The invention discloses a permanent-magnet disk type wind generator with double chute stators, which comprises a left chute stator, a right chute stator, a permanent-magnet rotor, a hollow output shaft, a first chassis, a second chassis, a middle component and a control unit, wherein the left chute stator and the right chute stator are correspondingly arranged and fixed on the first chassis and the second chassis respectively, the permanent-magnet rotor is fixed on the hollow output shaft and positioned between the left chute stator and the right chute stator, the hollow output shaft is arranged in central through holes of the first chassis and the second chassis, and two ends of the first chassis and the second chassis are connected through the middle component. The permanent-magnet disk type wind generator with the double chute stators has the advantages of simple and compact structure, low cost, simple and convenient assembly, and wide application range.

Description

technical field [0001] The invention mainly relates to the field of wind power generators, in particular to a skewed slot double-stator permanent disk type wind power generator. Background technique [0002] In the prior art, a typical permanent magnet generator generally consists of a permanent magnet rotor and a winding stator with an iron core or a winding stator without an iron core. The generator has a large aspect ratio and a heavy weight. At present, although there are generators with double stator core winding and single permanent magnet rotor structure, the stator still adopts the traditional lamination straight slot iron core or cylindrical iron core manufacturing process. In order to meet the requirements of low reluctance torque for vertical-axis wind turbine start-up in light wind, the current solution can only use the method of obliquely opening the magnetic steel, so the manufacturing cost of the permanent magnet rotor cannot be reduced. Vertical-axis wind t...

Problems solved by technology

In order to meet the requirements of low reluctance torque for vertical-axis wind turbines to start in the breeze, the current solution can only use the method of slanting open magnets, which cannot reduce the manufacturing cost of permanent magnet rotors

Vertical-axis wind turbines with traditional structures cannot be flattened and disc-shaped, and use a solid output shaft. It is difficult to equip vertical-axis wind turbines with the particularity of floating assembly of windmills and generators; it cannot reduce the impact of generators on wind power The influence caused by the aerodynamic force of the power generation system, the noise is large
