I have a motor with a stall current of up to 36A. I also have a motor controller which has a peak current rating of 30A. Is there any way I could reduce the stall current or otherwise protect the motor controller?
I realize the "right" solution is to just buy a better motor controller, but we're a bit low on funds right now.
I thought of putting a resistor in series with the motor and came up with a value of 150mΩ, which would reduce the maximum current draw to 25A (given the 12V/36A=330mΩ maximum impedance of the motor). Is there any downside to doing this? Would I be harming the performance of the motor beyond reducing the stall torque?
