Description
技术领域Technical field
本发明涉及一种永磁同步风力发电机，尤其是涉及一种散热筋直驱永磁同步单轴承风力发电机。The invention relates to a permanent-magnet synchronous wind-driven generator, in particular to a heat-dissipating rib direct-drive permanent-magnet synchronous single-bearing wind-driven generator.
背景技术 Background technique
国内外各电机厂家研制的直驱式永磁发电机，经过实际运行，有的虽然已经并网发电，但运行还不稳定，可靠性有待进一步验证和提高，特别是，由于电机在电磁、发热及散热分析、支撑结构等方面还存在大量问题，使得电机性能指标较低、温升不可预测，控制特性不好，而且电机过重，运输和吊装十分不便，极容易在吊装过程中造成机械变形。例如，德国的Vensys公司生产和我国某公司引进的1.2MW直驱式永磁发电机采用外转子、内定子的结构，.虽然运行效率高，但自身散热能力很差，需采用内部辅助通风的散热形式，才能正常运行。The direct-drive permanent magnet generators developed by various motor manufacturers at home and abroad, after actual operation, although some have been connected to the grid for power generation, the operation is still unstable, and the reliability needs to be further verified and improved. There are still a lot of problems in heat dissipation analysis, support structure, etc., which make the performance index of the motor low, the temperature rise unpredictable, the control characteristics are not good, and the motor is too heavy, which is very inconvenient for transportation and hoisting, and it is very easy to cause mechanical deformation during the hoisting process . For example, the 1.2MW direct-drive permanent magnet generator produced by Vensys in Germany and imported by a company in my country adopts the structure of outer rotor and inner stator. Although the operating efficiency is high, its own heat dissipation capacity is very poor, and internal auxiliary ventilation is required. Only in the form of heat dissipation can it operate normally.
