Abstract
A magnet embedded rotor configured to provide an improved magnetization ratio of the field permanent magnets is provided. The magnet embedded rotor includes a first annular core in which first permanent magnets are embedded, and a second annular core in which second permanent magnets, which are independent from the first permanent magnets, are embedded. The magnet embedded rotor has a structure in which the second annular core is fitted onto the outer periphery of the first annular core. The first permanent magnets and the second permanent magnets constitute field permanent magnets.
