Electric Drives Production (PEA)

 

A Brief Introduction

Course banner Copyright: © PEM RWTH Aachen

In the context of electromobility, electric drives are one of the main components of vehicles. As electromechanical converters, such drives are used in all electrified vehicles – from hybrid to purely battery-electric to fuel cell vehicles. The lecture "Production of Electric Drives" (PEA) provides an insight into the value chain of electric motors as well as the adjacent components (power electronics and transmissions). Starting with an understanding of how electric machines work and how to design them for production, the course addresses the manufacture of subcomponents through to the assembly of the complete electric motor. This also includes overarching topics such as economic considerations, quality assurance and assembly planning.
