F.2 Torque Gain
Where P_base = Rated Motor Power (W) (1HP = 746W)
W_base = Rated Full Load Speed (rpm)
Ifl = Rated Motor Current (rms)
Im = NL Stator Current (rms)
Nm = ft-lbs. ∗ 1.35582
K_torq = (Nm/Amp)
The torque producing component of the full load current, Iq, in the above equation is:
F.3 Stator Inductance

= Stator Leakage Reactance (ohms)
X
2
= Rotor Leakage Reactance (ohms)
fo = Rated Motor Frequency (Hz)
