No-load and blocked-rotor tests are conducted on a three-phase,wye-connected inductionmotor with the following results. The line-to-line voltage, line current, and total input power for the no-load test are 220 V, 20 A, and 1000 W; and for the blocked-rotor test they are 30 V, 50 A, and 1500 W. The stator resistance, as measured on a dc test, is 0.1  per phase.

(a) Determine the parameters of the equivalent circuit.

(b) Compute the no-load rotational losses.
