Element of a rotating electrical machine, of the rotor or stator type, comprising a plurality of stacks of magnetic sheets each equipped with a tooth comprising notches intended to accommodate electrical windings, and pins arranged between two successive bundles of sheets forming an air-flow duct. A portion of the pins is distributed asymmetrically on the tooth of the stator or rotor sheet with respect to a median axis of the width of the tooth.

A rotor for an asynchronous electrical machine comprising a magnetic ring comprising a plurality of layers of ferromagnetic metal sheets stacked axially and a squirrel cage having a plurality of conductive elements regularly distributed over the periphery of the magnetic ring and each having two opposite ends extending axially beyond the magnetic ring and each connected to a short-circuit crown, arranged axially on either side of the magnetic ring and intended to connect the ends of the conductive elements electrically. The rotor is segmented circumferentially into at least two rotor segments.
