ESC Help Please
 

Hi, I have a Jeti Jes 012 brushed esc.
The main leads coming out of one side has M+ and M-
On the other side the main wires coming out have A+ and A-
I am assuming the M wires stand for motor and the A wires would be to the battery? is that right? What does A stand for?
Thanks

You are right about M = Motor. Also, + = positive (red) lead, and - = negative (black) lead (but I'm sure you knew that already).

I'm just guessing here about the "A" designation, but in the early days of battery powered radios there was an "A" battery that supplied the high (plate) voltage and a "B" battery that supplied the low (filament) voltage to the tubes (valves for you guys in the UK). As you'll notice today there are no "A" or "B" batteries. The closest is the "AA, AAA, & AAAA" batteries. There are no "B" batteries today.

Anyway, back to the subject, I think the "A" designation just means the "power" battery.

Thanks,
Yes the M goes to motor and A goes to the battery. Thanks for the info, that was interesting.
The previous owner of this plane had it wired backwards. I am lucky I noticed it before anything got fried.
It is all resoldered and flying great now.

Fantastic... Happy flying.

"A" acumalator, china man endlish he try to trasslate to endlish.

Ok, I have a set of instruction for a ECS and they call the battery an acumalator which was what they called them in the old days.....

Thanks again for another interesting fact.
Yes it does accumulate voltage, so I can see why they called it that.

Yes, the 'plate' of a vacuum tube was called the 'Accumulator', on a transistor it's called the 'Collector' (no relation to the "C" type battery, though).
