10.1 Introduction
e magnetic noise emitted by electrical machines is a phenomenon generated by the machine itself,
because it directly originates from the radial vibrations of the stator frame produced by forces that act on
the stator iron in the airgap [1]. e torque harmonics due to the electromagnetic torque time variations
can be more disturbing because tangential vibrations can be transmitted to the mechanical load. us, the
analysis of the eects of torque harmonics is all the more complex as it requires to take into account
the characteristics of the mechanical load associated with the considered electrical machine, in particular ...
