Introduction to Cage Induction Motor — Lesson 9

This lesson covers the different types of induction motors, specifically focusing on slippering and cage induction motors. It explains the construction and working principles of these motors, emphasizing the role of stator and rotor windings. The lesson also discusses the concept of creating poles using stator and rotor currents and the importance of having the same number of poles in both. It further delves into the idea of a balanced two-phase winding in the rotor and how it interacts with a three-phase winding in the stator. The lesson concludes with an introduction to the construction of a cage induction motor, explaining the use of conducting bars in the rotor slots.
