ELECTRIC MOTOR, HERMETIC COMPRESSOR, AND REFRIGERATING CYCLE DEVICE

摘要

An electric motor is equipped with: a cylindrical stator having a stator iron core and a stator winding wound around the stator iron core; and a rotor provided inside the stator so as to be freely rotatable. In the electric motor, the stator winding is formed by connecting a plurality of windings in series on a per-phase basis. The windings for each phase consist of both a copper wire and an aluminum wire, and the ratios between the aluminum wire winding and the copper wire winding for the respective phases are made equal to each other.
