Abstract:
An electric motor with a stator that is formed of a plurality of distinct laminations. Each of the distinct laminations has a radially inner lamination edge, which borders a rotor aperture configured to receive a rotor therein, a radially outer lamination edge and a plurality of cooling apertures formed there through that are disposed radially between the radially inner and outer lamination edges. Each cooling aperture in a lamination forms part of a separate and distinct cooling channel that extends helically through the laminations about a rotational axis of the electric motor.
