The stator resistance of a single-phase induction motor is 1.96 R and the rotor resistance referred to the stator is 3.6 Ω. The motor takes a current of 4.2 A from the 110-V supply at a power factor of 0.624 when running at slip of 0.05. Assume that the core loss is 36 W and that the approximation of Eq. (6.47) is applicable. Find the motor's output power and efficiency neglecting rotational losses.
