In terms of a torque-speed graph, for an induction motor the torque at 0% synchronous speed is roughly 150x that of(adsbygoogle = window.adsbygoogle || []).push({}); full load torqueand the motor only reaches 100% full load torque at roughly 95% of it's synchronous speed (depending on the rated slip).

If full load torque by definition is the torque required to produce rated power at rated speed then what is rated power?

Also what is actually considered full load? how is the load determined? My understanding is that looking at this graph you can, by knowing how much a load will slow down the rotor speed determine the torque the motor will produce to speed it back up am I wrong?
