OK. I realize this will be a dumb question but please bear with me especially since I've included the ability to accelerate in my Electronic Lead Screw project. A friend and I were discussing bringing a 300 pound flywheel up to speed. Vz=0 RPM, Vf=50 RPM. Reduction drive to the flywheel shaft is 32:1 so final speed of motor is 1600 RPM. Assume we're happy with 5 seconds to accelerate for Tz to Tf. Motor voltage is 12V. We have the mass, we have the velocity, we have the time and motor voltage. The question is what are the calculations to determine how much current the motor will require to create this acceleration? Assuming of course the motor is 100% efficient. We're getting all confused with F=ma and 1/2*a*t^2 etc. What size motor is actually needed to do this? Thanks. John "ELS!
