ABSTRACT:
Electric machine in which parts subject to magnetostrictive forces are sized and configured in a particular manner. Such parts (1) have radial dimensions that vary along the axial direction. The pads are formed by laminations (12) that are assembled in an alternated arrangement, either individually or by groups, and have differing inner and/or outer dimensions and/or shapes. Such a solution is instrumental in reducing the noise caused by vibrations brought about by the electromagnetic forces generated by the machine.
