Double air gap-type surface permanent magnet synchronous motor provided with non-magnetic shielding member

A double air gap surface permanent magnet synchronous motor with non-magnetic solid, comprising:

• a first stator configured to include first protrusions formed on a first inner circumferential surface;
• a first rotor configured to include a first outer circumferential surface facing the first inner circumferential surface;
• first permanent magnets arranged on the first outer circumferential surface;
• a second rotor integrally connected to the first rotor to correspond to an inside of the first rotor and configured to include a second inner circumferential surface;
• second permanent magnets arranged on the second inner circumferential surface;
• a second stator configured to include second protrusions formed on a second outer circumferential surface formed to face the second inner circumferential surface;
• and
• a partition wall portion formed at a boundary between the first rotor and the second rotor,
• wherein a first air gap portion of a predetermined space is formed between the first stator and the first rotor,
• wherein a second air gap portion of a predetermined space is formed between the second stator and the second rotor,
• wherein the first permanent magnets include N-poles and S-poles alternately arranged at equal intervals on the first outer circumferential surface, and the second permanent magnets include N-poles and S-poles alternately arranged at equal intervals on the second inner circumferential surface and are arranged in an opposite polarity to the first permanent magnets,
• wherein a number of the first protrusions is the same as a number of the second protrusions, and the number of the first permanent magnets is the same as the number of the second permanent magnets and is less than the number of the first protrusions.
