Something new for builders: The Universal Motor

DreamThinkBuild:

I am not 100% clear on what you are saying.  It looks to me like you are speculating that when a drive coil pulses against a magnet to move it along the track, that the next coil in the series will see that moving magnet and act as a pick-up coil.  I think that you are speculating that the energy picked up by the pick-up coil can be passed along to another coil acting as a drive coil to keep tings moving.

All that you really need to do is move a magent past a pick-up coil and make precise measurements of how how much mechanical energy it takes to move the magnet, and also make precise measurements of how much energy you can extract from the pick-up coil.  You could try changing various parameters and look at your data.  You could do similar tests where you energize a coil and make precise measurements of how much energy you put into the coil and then make precise measurements of how much energy you can get back from the back-EMF spike.  You don't necessarily need to have a fancy rotary/linear motor configuration.  You want to eliminate all the complexities and just strip it down to the bare essentials to make your measurements.

If you did make these measurements they would confirm that there is no extra energy to be found in pick-up coils or beak-EMF spikes.  Armed with that knowledge you could state that all sorts of fancy motor configurations are based on some pretty simple building blocks and then draw your own conclusions.
