Self-starting permanent magnet synchronous motor and compressor and refrigeration cycle using the same

A self-starting permanent magnet synchronous motor, comprising:

• a rotor;
• and a stator,
• wherein the rotor comprises:
• a rotor core;
• a plurality of slots formed near an outer rim portion of the rotor core at regular intervals;
• conductive bars embedded in the slots;
• a squirrel-cage winding having conductive end rings for short-circuiting the conductive bars at both edge surfaces in an axial direction of the rotor core;
• at least one or more magnet inserting holes arranged on an inner rim side of the slots;
• and
• at least one or more permanent magnets embedded in the magnet inserting holes, and
• wherein the permanent magnets construct field magnetic poles;
• and
• wherein the plurality of conductive bars are arranged in such a manner that in a direction of a center axis of the magnetic poles constructed by the permanent magnets and in a direction of an axis rotated from the center axis of the magnetic poles by 90 degrees, distances from a center axis of the rotor differ.
