The rotary electric machine () comprises a casing (), a stator () comprising a stator body () secured within the casing and comprising first () and second () longitudinal end faces, notches () arranged and extending longitudinally within the stator body between the first and second longitudinal end faces, a coil passing longitudinally through the stator body through the notches and comprising first () and second () coil head assemblies extending in projection from at least one of the first and second longitudinal end faces of the stator body, a first chamber () in the shape of a ring portion arranged around the first coil head assembly and a second chamber () in the shape of a ring portion arranged around the second coil head assembly, the first and second chambers being in fluid communication with one another by the notches, one among the first and second chambers being a coolant inlet chamber and the other among the first and second chambers being a coolant discharge chamber such that a flow of coolant between the first and second annular chambers is forced into the notches while the rotary electric machine is in operation.

Rotary electric machine with improved stator cooling

A stator for a rotating electrical machine comprises a stator mass comprising notches housing the electrical conductors, wherein at least one portion of the electrical conductors, if not the majority, are in the form of a U-shaped pin, and each electrical conductor comprises first and second legs respectively extending axially in first and second notches, each electrical conductor comprising several strands, the strands of the first leg of an electrical conductor being arranged in the first notch in a radially reverse order of the strands of the second leg of the same electrical conductor in the second notch.

Stator for a rotating electrical machine

The invention relates to a flange () for an electrical machine (), said flange being configured to at least partially cover winding overhangs () that form part of the electrical machine (), the flange () comprising a chamber () able to receive a cooling fluid, characterized in that the flange () comprises at least one first orifice and at least one second orifice allowing cooling fluid to enter the chamber () or allowing cooling fluid to leave the chamber (), said chamber () having a profile that compliments that of at least one winding overhang (). Said invention is applicable to motor vehicles.

Flange for an electrical machine

The present invention concerns a brushless electric machine with a rotor having interior permanent magnets, characterised in that the rotor consists of a tubular core (), said core () having N pairs of longitudinal slots () having trapezoidal cross-section, a width Land a length L, where L/L is between 0.25 and 0.35, the two slots () of a pair extending on either side of the median radial plane, at an angle of 7.5&#xb0;&#xb1;1.5&#xb0;, the core having, in the region of convergence of each pair of slots, a longitudinal channel () opening on either side of the front ends of the core ().
