Magnetic suspension bearing disc hybrid excitation doubly salient wind generator

Abstract

The invention relates to a magnetic suspension bearing disc hybrid excitation doubly salient wind generator, and aims to solve the technical problem that an existing magnetic suspension wind generator system is too complicated in structure, high in energy consumption, inapplicable to small and medium fans and the like. The technical scheme includes that the magnetic suspension bearing disc hybrid excitation doubly salient wind generator comprises a rotor, two generator stators, two permanent magnet rings, three magnetic suspension bearing stators, fan blades and a rotor shaft, magnetic suspension bearing control windings are wound on the magnetic suspension bearing stators, the fan blades are mounted at one end of the rotor shaft, the rotor is mounted at the other end of the rotor shaft, the fan blades, the rotor and the rotor shaft synchronously rotate, the two permanent magnet rings are connected with the two generator stators respectively and further connected with the magnetic suspension bearing stators, the permanent magnet rings are embedded among the magnetic suspension bearing stators and the generator stators, the magnetic suspension bearing stators are uniformly distributed on the periphery of the rotor, the periphery of the rotor extends into the magnetic suspension bearing stators, and air gaps are reserved among the magnetic suspension bearing stators and two planes of the rotor.

Description

technical field [0001] The invention relates to a magnetic-suspension bearing disk-type hybrid excitation double-salient pole wind-driven generator, in particular to a novel magnetic-suspension bearing wind-driven generator capable of working in a low-wind-speed wind energy area and having an extremely low starting wind speed, belonging to the technical field of wind power generation. Background technique [0002] As a clean and renewable energy, wind energy has the characteristics of huge reserves and wide distribution. At present, the main form of wind energy utilization is wind power generation. However, my country's wind resources are limited, how to fully tap the available wind resources, realize wind power generation in low wind energy areas, and carry out efficient research on advanced wind power theory and technology have become key scientific issues in the field of wind power. Due to the large starting torque of traditional wind turbines, the starting wind speed is...
