Hi All, I'm hoping you all can help me with what I think should be some relatively simple calculations. I'm looking to determine how large (diameter / weight) of a flywheel a particular AC motor can spin from a stop to full RPM given the torque / HP of the motor. For instance, if I have a 1/3 HP 115v AC motor, which operates at 1725 RPM, I know the torque is ~1.02 lbs/ft. How large of a flywheel can this motor spin safely without risk of over-taxing the motor? Is there a formula to figure this out? Thanks in advance, Nick Edit: This is basically just so I know in advance that I won't cause a motor to overheat / burn out if i try to spin the flywheel on it.
