Description
本發明係關於風力發電系統的技術領域，特別是指應用於垂直軸風力發電系統之中一種具有外轉子結構的發電機。The invention relates to the technical field of wind power generation systems, in particular to a generator with an outer rotor structure applied to a vertical axis wind power generation system.
電能對於人們的日常生活中已是極為重要的一部分。然而，目前全球的電能大多是透過火力發電產生的；其中，火力發電主要是以燃燒石油、煤、天然氣等化石燃料。眾所周知的是，火力發電的產物將影響大氣層中的臭氧濃度，使得溫室效應更加嚴重。並且，用於火力發電的燃料亦日漸消耗，可想而知的是，若沒有將永續且環保的再生能源發展至穩定且可代替火力發電的話，全球將面臨能源的危機與短缺。因此，改善與提升再生能源的效率與構造以替代傳統火力發電的發電方法，已成為全球相關業者亟欲發展與解決的方向。Electric energy is an extremely important part of people's daily life. However, most of the current global electricity is generated through thermal power generation; among them, thermal power generation is mainly based on burning fossil fuels such as petroleum, coal, and natural gas. It is well known that the products of thermal power generation will affect the ozone concentration in the atmosphere, making the greenhouse effect more serious. In addition, the fuel used for thermal power generation is also increasingly consumed. It is conceivable that if sustainable and environmentally friendly renewable energy is not developed to be stable and can replace thermal power generation, the world will face energy crisis and shortage. Therefore, improving and enhancing the efficiency and structure of renewable energy to replace the traditional thermal power generation method has become an urgent development and solution direction for related industries around the world.
再生能源包括有風力發電、太陽能發電、地熱發電、潮汐發電等。風力發電一種透過電磁感應（Electromagnetic induction）原理來將機械能轉換為電能的發電方法，其主要包含有一轉子及一定子，該轉子與定子上設置有線圈或永久磁鐵。當所述轉子轉動時，會造成通過該轉子或定子之線圈的磁通量產生變化，進而令線圈產生感應電流以達到發電的目的。值得注意的是，根據統計資料顯示，2005年全球風力發電總容量為59GW，到了2015年全球風力發電總容量成長到高達432GW。由此可以得知，風力發電已受到全球相關業者的重視與使用。其中，現有的風力發電機大部分使用內轉子結構；然而，具有內轉子結構的風力發電機具有散熱不易、低轉動慣量、低發電效率、低穩定性以及漆包線使用量多等缺點。Renewable energy includes wind power, solar power, geothermal power, tidal power and so on. Wind power generation is a power generation method that converts mechanical energy into electrical energy through the principle of electromagnetic induction. It mainly includes a rotor and a stator. The rotor and the stator are provided with coils or permanent magnets. When the rotor rotates, the magnetic flux passing through the coils of the rotor or the stator changes, so that the coils generate induced currents to achieve the purpose of generating electricity. It is worth noting that, according to statistics, the total global wind power generation capacity was 59GW in 2005, and by 2015 the global wind power generation capacity has grown to as high as 432GW. From this, it can be known that wind power generation has been valued and used by relevant global players. Among them, most of the existing wind turbines use the inner rotor structure; however, the wind turbines with the inner rotor structure have disadvantages such as difficult heat dissipation, low moment of inertia, low power generation efficiency, low stability, and a large amount of enameled wire used.
