AMORPHOUS STATOR, ELECTRIC MOTOR USING THE SAME, AND PRODUCING METHOD THEREOF

摘要

PURPOSE: An amorphous stator having an interconnecting structure of unit division cores, an electric motor using the same, and a manufacturing method thereof are provided to minimize core loss by using an amorphous metal strip for reducing eddy current loss in a high frequency band. CONSTITUTION: A stator(3) comprises a plurality of divided core assemblies(30a-30r) formed of amorphous metal strips and coil wound around a bobbin(33) integrally formed in a plurality of unit division cores(32). An inner rotor(4) includes a plurality of magnets(4a) arranged in a ring-shaped inner yoke(4b). An outer rotor(5) includes a plurality of magnets(5a) arranged in a ring-shaped outer yoke(5b). A double rotor(50) connects the inner and outer rotors to each other. One end of a rotary shaft(7) is connected to the center of a rotor support frame(6) through an involute serration bushing.
