<p>The invention concerns an electric motor with acoustic insulation of the type of electric motor with external rotor enclosing the stator. The acoustic insulation consists in an acoustic insulation peripheral shield (12) enclosing the outer lateral surface (16) of the rotor made of a material or having a structure providing acoustic attenuation by degenerating sound energy in response to micro-displacements of friction transforming it into heat. Said invention is of interest for manufacturers of electric motors.</p> |
