Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

So I am confused about a a scenario and I hope you guys can hook me up with some explanation.

So I am trying to find the initial force needed for an electric motor to turn. I am not looking for torque or energy just the Newtons just to start from scratch and keep going with the math. with a force X during a certain time with a length Y of the shaft, etc.. I think this is the best way to understand how does the electric motor work. so if I have a the motor connected to a wall plug or running on gas or battery how much force will it take that after we convert it to torqu it will be enough to turn the electric motor shaft.

now lets assume the motor shaft hooks to a small generator through a belt. How much force will the generator need to turn.

I believe the force of the motor should be the sum of both forces or something within those lines. Can you guys tell me how to get the initial force on each, just the force to get it to start turning. I am attaching a little drawing to show the setup.

please use any initial assumptions you want as long as it serves the purpose of finding the initial force.

Thanks alot for your time and help
