Eomys-doc07

This part reviews some key design rules allowing to control noise & vibrations due to magnetic forces, with their advantages and drawbacks. Noise mitigation techniques cover magnetic, control and structural design parameters, but most of the course deals with electromagnetic design modifications as it is the most efficient way to control magnetic noise and vibrations.
