Make a drawing/design of a block diagram of a synchronous sequential machine with its parts labelled. List the procedures used to draw/design the synchronous sequential machine.

The parameters of a three-phase, 50 Hz, 6-pole, 400 V star connected induction motor are r1 = 0.3 ohm, x1 = 0.5 ohm, r’2 = 0.15 ohm and x’2 = 0.2 ohm. The voltage and frequency of the induction motor is controlled by a power electronic converter (inverter). Calculate the required inverter output frequency and voltage to drive the induction motor load at 0.2 the rated speed of the motor and calculate the current drawn by the motor for that case. The formula for the maximum slip is given below:

Q19. When the magnetic flux per pole of an induction motor is kept constant, can we achieve higher breakdown torque by changing the inverter's fundamental frequency of the output voltage? Give your explanation.
