Question

3phase, 50hz, 4 pole, 500v, 1500 rpm, 30Kw, star connected induct motor.

the smoothing of speed is obtained by freq control, with simultaneous voltage control with the help of an inverter.

r1 = 0.2ohm, r2 = 0.27 ohms, x1 = 0.3 ohms, x2 = 0.6 ohms

find:

A) the output frequency of inverter is adjusted to 50hz with the rated torque applied, what RPM will the motor run at?

B) the rated torque is applied and the inverter frequency is reduced to 20hz what will the approx speed of motor be and what should the inverter output voltage be
