Magnetic Wankel Motor

[vidbid]

I tried to copy and paste the simulation for you but the java on this version of linux wont allow me, but it does run in that simulator.

I had some trouble with it, too.

Here's what I did.

See above video.

The whole point is that the recovered energy can be simply put back into the circuit to reduce the input.

Agreed. The circuit may work better to charge a secondary battery or a bank of batteries which could later be swapped (possibly, automatically) with the primary battery.

Daftman has a battery switching circuit that does the job.

The other thing I like about this wankle engine is when we run it in attraction it keeps the flux within the rotor and stator, if we connect the rotor and stator with iron based parts to complete the loop we now have something that we can mount another coil on, using the iron as the core. The varying intensity of the magnetic field could provide another electrical output with little effect on the motor performance. What do you think?

Interesting.

The idea definitely merits experimentation.

Agreed if you want to maximise output, as we all know lead acid batteries respond anomalously to this type of charge giving a real gain.

I have been playing around with this trick on other motors with good results, all of which I feed back to a capacitor across the source. My goal has been making a self runner by using these tricks and then putting a generator on the output shaft. I haven’t succeeded yet, but I am letting people know mods that can get you closer. Running motors in attraction helps with this and the Wankle lends itself to run in that mode.

Time and time again I have looked at this Wankle motor and thought that it could be done.

On closed coils in a motor I achieved 17% into a capacitor from inductive kickback, on the open re gauging coil we could expect much higher recovery, just like a Bedini SSG.

The generation from the case coil is likely to be lower than I have in my motors but that should not be too much of a problem as any gain is good. The greatest change in flux density will likely occur at the same time as re-guaging and I would love to see it on a scope and see what we can get.

I placed 16 small magnets on the inside of a steel pipe, with no gaps between the magnets, and then brought another magnet in close proximity to see what approximate gap would be required to build one of these motors. something strange occurred.

The magnets used were 3.5x5x15mm ceramic. they were placed with their longest sides touching each other. They are of Chinese manufacture and are not exact in their measurements, + or - 0.25mm but I chose the magnets most closely the same size.

The free magnet was strongly attracted to the two magnets on either end of the semi circle and not so strong anywhere else. As I moved the free magnet along the proposed path I noticed the field weakening and strengthening on several occasions, 4 to be exact I was keeping the free magnet as close as possible to the same distance from the fixed magnets (about 6mm). All the positions of maximum strength were equidistant. The positions of minimum strength showed a slight repulsion when the free magnet was brought within 1mm of the fixed magnets.

Is this normal?

Maybe there is more to setting this up than meets the eye.

Here's my observations on Sprain's motor.



Sprain's concept is to use magnetic neutralization on the last magnet on the series of magnets (#5) with the electromagnet (#7).

So the key to this device is (1) using magnets to create motion and (2) using an electromagnet to dampen or cancel the magnetic field of a magnet at a critical timing point.

This idea reminds me what the folks at Gap Power are doing.

Replicator's video: Replication OF TheGAPpower motor. Tried using 1" starship coil...(TEST 24) - YouTube

Variation: Pulse Motor - Gap-Power style setup - YouTube

So there are two places where power can be captured:

(1) From the mechanical output from the device which can be used to drive a generator.

(2) From the fly-back from the coil which can be used to charge secondary batteries.

The main benefit I see with their device is that it looks like it would be easier to build.

PS: I believe the variation design is worth noting:



Pulse Motor - Gap-Power style setup - YouTube

Published on Jul 24, 2012

In this short clip I am testing this new setup according to Gap-Power_com experiments.
The RPM here is 1250, the power is being supplied by 12V 7.5 AHr battery.
The current draw is measured as a voltage drop on 0.1 Ohm shunt resistor and its value is 370 mA maximum. There are 6 N52 neodymium magnets on the rotor, the driving coils are bilfilar in series, 2 in series, 4 Ohms total resistance and about 15 mH inductance together.
A Hall sensor turns on a MOSFET transistor on an approaching magnet to neutralize repelling force from the stack of magnets behind the driving coils that push the rotor at Top Dead Center when the power is off.
In that moment the coil becomes a generator coil as the core (magnetite powder + iron powder + resin) switches polarity and returns much of the energy back to the battery.
This can be seen on the scope trace as the lover curve bump, below the marker line.
It seems to be a very efficient motor, the cores do not heat up, more testing to come...

Yes, I am familiar with the gap motor. I quite like that one.

Looking at the David Scott article we can see the stator magnets appear to be set on a slant, we also see that the iron keeper is close enough to the end magnets on the stator to effect the magnetic field in that position. We also see that the rotor magnet is many times wider than any of the stator magnets which may nullify any cogging like what I just described.

I believe there is more to this than meets the eye.

Here is the gap-power rotary "magnetic neutralization" motor:






Notice the magnets on outer sides of the coils.

Ah uts a different gap motor from the one i know

I'm replicating John Bedini magnetic wankel replication as seen in EFTV16. Does anyone know what timing method or circuit he used in his device? I can get the rotor to continually rotate at about 120rpm using a very crudely build commutator, however on his device i can see nothing of the sort. My guess is that he is using a trigger method similar to that found in his ssg circuit.
