At 3v on the power supply, what is the average amps at 3v, 42-44-45-46-48 timing? Does timing affect amp draw?More timing, more amps? Less timing, less amps?

 

Thanks


Earl Anderson

I’m no gp12 expert just started building gp12 motors but for me my 44 are around 2.75, 45-46 are 3.00 and 48 is around 3.25.

the major factor is not timing but brushes. I resistance check brushes and go with lowest.

I just had the same talk with Beuf 4 weeks ago how most all my OMB and HBB motors draw big amps like 5 to 7 amps at 5V

 

and years ago a very good motor 3 to 3.75 but he said back then we only ran 38deg and now 42-48 and deg jump the amps a bit 

 

but to get those big amps you must have great brushes and springs

5 to 7 is a strong 12.
