Nettetand fans follow a square law relationship of torque vs. speed. That is, at zero speed, virtually zero torque is required, but the torque requirement increases as the square of the speed (to 100% torque at rated speed) as the load accelerates. Loads of this nature are generally referred to as “Variable Torque” (V.T.). Nettetno relationship between motor inertia and load inertia, except for some very special application and purposes. Torque-Speed Curve The torque speed curve of a load is …
