The results of the no-load and blocked-rotor tests on a 3-φ, y-connected, 60-hz, 2000-hp induction machine with a stator phase resistance of 0.02 ω are as follows: no-load test: total input power = 11.617 kw line-to-line voltage = 2300 v line current = 26.55 a blocked-rotor test: total input power = 319.22 kw line-to-line voltage = 462.68 v line current = 407.75 a frequency = 60 hz (a) calculate the parameters r1, x1, xm, r’2, and x’2 of the approximate equivalent circuit. (b) draw the equivalent circuit of the induction motor using the parameters from 3(a).

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
