This design is the opposite of the Kundel Reciprocating Motor.

http://www.kundelmagnetics.com/

The Kundel features a linear voice coil input that is stimulated electromagnetically to create a mechanical rotary output.

The Floor device is an electromagnetic (if you add a motor drive) to rotary mechanical input converted to a linear mechanical output.

The Kundel appears more advanced, the Floor does not seem to have been previously noticed..

The Floor is a great concept design which demonstrates that a solid scalar field 'free to move' can manifest maximum vector force along a 90 degree axis..

Good stuff!  O0

It's turtles all the way down
Rotary to linear actuators (and the reverse) have been around for centuries in the form of crankshafts, cam actuators etc. Graham can probably name the large variety invented to date.

You can run the images on this page to get a sample.

http://www.mekanizmalar.com/menu-reciprocation.html

The use of magnets eliminates the friction of wear surfaces at the typical points of contact, but due to twisting torsional forces  they  transfer  increased friction to the sliding surfaces and side loading of the wheel bearings. Not sure if there is great advantage in this except in very specialized applications.

If LUC and floor actually have a power gain, it can be  very easily looped by a bit of low friction mechanical linkage from the output shaft to a crank on the driving wheel. This will be the proof of the power gain, a self runner.

I admire their effort and tenacity.

Dear ION.

Yes indeed, I've implemented quite a few too.

In Luc's experiment however, I would perhaps try to implement an electromechanical approach, something on the lines of the oldschool telephone bell ringer?

I built something some years ago that was based on the Irish firms early experiments, the pictures are no longer on the net..... strangely..... It had a bell crank that was driven from the rotor, I think my scale was too small, as usual.
Gut feeling is that Luc's setup might be of a scale to work.   ;)

Cheers Graham.

For proof of gain all that is required is to connect the linear actuator to a crankshaft on the driving wheel. A simple fulcrum with adjustable connection point in between can help to match the output gain to the input load requirement.

Then with a little fine tuning, it should either self run or not. With 60% reported gain, that is way more than is needed to overcome the frictional losses of the added linkage, which should be quite low if properly applied.

A quick test would be to measure the torque required to rotate a small crankshaft on the wheel that matches the "throw" of the linear actuator.

Rotating the wheel by hand at the rim is far easier than rotating the wheel from a small crank on the axle of the wheel. Required torque will go up in inverse proportion to the radius of the crankshaft.

It is good to see that LUC is being very precise in his measurements.

It should be interesting to see how this works out.

Perhaps a face cam would work. Driving onto an arm with a pivot?

Was the linear distance 12.5 mm?  I've forgotten!  :)

With my Gary motor replication I discovered that the action/reaction was non linear so no cam/crank arrangements worked.

Cheers Graham.

I'm wondering if Luc's device could be driven by a small dc motor driving the inside of the wheel via a rubber "gear".  The voltage to drive the motor could be generated by up to four pm/coil generators attached to the linear shafts as they oscillate back and forth.  Since the shafts are running in precision linear bearings, very tight clearances could be used in the pm/coil generators to reach reasonably high efficiency so the main losses would be in the rectification of the pulses feeding a storage cap to drive the motor and the motor itself.  Jus' saying.

I stumbled on this video and wondered if anyone has heard about this device.

MTG (Magnetic Torque Generator)

Link to video: https://www.youtube.com/watch?v=NI2Fwb91PhI

As for my device, I should have a larger version to demonstrate late next week.

I applaud his precise force and torque measurements, too.  Unfortunately, the concept of integrating a force over distance (...or torque over angle) seems to be superfluous to him. 
I've read about his "averaging" of torque, which resembles integration over angle, but is not quite it.

Perhaps you will have more patience to explain this to him...
