The Ossie motor

@ Jb

Ouups i forgot one coil

my polarity is  - + - + - + - +  that is my coil are in serie  and yours are not in serie Right ?

laurent

My coils are in series.

If you have rise, so it can run steady for weeks...
Can you show this exact setup with values of components? Pls.
Thks,

cheers

Hi Frenky,

If you use the circuit you showed in the schematic on the previous page, and you do not use a diode for rectifying the pulse due to the collapsing flux of coil, then I cannot understand how the pulse from the collapsing field goes back to the battery?
Because when the relay is switched off, the (flyback) pulse is created immediatly but by then the relay contacts are open, they should be open to brake current flow. 

Thanks, Gyula

I was thinking the same thing.  What is happening though is that he is getting the high voltage sparks inside his relay now, instead of in his reed switch like before.  He quickly burnt his reed out this way, and I sort of expect his relay will have much shorter life also.  BUT, the collapsing field is still making it through the circuit across a spark gap now.  So who knows for sure what is really happening as far a battery charge.  But we will certainly take any all data we can get, you never know where that one little nugget of data will come from that changes everything.

@ Future,
Overall though, I just am not sure this is more efficient circuit yet.  By all means, keep going, I do not mean anything negative for sure.  It's just that you are also loosing energy to run that relay that is not recovered at all, you must also take that into consideration.

I'll do a vid but based on Ossie's orig circuit I am currently using
2 x N5408 diodes (non-schottky)
4 X LF1326 coils. (in series)
2 x mini reed switches.
How my motor seems to differ from others:
I buggered up the coil polarity so mine are -++--++-
I have attached the coils using a large self tapping screw which act as a small attraction the mags
I hang my reed switches on or near the screws as I find it easier to tune.
I angle the orientation of my coils so that the + side is closest to the mag.

I have built a schottky circuit but just realised where I made my mistake and how I need to rebuild it.

I am looking forward to getting this one up and running then I'll do a live stream a la Orbo! ( I have my own streaming servers )

Now for the diodes I have in lab  some 1n4007   some BY 550-800  some 1N 5408 and BAT 43 and BAT 48   have you a proposal to make a better Bridge or Half bridge.  And what do you think of Futuristic setup without diode at all and coupling the reed with relay ??

Hi Laurent,

For capturing the most (flyback) pulse from the collapsing flux, the diode must be very fast switching type, BAT 47 and 43 are ok, they have a reverse recovery time t_rr of around 10ns (nanosecond) but they have low forward current and reverse voltage ratings. V_R=40V and I_F=350mA  for BAT47 and these are 30V and 200mA for the BAT43 type.  These ratings are low for such applications here, there is risk for burning them in you circuit with way over a hundred Volt voltage peaks.
Will advise some types tonight.
You other diode types are designed for normal 50-60Hz mains rectification, not fast switching types at all, probably like your beefy bridge.
