Give all your answers correct to 4 d.p. A 410 V, 50 Hz, 4-pole, 1,420 rpm, star connected induction motor has the following parameters: stator and rotor resistances are, respectively, 10 and 0.50, and stator and rotor leakage reactance are 0.9 each (magnetising reactance can be neglected). The motor is controlled by simultaneous stator voltage and frequency variation, using V/f control principle. A voltage boost at zero frequency is not used. The motor is supplied from a three-phase voltage source inverter, operated in 180 degrees conduction mode. b) Calculate the machine speed, fundamental component of the stator phase voltage and stator current for load torque equal to 60% of the rated torque and frequency equal to 20 % of the rated frequency (it may be assumed that torque-speed curves are linear and parallel in the operating region). n = Your response Correct response 252+0.1 Auto graded Grade: 0/1.0 rpm V1 = Your response 1 Correct response 47.342722:0.1 Auto graded Grade: 0/1.0 V 14 = Your response Correct response 11.433564:0.1 Auto graded Grade: 0/1.0 А
