A STATOR FOR AN ELECTRIC ALTERNATING CURRENT MACHINE

摘要

A stator for an electric alternating current machine comprises a stator body (1) adapted to receive a rotor and at least two windings (6, 8, 10) of coils of wires with conductors each surrounded by an insulating sheath running to and fro substantially in the axial direction of the stator body and returning through loops (3) axially outside the stator body. The insulating sheath of the wires comprises an inner layer electrically insulating and surrounding the conductor and an outer protective layer of a material with a high resistance to mechanical influence and quick temperature changes, and loops belonging to different windings bear against each other or are mutually separated by only air and are allowed to come to bear against each other at at least one location.
