. . Homework A 440 V, 50 Hz, 6-pole, 50 Hz, Y-connected, three-phase induction motor has 2 2/phase stator resistance and 2.4 2/phase rotor resistance at standstill. Equivalent reactance is 3.6 2/phase. Construct an m-file plots the torque-slip characteristics for slip range (+2 to -1). • From the curve determine the starting torque, and maximum torque. Confirm using analytical solution the values of starting and maximum torque -If the motor runs at 900 rpm while delivering 20 kW useful power and has mechanical losses of 0.5 kW. neglecting magnetizing branch. . ⚫ Calculate: a. Slip, 1 b. Developed power, c. Rotor copper losses F. Developed torque d. Air-gap power. e. Motor Efficiency. • Confirm the torque value using your designed m-file. • Plot on the same graph the torque-slip characteristics from the range (1 to 0) for the rotor resistances 2.4, 4.8, 9.6 2/phase.
