what is the power of a motor
Many people say the following: :With a motor with an output of 50 HP, to convert the HP output into Watts is: 50 HP x 746 Watts/ HP = 37,300 Watts or converting to kiloWatts (kW) = 37.3 kW. A motor of this size probably typically has an efficiency of 90% to 93% (0.90 to 0.93). For our purposes, assume the motor has an efficiency of 92% ( or 0.92).
