Question: A 3 7 0 V , 9 8 hp , 1 5 5 Hz , 1 8 pole, Y connected induction motor has the following

A 370V,98hp,155Hz,18 pole, Y connected induction motor has the following impedances, in ohms, per phase and referred to the stator side. The motor is operating with a slip of 5%.(N.B. For this problem, consider the core losses lumped to the rotational losses. Also, the rotational and core losses are for the entire motor.)Induction machine parameters referred to stator sidea) What is the line current, IL? b) What are the stator copper losses, PSCL? c) What is the air gap power, PAG? d) What is the power converted from electrical to mechanical form, PCONV? e) What is the induced torque, Tind? f) What is the load torque, TLOAD? g) What is the overall machine efficiency? h) What is the machine speed, in rps, rpm and rad/s? i) What is the slip at the pull-out torque? j) What is the pull-out torque? k) How much additional resistance (referred to the stator circuit) would it be necessary to add to the rotor circuit to make the maximum torque occur at starting conditions (when the shaft is not moving)? Plot the torque versus speed characteristic of the motor with the additional resistance inserted.(a) Line Current = A(b) Stator Copper losses= W(c) Airgap power= W(d) Converted power= W(e) Induced Torque= Nm(f) Load Torque= Nm(g) Efficiency=%(h) Speed= rps rpm rad/s(i) Pull-out slip=(j) Pull-out Toeque= Nm(k) Additional Resistance= Ohm
