Abstract

The invention relates to an interior permanent magnet type rotor. The rotor includes a rotor core having a plurality of slots formed therein, the plurality of slots having a symmetric longitudinal sectional shape; and a plurality of permanent magnets respectively inserted into the plurality of slots, the plurality of permanent magnets having an asymmetric longitudinal sectional shape, wherein eachof the plurality of permanent magnets includes a top surface part; a bottom surface part formed opposite to the top surface part; and first and second side surface parts connecting the top surface part and the bottom surface part, wherein a first vertical part and a second vertical part, which are in contact with side surface parts of the slot, are formed in the first and second side surface parts, respectively.

Description

[0001] This application claims the priority of Korean Patent Application No. 10-2017-0033199 (filed on March 16, 2017), and the entire content of the Korean Patent Application is hereby incorporated by reference. technical field [0002] The present invention relates to a permanent magnet embedded rotor, a permanent magnet type motor equipped with the permanent magnet embedded rotor, and a compressor equipped with the permanent magnet type motor. Background technique [0003] A permanent magnet type motor (Permanent Magnet type motor) uses a permanent magnet instead of a rotor coil, so it does not need to supply power to the coil and achieves high efficiency. Compared with a standard motor, the longer the operation time, the lower the maintenance cost, and it has recently attracted attention. [0004] Permanent magnet motors can be classified into permanent magnet embedded motors and permanent magnet attached motors. [0005] The permanent magnet embedded motor (Interior Per...
