The equation for power consumption of a three phase induction motor is given by the equation:

P = sqrt(3)*V*I*(PF)

Does this differ from the power that is delivered to the motor. For example, if a motor is running at 460 volts, 30 amps with a PF of 0.82, then the power consumption is

P = sqrt(3)*460*30*.82 = 19.6 kW

What is the corresponding power being delivered to the motor? is it the same value? Just want to know if the power being delivered to the motor is different than the power the motor actually consumes.

Best regards,
