Magnetic flux switching type stator permanent magnet double-salient-pole motor with V-shaped or U-shaped permanent magnets

The invention relates to the field of permanent magnet motors, in particular to a magnetic flux switching type stator permanent magnet double-salient-pole motor with V-shaped or U-shaped permanent magnets. The double-salient-pole motor comprises a stator, a rotor, the permanent magnets and an armature winding, and is characterized in that the stator and the rotor are of a salient pole structure, the number of stator teeth is an even number, and the number of rotor teeth is not equal to the number of the stator teeth; the stator and the rotor are each formed by overlapping silicon steel pieces; no winding or permanent magnets are arranged on the rotor; a permanent magnet groove is formed in the position, close to a back yoke, of each stator tooth and used for installing the corresponding permanent magnet; all the permanent magnets on the stator teeth are the same in magnetizing direction, the permanent magnets on every two adjacent stator teeth are alternately arrayed in the N-pole direction and the S-pole direction, and therefore a closed magnetic potential forward-series-connection magnetic flux circuit is formed; all armature winding coils are installed on the stator teeth in a concentrated winding mode, each armature winding coil is installed on the corresponding stator tooth, and all the armature winding coils are evenly arranged on the stator teeth in the circumferential direction according to the phase relation.
