how do you make an electric motor more powerful? Answered

I am making a battle robot and need to upgrade it to get more torque out of it, in order to lift a 10 pound robot.

Can make electric motor more powerful by: 1) Increasing the number of turns of the rotating coil. 2) using stronger magnet. 3) multiplying the number of coils and commutator segments. 4) winding the coil on a soft iron core; the soft iron core becomes magnetised and concentrates its magnetic field in the coil, this increases the forces on the coil.

Overvolting is the common method to get more power from a motor. It will shorten the life of the motor, and there is a limit on how much overvolting you can do before the motor burns out. Are you using PMDC or a brushless motor?

For more torque add a reduction gearbox. If it is a permanent magnet motor, reducing the airgap between the magnets and armature with mylar sheet or similar will give a little more torque.

Shove more current it. I.e. increase the voltage on the supply. It will tend to get hotter, so keep the usage short. Otherwise you could "rewind" it, but I don't think you'd want to do that. L
