This lesson covers the intricate details of loss calculations in induction machines. It delves into the components of loss in an induction machine, including copper losses, core losses, and mechanical losses. The lesson further explains how to calculate these losses using different equations and how to determine the output power and efficiency of a machine. It also discusses the impact of temperature variation on the resistance of a machine and how it affects the stator copper loss. The lesson concludes with an explanation of how to calculate the iron loss in different parts of an induction machine using two different methods.

- The major loss components in an induction machine are copper losses, core losses, and mechanical losses.
- The copper loss is calculated using the I square R loss equation, where R is the dissipating element and I is the current flowing through the resistance.
- Core losses are categorized into hysteresis losses and eddy current losses.
- The hysteresis losses are related to the memory of the magnetic material, while eddy current losses are caused by induced currents in a magnetic material.
- The iron loss in different parts of an induction machine can be calculated using two different methods.
