  • Electric motor comprising an acoustic attenuation device
    Patent number: 10855139
    Abstract: The electric motor includes a frame defining an inner volume (VI) wherein is accommodated a rotor, a stator and a fan, the frame comprising a first aperture placing the inner volume (VI) of the frame in fluidic communication with the outside of the frame, a second aperture placing the internal volume (VI) of the frame in fluidic communication with the outside of the frame along a radial axis (R) substantially perpendicular to an axis of rotation (X) of the rotor. The fan being positioned in proximity to the second aperture and being configured for generating a gas fluid flow (F), at least one acoustic attenuation device is accommodated in the second aperture so as to partly close the second aperture.
