I'm relatively new to worrying about current draw with high power motors, and I just wanted to make sure that this robot I'm building won't blow up or something. I will use the correct rated wire gauge during construction.
Currently, my only concerns are making sure everything is wired correctly and the fuse not prematurely blowing; however, the motor driver has overcurrent protection. The stall current per channel is equal to the sustained rated current per channel. The motors will(obviously) draw less than the stall current, and I don't think it will draw more than 6A in most scenarios. The only time it might exceed the current is during acceleration(which if it is a problem, i will limit in code) and crashes
please ignore how i drew the motor driver, just disregard everything on its left half it will be attached like normal
list of parts used + links:
arduino uno(i dont think i need to link this lol)
adjustable low voltage cutoff
motor(high power 12v variation)
shield/motor driver
battery: sorry, i cant add more links. the specs are on the drawing; just search Zeee 3S Lipo Battery 5200mAh 50C 11.1V RC Batteries with XT60 Connector Soft Case for RC Airplane Helicopter Plane Quadcopter RC Car Truck Boat
the fuse is actually going to be a 20a slow blow fuse right after the positive terminal on the battery. (ignore the drawing) in code, if it hits the stall current, it will immediately lower power to the motors
thank you so much for your help!
