I have some questions regarding the selection of DC motors. (hope this is the right place to post such questions)
My motor driver circuit design can supply a maximum 2A and has over current protection (via utilizing a sense resistor)
So if my max. current is 2A do I select a motor with a maximum running current of 2A?
I'm unsure about stall current, as I understand this is the current drawn by the motor when its trying to turn but can't ie not enough torque to move the load.
Am I right in thinking that my over current protection circuit should kick in if the motor stalls and I should choose a motor with a maximum running current of around 2A to best match my driver circuit?
Ie: a motor with a max. running current (or Max. continuous current) = 1.9A & Stall current = 6A would be well suited?
Also if I use a gearbox attached to the motor this will not affect the electrical properties of the motor, just the rpm/torque trade off right?
Thanks for your help
