In AC motor efficiency, Pout represents what?

Explanation:
Pout is the mechanical power that the motor delivers at its output shaft. In AC motor efficiency, you compare how much electrical power is drawn from the source (Pin) with how much useful work the motor provides as shaft power (Pout). The efficiency is the ratio Pout/Pin, showing how effectively electrical energy becomes useful mechanical work. For example, if Pin is 1000 W and the shaft delivers 800 W, the efficiency is 80%. The other terms describe the input electrical power or the efficiency value itself, not the actual shaft power, so they’re not what Pout represents.
