USEFUL ELECTRICAL FORMULAE

1.
Input kW = kVA x PF or  Line Amps x Line Volts x 1.732 x PF
1000
2.
Rated kW = kVA x PF x EFF or  Line Amps x Line Volts x 1.732 x PF x EFF
1000
3.
Apparent kVA = 

Rated kW

or 

 Line Amps x Line Volts x 1.732

EFF x PF

 1000
4.
Line Amps = 

Rated kW x 1000

Line Volts x 1.732 x PF x EFF
5.
Rated Torque =  9.55 x Rated kW x 100 in Newton Metres
Rated Speed of Motor (rpm)
6.
Rated kW =  Rated Torque (Nm) x Rated Speed of Motor (r/min)
9.55 x 1000
7.
Rated Slip (%) =  ( Synchronous Speed - Rated Speed ) x 100
Synchronous Speed
8.
Synchronous Speed (r/min) = Frequency (Hz) x 60
Number of Pairs of Poles
9.
Moment of Inertia (J) = GD2  = WR2
4
10.
Convert lbft2 to kgm2 = lbft2
23.75 (Inertia)
11.
Convert Load Inertia from Load Speed to Motor Speed = ( Load Speed )2 x Inertial at Load Speed
Rated Speed
