This motor includes a frame defining an inner space (VI) in which a rotor, a stator and a fan are housed, the frame comprising an a first opening placing the inner space (VI) of the frame in fluid communication with the outside of the frame, a second opening placing the inner space (VI) of the frame in fluid communication with the outside of the frame along a radial axis (R) substantially perpendicular to a rotation axis (X) of the rotor. The fan being arranged near the second opening and being configured to create a flow (F) of a gaseous fluid, a first acoustic attenuation device is housed in the second opening so as to partially close the second opening.
