please urgent electrical or mechanical engineer can help? I have 20 hours.I have to finish. Pleaseeee :(
Question 1) A \(380 \mathrm{~V} 60 \mathrm{~Hz}\) two-pole three-phase asynchronous motor has a reverse power factor of 0.80. Stator resistance \(0,200 \Omega\) rotor resistance \(0,120 \Omega\) iron reactance resistance \(150 \Omega\) friction andwind losses \(450 \mathrm{~W}\), iron losses \(1500 \mathrm{~W}\) and stator copper power loss \(1215 \mathrm{~W}\). If the slip is \(5 \%,\) calculate the efficiency of the motor and the shaft moment.Question 2) Three synchronous generators feed 150 of the motors given in the first question. The idle operating...

Can you please answer both (d) and Question - 5.
(d) The equivalent circuit parameters of the motor in (a), at 50Hz, are: R; = 1.50; X;= X, = 40; R = 20; and Xx = 1000 If the motor is to develop its maximum torque at standstill, calculate the output frequency and voltage (RMS) from the inverter, if the air-gap flux remains constant. [6 marks) Question 5 A 4-pole 3-phase, 50 Hz, Y-connected, non-salient pole synchronous motor has the...
