The Ossie motor

[Jimboot]

My Orzy is doing the grinding thing again the trace below is across the coils of my 2 motors. The top trace is the Orzy. The wave compresses like that when it grinds. I put a stethoscope on the coils & the noise is definitely coming from there. Feels like there is a lot of pent up energy trying to be released.

Also, I see the resistors in the circuits. I see them as something that is slowing things down.

Look at it like this. Without the resistor, the inductor will charge faster and higher. With the resistor it will be slower and less of a field build at the end of the cycle, where the bemf will also be cut down likewise.
Like how much voltage is actually getting across the coils after the resistor during a short pulse? If the reed cant handle it, use bigger ones that can do the job, but dont "limit" yourself with resistors. I think that is kind of going backwards. But thats just me. =]

I said this before about the voltage, why just us 1.5v? Just because Steorn does? If you went to 3v, replace the resistors with diodes in a forward conducting manor through the reeds, and this will be an extra barrier to resist back feed through the reed. Sure there will be a voltage drop, but at 3v, say we get 2.2 at the least. I dont see any problems with that.

Just thoughts that I am going to play with here in a bit.

I have yet to use resistors in my circuits.

I see that. =]  I am just throwing stuff on the plate from stuff I see otherwise. Ideers. =]

Sure. my comment was an FYI. With 3V what sort of battery? Alkaline still? My6v sla at 3v gave no joy. luvyawork
