Output Power (D2.5L) Product Equation — Lesson 9

This lesson covers the sizing equations of electrical machines, focusing on the (D2.5L) sizing equation. It also discusses the importance of considering rotor geometry, including flux densities at different parts of the rotor core and the actual current density of the rotor. The lesson further explains how to derive power equations based on these factors. For instance, it elaborates on how to calculate the slot area of the rotor and find the flux density values at the teeth, air gap, and back iron. The lesson concludes by discussing the procedure for deriving power equations on the rotor side.
