Abstract A hermetic type compressor comprises a hermetic container in which a compressor mechanism and a motor are provided, and a rotor of the motor is comprised of laminated iron plates in which permanent magnets are embedded, and a main shaft of the compressor mechanism is inserted into the rotor over its entire length. With this structure, even if a centrifugal force is applied to a balance weight at the high speed operation, laminated iron plates of a rotor are not displaced in the radial direction, and an excellent driving state can be kept.
