MOOC

Electromechanical conversion II

Description

Electric motors and actuators in general are part of our everyday lives, and can be found in both industrial and consumer applications: automobiles, household appliances, computers and even cell phones use electromechanical systems to create force or motion.

This course covers the operating principles of electric motors, how to calculate their performance and the practical aspects of their use.

The course comprises the following modules:

Rotating field and windings
Synchronous motor
DC motor
Asynchronous motor

For each of these modules, the subject is presented not only from a mathematical point of view, to enable the modeling of complex systems, but also through examples of practical applications and experimental demonstrations.

Instructor

Yves Perriard

Yves Perriard was born in Lausanne in 1965. He received the M. Sc. in Microengineering from the Swiss Federal Institute of Technology - Lausanne (EPFL) in 1989 and the Ph D. degree in 1992. Co-founder of Micro-Beam SA, he was CEO of this company involved in high precision electric drive. Senior lecturer from 1998 and professor since 2003, he is currently director of Laboratory of Integrated Actuators. His research interests are in the field of new actuator design and associated electronic devices. In 2009, he is appointed Vice-Director of the Microengineering Institute in Neuchâtel until 2011. In 2013 the Federal Council has named him the the CTI commission in Bern. In 2014 he is appointed guest professor at Zhejiang University in China. In 2017, the lab is granted by the Werner Siemens Foundation of an amount of 12 millions CHF in order to set up a new Center for Artificial Muscules. Since 2018, he is Expert with Innosuisse, the new Swiss Innovation Agency. http://scholar.google.com/citations?hl=fr&user=V2onuO8AAAAJ https://actu.epfl.ch/news/a-12-million-franc-donation-to-create-a-center-for/
