0. Induction Motor The induction motor is invented by the scientist Nikola Tesla and it is the most common motor type even today (Around 90%). About 50% of global electric power consumption is due to induction motors. The induction motor has basically two main parts: Stator and Rotor. 1) Stator: Stationary Part The stator is the stationary part of an induction motor like Fig 1-2. It is made up of various stampings with slots to carry 3 phase windings. The windings are geometrically divided 120 degrees separated. It does not require DC current to run the machine. 1. Induction Motor 2) Rotor: Rotating Part 2. :Various Rotors The rotor is the rotating part of the induction motor. The rotor is simply a collection of conducting bars short-circuited by end rings. Its rotation is because of the interaction between the windings and magnetic fields producing a torque around the rotor's axis. There are many kinds of rotors: Squirrel-cage ...
