Output Power (D3L) Product Equation - II — Lesson 6

This lesson covers the in-depth analysis of sizing equations for electrical machines. It explains how these equations are derived considering different flux densities and cuurect density. The lesson also discusses how the output power equation is derived by considering flux density at the air gap, teeth, core, and slot dimensions. It further elaborates on how to maximize the output power by manipulating the magnetic flux density, electrical current density, synchronous speed, and power factor. The lesson also provides a detailed explanation of how the lambda value, the ratio of the inner diameter of the stator to the outer diameter of the stator, influences the design of the machine.
