The Ossie motor

[Jimboot]

@mags I have alkaline 2Dcells, 1AA & 1 AAA running the motor without resistor at the positive of the battery at 1300RPMS, Good to see this baby speed up With the resistor I get this pulse which is about twice the height. I think I'll get a dynamo next like Ossie was demonstrating. I'm attempting to charge an old SLA but I'm sure I'm not doing it the right way. I'll find out in the morning.

Was messing with the idea of adding some recharge coils to the outside of your pulse coils to gather some volts from the system to get you over the hump in eff.  If this works, you could possibly run many motors on 1 battery.
Below is my vid.  It just shows pulsing a coil, capturing bemf from it and the pickup coil gathering from the first, without diminishing the first bemf. So this should be additional power for you. Even it is little, If the input current does not increase and the rotor does not slow down, its all extree.  I like that word, Extree. My brother uses it. =]

Yikes! Great vid but waaaay beyond my skill level. Thanks tho. I 'll watch it several more times and get back to you. In the meantime I think I'll buy a dynamo Voltage has gone up 0.8 volts in 23mins.  That is nearly 3 times as fast as my D cell without your resistor. Thanks.

For those of you using a HD motor as your bearing I have found a unique anomoly you should try. Stack 1/2" cylinder Neos on the center (stationary shaft) at the top of your disc motor. It causes the speed to increase and current to decrease.

hey Jim
Im not sure what you mean by not using the resistor with the batteries. I hadnt recommended it. Now if you are running the system on a cap alone, then a series resistor I would use. But back emf should bypass the resistor back to the battery. Like shown as earlier.
So are you saying your getting better results with alkaline batteries? Or just that the voltage is rising using smaller batteries like AAA.?

Good going.

Oh yeah

Now if the resistor with the batteries is to make up for reeds staying on longer than wanted, as they would let the coil charge slower, just as the cap would also need, but more ohms, then I would say the resistor could help some.
I have just, myself, been able to reduce my reed timing pretty good with polarizing mags on the reeds and a couple other techniques. I made some vids a bit ago on reeds.
