Three-Phase Induction Motors

This course covers the comprehensive understanding of three-phase induction motors. It starts with the basic concept of induction motors, focusing on the definition and implications of 'slip'. The course then delves into the intricate workings of a three-phase induction motor, explaining the application of line to line voltage, the induced voltage, and the concept of flux per pole. It further discusses the equivalent circuit of an induction motor and how it is used to calculate the torque produced by the motor. The course also covers the concept of torque-slip characteristics in three-phase induction motors and how these characteristics change with variations in supply voltage and rotor resistance. Lastly, it introduces the different types of induction motors, specifically focusing on slippering and cage induction motors, explaining their construction and working principles.
