it's urgent please solve asap P3) A 440-V, 50-Hz, 4-pole, Y-connected, three-phane wound-rotor induction motor has the stator constantparameters of R, = 0.3 0 and X, = 0,90 and constant rotor parameters of R, = 0.6 0 and X, = 0.8 2The rotational loss of the motor is 5% of the power developed. The machine operates at 3% slip in allconditions.a) Illustrate per-phase oquivalent circuit of this induction motor and its power-flow dingram.b) The motor is supposed to carry a conveyer where requires a minimum and maximummechanical torques of 30 and 50 N.m, respectively. The efficiency of the motor at its full-loadcondition is calculated to be 90.78%. We are interested to increave the efficieney of the motorwithout losing much on the mechanical torque. An electrical engincer proposed that if weincrease the rotor resistance or rotor reactance, the efficieney of the motor would be incremed.As a student in electrical machine class, recommend which of the following approach wouldbe more suitable for this conveyer application und justify your answer?1. By doubling the per-phase rotor winding leakage reactance.H. By doubling the per-phase rotor winding resistance.

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end). The end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3.
