AC Machines:
We have learnt the fundamental concepts of the transformer, induction motors and special type fractional kilowatt (kW) machines. In the section of transformer you have learned the basic construction, operation principle and testing of the transformers. You have also learnt about the induction motor construction and working principle. Further in the section of induction motors we have focused on the beginning and speed control of induction motors, applications of the induction motors. In the section of single-phase and special purpose motors you have learnt regarding universal motors, servomotors and permanent magnet DC motors.
