Hi everyone!
I am building a robot that carries a drill to make holes in the ground. I have not been able to find similar size/power references regarding how to power the motors. I would like to know how to protect the battery and motor drivers, my specific questions are:
- Where to place fuses.
- If a voltage control is needed or the batteries/motor driver can absorb the voltages produced by
I am running 7 motors all of them 24V all of them brushed DC motors except for the last one
4 for the wheels, 36 amp max
1 for drill, 19.2 amp max
1 that moves the drill up and down, 2.1 A
1 that moves the drill to the sides, 1.5 A -stepper motor
I will use 3 or 4 motor drivers which have overcurrent protection, and over and under-voltage protection.
The battery is a 24V 100Ah Li-ion.
So I have a Battery, Motor Drivers, and Motors. Where the fuses should go?
The actual size of the fuses I will decide when I will be able to test how much current the motors are drawing in the operation or in max load situations.
Is there another element I miss? I heard shunt regulators are used but maybe the motor drivers already can handle them. Is it ok to just connect all motor drivers to the battery directly or maybe restrict max current with a fuse? I am pretty lost if they can share overload for example.. most projects I have found are with only a single motor driver.
Thanks a lot in advance,
Carlos
