wrong, doesn't that short out the battery? Maybe I'll go ahead and test it, maybe I'm looking at it wrong, but I have not done it yet because I thought I may need to use reeds to connect the second half of the full wave so they are not connected when the pulse is delivered?

I'll see if I end up shorting out my battery and give it whirl, maybe I'm looking at it wrong.

Hi.

I see no way that battery would be shortened. I'll make tomorrow some sketchs of current flow in each part of waveform.

Have fun

Frenky

P.S.
I have almost all the parts for this type of motor (even got some 5.5V 1F super caps). Can't wait to start building.

Yeah, I think I may have simply drawn my bridge backwards when I sketched it last week, lol... I see no short in this diagram either. I'll give it a whirl.
