Power Questions

Hi,

I was wondering how much power the old 3 wire motors draw at full power in mA or A. It doesn’t say in the wiki.

And it looks like the PIC uses 62 mA, so we are good there.

Thanks.

I don’t remember where I found the numbers but I show 1.6A stall current in this graph.

As a comparison, a 269 is 2.8A (my number, wiki says 2.6) and a 393 4.8A.

In a “normal”, non-stalled, situation you will be using about 0.5A.

Here is a thread discussing stall current on the 393 motors. Peaked once at 5.2A, but that was without a motor controller in the loop so the 4.8A number sounds just about right after the voltage drop from the MC29.

Cheers,
