Abstract :
The authors present a study of the vibratory behaviour of a permanent magnet synchronous motor. Firstly, they made a modal analysis of a structure to determine the first eigenmode. Secondly, they computed the electromagnetic force and the associated shape. Lastly, they investigated the rotor pole shape to reduce vibration
