Torque-Slip Characteristics in Induction Motor — Lesson 5

This lesson covers the concept of torque-slip characteristics in three-phase induction motors. It explains how to calculate the slip at which maximum torque occurs using the equivalent circuit of the motor. The lesson also discusses the application of the maximum power transfer theorem in this context. It further elaborates on how to calculate the maximum torque and the value of the slip at which it occurs. The lesson concludes by explaining the practical implications of these calculations, particularly in relation to the operating speed of the motor under no-load conditions.
