RC servo Torque Increase?
I have a DC Servo motor. I want to increase its torque. It has 12volt and max 900mamp current gives 15kgcm torque. I want to remove the tiny DC motor and fix a 5amp 12volt big motor with metal gears. I want to ask " How can I give more current without burning the main SMD circuit board". If I place a battery in parallel to the motor terminals it can burn the circuit. Any ideas ?
