Content
This course covers the basics needed for the design of an electrical machine. It introduces the different electrical machines, their components, and the main definitions / technical vocabulary needed for the design. It also sheds the light on the different methods of numerical modelling of magneto static systems as well as the finite element approach for the synchronous machine modelling. This course presents the basic analytical method for designing the various parts of a machine while relying on the client requirements (operating voltage, needed speed, geometrical sizing…). It also provides the student with the in depth knowledge needed to simulate the machine's construction using CAD and Matlab software. o Electrical Machines Design – Basics & Background: Overview on the different electrical machines, Machines Specifications, Analytical sizing of an electrical machine, CAD Design of an electrical machine o Electrical Machines Design – Analytical Method for Design: Overview of the winding and the rotating field, Winding layers & Coefficients, Electric machines: materials & components, Design methodology for a PM Synchronous Machine o Project: Design of an electric machine for a given predefined application using Matlab & FEMM 4.2 software
