I have a 10 pound flywheel attached to a 200w motor that has a torque rating of 280Nm that can achieve a 12000 rpm. The gear ratio to the inner axial of the flywheel is roughly 1:1 which is 48mm in diameter for the drive gear and 48mm in diameter for the gear around the flywheel axle.
Also using standard bearings.
There is no load on the flywheel and the only thing the motor has to overcome is the interia and drag of the flywheel.
My question is - how can I tell if the torque is adequate enough and could the flywheel achieve a 12000 rpm itself from the motor?
