Beschreibung
Zusammenfassung:	The invention provides a permanent magnet synchronous motor which comprises a stator iron core, a middle rotor, an adjusting rotor, an inner rotor and a magnetic suspension bearing. The stator iron core is provided with a first toothed groove. A drive winding and a control winding are disposed in the first toothed groove. A certain air gap is formed between the middle rotor and each first tooth. The middle rotor comprises second teeth provided with first permanent magnets. The N pole of each first permanent magnet point outwardly, and the S pole thereof points inwardly. The adjusting rotor is located on the inner side of the middle rotor. A certain air gap is formed between the middle rotor and the adjusting rotor. The adjusting rotor comprises third teeth. The bottom end of each third tooth is opposite to the inner rotor. Adjusting rotor windings are disposed among the third teeth. The inner rotor is located on the inner side of the middle rotor. A certain air gap is formed between the middle rotor and the i
