Hi. I need to control 2 x 12V DC motor from a wheelchair. I dont have access to the datasheet of these motors, so I dont know what is the maximum output current. So my problem is that I cant design my control circuit if I dont know the max current that can flow into my circuit or it can broke. Does anybody know how to mesure/calculate the max current from each motor and is there any component that I can use to control these motors from a PWM signal.
