ELECTRICAL MACHINE WITH STATOR HOUSING HAVING IMPROVED COOLING EFFICIENCY

摘要

The present invention relates to an electrical machine (1) having a stator core (2) and an inner rotor disposed in a space formed inside the stator core (2) and rotatable with respect to the stator core (2) in a manner connected to a shaft, said stator core (2) having a plurality of laminations (3) stamped out in an identical manner and stacked one above the other, each lamination (3) having a plurality of inwardly projecting teeth (4) extending successively along an inner periphery of the stator core (2) to form winding slots (5) that receive windings.
