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.

Abstract: 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.

Abstract: The invention relates to a motor stator frame having two plates in cast iron; at least one steel bar connecting both plates, the bar having two ends each attached to one of the plates; and each plate in cast iron has at least one orifice receiving an insert in steel, the end of the bar attached to the plate being welded to said insert.

Abstract: A motor stator frame including two plates in cast iron; at least one steel bar connecting both plates, each bar having two threaded ends; and at least one threaded bushing. Where each of the plates has at least one orifice being used as a seat for each threaded bushing the threaded ends of each bar being engaged into the threaded bushings.

Abstract: A part includes a structure and at least one shape memory alloy element that is prestressed and embedded at least in part within said structure. The shape memory alloy is suitable for dissipating the mechanical energy of said structure when it vibrates in a given frequency band.

Abstract: A method to introduce a deliberate mismatch into a turbomachine bladed wheel so as to reduce vibration amplitudes of the wheel in forced response. The method includes a step of determining an optimum value of the standard deviation for the mismatch as a function of operating conditions of the wheel inside the turbomachine, with respect to the maximum vibration amplitude response required on the wheel. The method further includes a step of at least partly placing blades with different natural frequencies on the wheel such that the standard deviation of the frequency distribution of all blades is equal to at least the mismatch value, the mismatch value being determined statistically.

Abstract: Method to introduce a deliberate mismatch into a turbomachine bladed wheel so as to reduce vibration amplitudes of the wheel in forced response, characterised by the fact that it consists of determining an optimum value of the standard deviation for the mismatch as a function of operating conditions of the wheel inside the turbomachine, with respect to the maximum vibration amplitude response required on the wheel, and of at least partly placing blades with different natural frequencies on the said wheel such that the standard deviation of the frequency distribution of all blades is equal to at least the said mismatch value, the said mismatch value being determined statistically.
