I have a follow-up question on the fuse locations.
I have a circuit where I used two g2 24v13 motor drivers Pololu G2 High-Power Motor Driver 24v13 each one connected to a 24V high torque motor (use 0.55A at no load, 3.55 A at max load, and 15A stall current).
And when I started up the motor drivers, one of my 24v13 drivers seemed to have fried or short-circuited itself.
I believe the reason was that the power supply that I connected to the two drivers was a 24V 15A power supply, and so when I tried to start both motors at the same time, they would draw 30A in total from the startup stall current which would be too much, and apparently that was too much for the pololu 24v13 motor driver board as well and it got fried in some way and won’t work anymore.
To prevent something like this from accidentally happening next time, where would you recommend adding fuses (or a relay?)?
Should I add one fuse each between the motor driver and motor? My concern with this is if the connection suddenly disconnects, will that harm the motor itself (I noticed that disconnecting the motor suddenly causes a big jerk in the motor as it halts immediately)? Or also with this method, would suddenly disconnecting them cause some kind of back current surge which would damage the motor driver, since there is a lot of current initially and then suddenly no current?
