ABSTRACT:
An automotive electric machine provided with: a stator; a rotor, which is rotationally mounted coaxially to the stator and inside the stator to rotate about a rotation axis; a shaft, which is rotationally mounted about the rotation axis, supports the rotor, and is hollow inside so as to have a longitudinal, central cooling channel filled with a cooling fluid; at least one pushing element, which is arranged inside the cooling channel, is integral with the shaft to rotate with the shaft itself about the rotation axis, and is helical-shaped to define at least one worm which extends within the cooling channel along the rotation axis to push the cooling fluid along the rotation axis due to its rotation.
