The Ossie motor

[woopy]

Hi Gyula

Thanks for info and encouraging  and it is a pleasure to go on this adventure in the calm and serenity of this thread

and right now i have remount my original 14 Ohms coils on the sandwitch  motor with 2 inverted pole coils     so i have comparison with the same magnet and the same coils congfig as in the Ossiesa basic sandwitch test  ( sorry for the new commers it is something complicated   and please ask for question if necessary) . And of course as i had only 8 of those magnets i could only build a two opposite coils  config.

and the result

so the 2 coil are connected in series and i can run the motor with   only 0,5 ma  ( half a miliamp) at 190 RPM under 3.9 volts.!

really interesting

regards

hi Magluvin

thanks very much for your info

very nice motor

i am a fun of electric motor  from very very small  for indoor RC plane and helicopter to really mighty ones as the ones i uses on my  electric power Ultralght plane ( here a Geiger Motor 13 kw max power ) flying machines.

Hi all

Some more results

Yesterday at 23h  30 i charged my supercap at 4.5 volts and connected it to the 2 coils in serie motor  (no battery at all)  cap at 4,5 volts RPM at 195  and average current at 0.5 miliamps

And this morning after 10 hours the motor still spins at RPM 100 the supercap is at 2.3 volts and the amps across 1 ohm resistor are almost unmeasurable (see pix 1)

For info the 2 coils in serie have 28 ohm resistance and 19.7 mh inductance

pix 2 and 3 shows position and polarity of the magnets

more and more interesting

regards

@Laurent: Looking great!

Hi Magluvin,

Very interesting info on the electric bike, thanks. Recalls a so-called Sumo motor that also has a combination of permanent and electro magnets, here is some info on it, maybe you have heard about it:

The electric motor principle is covered in some Jap and US patents, here is one:
