摘要
目前锂离子电池(LIB)组是井下电能的主要来源,但LIB技术存在一系列缺陷:成本、充电周期的限制、废物处理问题和可能出现的安全隐患。该文着力研究一种井下电能提供单元井下永磁同步发电机。在分析井下外转子永磁同步发电机设计特点的基础上,利用Matlab软件对一台改造后的2500 r/min、600 W的井下永磁同步发电机样机进行了电磁设计分析并得到性能参数。通过函数分析了各个参数和空载输出电压的关系,并对发电机样机进行试验及结果分析。
In current downhole applications, lithium ion battery (LIB) packs are the primary source for e- lectrical power, but downfalls of LIB technology are cost, limitations on charge cycles, disposal issues and possible safety hazards. So this article mainly researched on a downhole permanent magnet synchronous gen- erator (PMSG) to produce power. On the basis of analyzing design characteristic of the outer rotor generation, the electromagnetic design of a reconstructive 600 W PMSG prototype with 2500 r/min was analyzed through matlab, and got the result. Using a function to analyse the relationship between the parameters and the un- loading output voltage of the generator. Through the testing of the prototype, the results verify the feasibility in practice.
