Ok stopped it attached tape. RPMS rising rapidly output from generator 0.5v. Battery steadily rising. Think this needs a vid.

Sorry 4XAA Alkaline. OM Original circuit. 2 Diodes.

Hey Jim
You will have to gear the lil motor to get higher voltages from it. It will need thousands of rpm.
mags

Volts hurt my head - can you measure the amps so we can figure out how many watts the motor is generating?  Please!!!!

hi all

a lot of work but really good results

my first sandwitch motor  works perfectly See pix 1 and 2

Very easy set up i took the coils of the previuos motor and glued them on heavy plastic blocs. The plastic blocs are also glued on a sand paper   so i can place  them on the  basis wood plate where i want and they stay steady. So i can tune the coils at demand  and it is the same for the rotor   so  i can get out the rotor (which is  also mounted on a CD with underneath sand paper )   very practical config to tune every thing very precisely. and allows quick modif


and now to the results


Simply really impressive


in my previous post i could report that      from  the battery at about 4.2 volts i could charge the supercap    (for Gyula  it is a serie of 2    2.7 volt 10 F super cap  = 5.4 volt) up to 4.55 voltr after 8 hours.

this evening i connected the super cap at 3.8 volt at 20.00 'oclock and  3 hours later it is already at 5.31 volts (climbing) and the battery is at 4.12 volts


I made 2 config

1-with the single Hall sensor and circuitery    the Hall circuit consume from itself under a battery at  4,2 volts about 7 milliamp  and when i find the right Hall sensor position the ampmeter shows NOTHING more than the basic circuitery   difficults to say because the amperemeter flickers between 6.4 t0 7.6  but anyway very very low  ?  This shows that without the circuit consumpton  the motor could work with ALMOST NO  current ?  OUCH ?

2- two reeds without electronic  and schottky bridge    across the coils  the best results i could get is not better as  with the electronics   but the scope trace shows an impulse that does not "eat " the induced voltage and the positive BLUE bump of my previous drawing. This is the config of the actual super cxap charging.

3- the rotor of the sandwich is made of a stack of  magnets that i have at disposal . But they are far not so powerfull than my 20 mm neo magnet that i used on my previuos test.   

So i have to order more of those powefull magnets and it is very promising

good luck at all

@Woopy: Really great work!

Frenky

could 'n t prevent me to look at the meters a last time before sleeping

and the battery is always at 4.11 volts and the supercap voltage at 5. 84volts (climbing)

  much above the nominal rated voltage of 5.4 volts

If i suppose that the scope no load max trace is at about 9 6 volts do i suppose that the 5.4 nominal voltage will be pushed away  it's capability   ?

Answers tomorrow  if always alive   HE HE !!
