    AC motor load torque calculation

    Ok. Thanks a lot, Dr.D. Now everything is clear to me with a flywheel i.e. it's no load. Averagesupernova, thanks for the wikipedia link. But where is it stated that RPM doesn't depend on a load torque? I know the Equation of motion: dw/dt = (Te-Tl)/J I might be wrong, but doesn't it mean that...

    AC motor load torque calculation

    I was talking about AC induction motor, asynchronous motor in other words. Averagesupernova, I can't agree with you. AC motor speed depends on: voltage, frequency, and a load. Changing any of them leads to a change in speed. As far as I know without a load a motor will speed up until it...

    AC motor load torque calculation

    I think a motor will accelerate until it's torque equals a load torque. And the speed therefore depends on the load (assuming that frequency and voltage remains the same). Below is an illustration. Several motor torque-speed characteristics are shown there. This cylindrical flywheel I...

    AC motor load torque calculation

    Hello! Not sure whether it's a right place to post. My question is from a field of electric drives. I can't figure out how to choose an induction motor for a certain load. Load is a simple cylindric flywheel fitted directly on a rotor. Flywheel has a known mass and dimensions. I know...
