Abstract:
1. A rotating machine, comprising: a rotor, rotating around an axis, wherein the rotor comprises a first permanent magnet set and a second permanent magnet set, and the first permanent magnet set is magnetized in a circumference direction of the axis, and the second permanent magnet set is magnetized in an axial direction of the axis, wherein the first permanent magnet set comprises a plurality of circumferentially magnetized permanent magnets, the second permanent magnet set comprises a plurality of axially magnetized permanent magnets, and each axially magnetized permanent magnet is located between two adjacent circumferentially magnetized permanent magnets in a circumferential direction; and a stator set, corresponding to the rotor, wherein the stator set comprises a radial stator member and an axial stator member, the axial stator member corresponds to the rotor in the axial direction of the axis, and the radial stator member corresponds to the rotor in a radial direction of the axis, wherein the circumferentially magnetized permanent magnets and the axially magnetized permanent magnets are arranged staggeredly on a periphery of the rotor, and the axially magnetized permanent magnets are arranged in pairs axially, wherein each two circumferentially magnetized permanent magnets which are circumferentially adjacent have a same first pole arrangement at corresponding portions thereof, and a pair of the axially facing axially magnetized permanent magnets between the two circumferentially magnetized permanent magnets which are circumferentially adjacent have a same first pole arrangement at corresponding portions thereof.
