I am currently building a hobby-weight (5.44kg) robot and will be using 2 x 14.4 cordless driller motors for my wheels.
The thing is I keep reading about high amperages when working with r/c models such as quadcopters BUT when I connect my cordless driller motor to my bench power supply and monitor current draw it never rises above 3.2 Amps even when I try to stop the motor by hand.
Of course in the arena in the event of a stand off I have plastic wheels which will slip so I am not too concerned about stall currents.
I am now left wondering whether I have mis-calculated or whether people make a lot of fuss about high currents for nothing. or do these currents only perhaps really apply to brush-less motors?
