I was only really thinking in terms of torque. I have 26Nm per magmotor at stall, using the best one they supply (S28-400). the two motors gives me 52Nm of torque (in theory), once geared down, i have 628Nm total torque (at stall with a 12:1 ratio). If i have four of these motors, i will have 1256Nm at stall.
I guess im being a bit greedy, but i want stuupid ammounts of torque and a relatively fast travle speed to maximise ramming impacts. If i use four motors (when i have the cash to by two more that is
) then i could easilly put out the 628Nm of torque (similar to the 2 motor set up) but run the robot at a higher speed as well.
I guess this will demand more juice from the batteries and also require larger ones, thus increasing weight. But if its possible and then i might give it a shot. I dont want to meet a heavy/super heavyweight with more power than me if i cna help it.
I want to use the four motors in a differential steering set up, but dont know quite how to wire this up to a speed controller which would normally do 2 motors, maybe i would need two speed controllers, but i cant find alot of info about it.
On a final note i guess i would need two ESC in order to share out the current of the motors and avoid burn out?
Hope that all makes sense
