摘要： The present disclosure relates to a double air gap surface permanent magnet synchronous motor with non-magnetic solid, and particularly, to a double air gap surface permanent magnet synchronous motor with non-magnetic solid, which doubles structures of a rotor and a stator to improve torque performance and has high efficiency and a high power density that satisfy an international efficiency class IE5 of International Electro-technical Commission (IEC) and includes a non-magnetic solid that blocks magnetic fluxes from two permanent magnets so as not to offset mutually. According to an embodiment of the present disclosure, a double air gap surface permanent magnet synchronous motor with non-magnetic solid includes 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.
