Consider a 220 V (line-to-line), three phase, four pole induction motor. The parameters of the induction motor are rs = 200 m, Lis= Ltr = 2.3 mH and M = 34.2 mH. Assume that the rotor field oriented control is achieved with i = 14 A and is = 20 A at 60 Hz. : qs a. Draw a voltage-current vector diagram and calculate the power factor angle. b. Calculate the torque Te when is = 14 A and is = 20 A. Suppose the motor shaft speed is 1740 rpm. qs c. Calculate the mechanical power, Pm = Tex Wr.
