The Thomas Motor

[synchro1]

@Ben,


That would help keep your shop from capsizing!

Hi Gang,

You might want to watch my latest video of my miniature Thomas motor.
Same configuration, very quiet, very fast.  Just a step towards my next
totally different motor, hope it is very fast, very strong, and most of all
interesting!

Yes I know, I could build it in plexiglass, make it pretty but I just happen to have
a bunch of little wooden boxes around that I want to get rid of and using them for the bases for the
motor are ok for now.  Plastic will come later!  Mechanics are from a $10.00 R/C motor that I gutted
to get the rotor and bearings.  For now its a lot easier than turning all that stuff on a lathe.

Hi Ben,

Very cool, I like it and indeed no need for fancy plaxiglass in this experimental phase.

I think that not winding the toroidal core fully up with the coil (but to about 80 to 90% only) helps the operational principle be valid more thoroughly than filling up the full winding area 100%. If I can make out properly, you use a multilayer coil on both cores, maybe forced to do so to help core saturation happen at as a relatively low input power level as possible.
I wonder how the current draw increases in this setup when you apply a mechanical load to the rotor. The prop you are going to obtain will surely make this manifest.

Thanks for showing it!

Hi All,

New version of motor, lots of problems mostly with super strong ball magnet!  But waveform is absolutely clean.  Something is happening in the core/coil with heating and I think it has to do with the ball rotor strength.  Notice large distances between core/hall effect, etc..........lots to learn here......

Also working on Wesley W. Gary magnetic motor.  Patent as written will NOT work.  Don't know if it is intentional but I suspect so.  Fields are reversed in the patent from what they actually are at one point.

Coil had heated/shorted out........
Must make new coils.
