Abstract

The invention relates to a double-stator magnetic flux switching wind driven generator which mainly comprises an outer stator, a rotor and an inner stator. Wherein the outer stator consists of an outer stator iron core, a permanent magnet, a direct-current excitation winding and a three-phase armature winding; the inner stator is composed of an inner stator iron core, a permanent magnet, a direct-current excitation winding and a three-phase armature winding, a rotating shaft is arranged in the inner stator, the rotor is located between the outer stator and the inner stator and is of a doubly salient structure, and the rotor is composed of a rotor iron core and a magnetic isolation sleeve.A special rotor structure of the double-stator magnetic flux switching wind driven generator can keep the advantages of high power density and high torque density of the hybrid excitation motor, can realize the brushless effect of the generator, remarkably improves the wind energy utilization rate, greatly enhances the power generation efficiency and the power generation capacity, and is particularly suitable for wind power generation occasions such as remote areas or seas.

Description

technical field [0001] The patent of the present invention relates to the technical field of motors, in particular to a dual-stator flux switching wind power generator technology. Background technique [0002] The stator excitation flux switching motor rotor has a simple structure, neither permanent magnet nor winding, high mechanical strength, suitable for high-speed operation, its permanent magnet is located in the stator, easy to take cooling measures, and can effectively avoid irreversible demagnetization caused by overheating of the permanent magnet , the stator excitation flux switching motor has the advantages of high power density, simple structure, good fault tolerance, flexible control, etc., and has been initially applied in the fields of electric traction, aviation, wind power and other fields. However, due to the random change of wind energy in nature, the air-gap magnetic field in the stator excitation flux switching generator is basically kept constant, and it...
