E = Volts; I =Amps; R= Resistance
HP - Horsepower; KW =KiloWatts
Eff = Efficiency; PF + Power Factor
Ohm's Law: E = IR; R= E/I; I = E/R
Synchronous RPM = 120 x HZ/Poles
3oHP = E x I x 1.732 x Eff x PF/746
1oHP = E x I x Eff x PF/746
DC HP = E x I x Eff/746
HP = Torque (lb-ft) x RPM/5250
Affinity law: HP1/HP2 = (RPM1)3/(RPM2)3
3oKW = E x I x 1.732 xPF/1000
1o KW = E x I x PF/1000
DC KW = E x I/1000
KW = Torque (N-m) x RPM/9550
3oAmps = (KVA x 1000)/(E x 1.732)
