I am making a bot with 4 motors with a stall current rating of 11.7A. I was using 4 separate motor controllers which has a peak current rating of 20A to control each motor. But when I gave power to the motors in my bot, the motor drivers blew off within a second.
Was it due to the starting peak current of the motors? If yes, then how can I reduce the starting current? If no, then what could be other possible problems and their corresponding problems?
