HERMETIC COMPRESSOR

PROBLEM TO BE SOLVED: To solve a problem with a conventional hermetic compressor wherein its manufacturing cost is high because a variety of magnets are required according to the number of a motor stacking thickness and, in manufacturing the magnets, a variety of molds are required according to the number of magnets. SOLUTION: By using a rotor 113 in which a permanent magnet 116 divided into a plurality of parts in the axial direction of the rotor 113 in a rotor core 114 formed of a layered electromagnetic steel plate, the rotor can be used for motors with a variety of stacking thickness by combining a plurality of permanent magnets, and the cost of the motor can be reduced.
