Problems solved by technology

[0005] To sum up, the wind power industry has a huge market and promising prospects; however, due to the late start of my country's wind power industry, there are still many problems to be solved. As we all know, the use of wind power generation is inseparable from the development of motors. Big, heavy, unable to generate electricity in a breeze state, and unstable output voltage are the current technical bottlenecks that need to be solved urgently

Embodiment Construction

[0019] The present invention will be further described with specific embodiments below in conjunction with accompanying drawings, see Fig. 1-2:

[0020] A constant-voltage coreless disc-type wind power generator, including a shell consisting of an upper shell 3 and a lower shell 10, a fixed shaft 12 mounted on the shell, and N ironless generator windings 2 connected to the fixed shaft 12, The upper and lower shells are fixed with countersunk screws 28, the magnetic suspension bearing 1 is installed between the fixed shaft 12 and the upper shell 3, and the deep groove bearing 11 is installed between the fixed shaft 12 and the lower shell 10, and the shell can be fixed As the shaft 12 rotates, due to the cooperation between the magnetic suspension bearing 1 and the ordinary deep groove bearing 11, the rotation resistance of the shell is reduced; the inner walls of the upper and lower shells are respectively fixed with the upper yoke 5 and the lower yoke 9 by countersunk screws 4,...

Abstract

The invention relates to a constant voltage coreless disc type wind-driven generator, which comprises shells, a fixed shaft arranged on the shell and N coreless windings of coreless generator connected with the fixed shaft. The interior walls of an upper shell and a lower shell are fixed to upper and lower magnetic yokes as well as upper and lower magnetic steels, respectively; and the fixed shaft and the windings are encapsulated and cured together by means of unsaturated polyester dough molding compounds (DMC). The constant voltage coreless disc type wind-driven generator capable of being started to generate electric power in the state of slight wind is formed by sampling the voltage of the windings of the generator, performing combined switching control to the voltages of windings and outputting constant voltage in the alternating current stabilized circuit. The constant voltage coreless disc type wind-driven generator has advantages of high efficiency, small volume, light weight, stable output voltage, high space utility rate and good overall performance.

Description

technical field [0001] The invention belongs to the technical field of wind power generators, and relates to a constant-voltage ironless disc wind power generator. Background technique [0002] In recent years, with the prominence of global energy resources and environmental issues, especially global climate change, which is characterized by warming, wind power has attracted more and more attention and attention from all countries in the world, and has been obtained with the joint efforts of all countries. With rapid development, the current global installed capacity of wind power has exceeded 100 million kilowatts, and wind power has become an important part of the world's energy. Especially driven by the strong global wind power market, the wind power industry has developed rapidly, and the installed capacity of wind power has increased rapidly. , the capacity of wind power units continues to expand, the safety and reliability of wind power have improved significantly, and...
