The general formula relating power, torque and speed is P = T( with P in watts, T in Newton meters, ( in radians/sec. Derive the formula with appropriate constants for P in hp, T in lbf-in, ( in r.p.m. The 3( induction machine in your lab has the following rated values. current = 1.2 A voltages (L-L) = 208 V speed = 1670 r.p.m. power = ¼HP ................
