METHOD OF MANUFACTURING A LINE START PERMANENT MAGNET ELECTRIC MOTOR

摘要

The present invention relates to a line start permanent magnet motor (1) having asynchronous properties at start-up and synchronous features in continuous operation, the rotor (3) of which comprises a core (4) formed of magnetic steel rotor laminations (L), more than one magnet (5) embedded in the core (4), more than one conductor bar (8) and end ring (10, 110) formed by injecting aluminum into the rotor slots (7) and at least one end ring (10, 110) produced separately to be mounted on the core (4) afterwards and wherein the displacement of the magnets (5) is prevented.
