I'm not good in math or physics in general. It's hard to me.
In a DC motor which from start to end take 1 unit of time with 1 unit of weight loaded is the same thing than 2 units of time with half-weight.
The reason I ask this is because I have an old car-window motor weak, I want to increase it's torque by halving a bit the gear.
It will have more torque, it will take more time to finish. But, does it consume the same power in the end changing one for another? If yes, I take a better approach.
I'm assuming normal condition with naturals losses everything has.
