Motor application formulae
Kilowatts = Torque(Nm) x rpm9550
Torque (Nm) = kilowatts x 9550rpm
Speed
Synchronous rpm = Hertz x 120poles
Percentage slip = (Synchronous rpm - full load rpm) x 100Synchronous rpm
Amps knowing input kilowatts
Amps = input kilowatts x 10001.732 x volts x power factor
Amps knowing output kilowatts
Amps = output kilowatts x 10001.732 x volts x power factor x efficiency*
Amps knowing kVA
Amps = kVA x 10001.732 x volts
kVA
kVA = 1.732 x volts x amps1000
Input kilowatts
Input kilowatts = 1.732 x volts x amps x power factor1000
Output kilowatts
Output kilowatts = 1.732 x volts x amps x power factor x efficiency1000
Efficiency knowing output kilowatts
efficiency* = output kilowatts x 10001.732 x volts x amps x power factor
Power factor knowing input kilowatts
power factor = input kilowatts x 10001.732 x volts x amps
Convert kilowatts to horsepower / horsepower to kilowatts
horsepower = kilowatts kilowatts = horsepower x 0.7460.746
