Abstract
An acoustic noise mitigation system for an electric machine includes one or more suspension members. The suspension members may include arcuate members that are positioned between a machine housing and a stator. During operation of the electric machine, the electromagnetic force frequency that is generated by the stator relative to a rotating rotor is able to be absorbed by the suspension members. As a result, acoustic noise generated by the electric machine is reduced.
