Abstract
The stator for rotary electric machine comprises a stator frame and a cylindrical magnetic mass inserted in the stator frame, the magnetic mass including a plurality of stacks of compacted magnetic sheets and longitudinal channels uniformly distributed over at least one diameter of the magnetic mass, the channels leading to each side of the magnetic mass. At least three bundles of compacted magnetic sheets are separated by spacers forming two discharge pipes extending circumferentially and radially between the stator frame and a central housing of the stator intended to receive a rotor of the rotary electric machine and communicating with the channels, the stator frame comprising at least two discharge openings connected to different pipes such that a fluid injected on either side of the magnetic mass escapes from the stator via the discharge pipes, the fluid passage section of the discharge pipes being configured to modify the temperature distribution in the magnetic mass.
