无刷双馈电机专利技术发展

Development of patent technology for brushless doubly fed motor

近年来,作为可再生能源的风力发电受到了全球范围的广泛关注,人们越来越重视适用于风力发电的新型电机,无刷双馈电机以其简单的结构,高可靠性,具有异步和同步电机两种电机的综合特点,通过控制激磁绕组的电压和频率易于实现变速恒压恒频发电,是一种适合风力发电运行环境的新型电机。本文主要以DWPI、SIPOABS专利数据库以及CNTXT数据库中的检索结果为分析样本,从专利文献的视角对无刷双馈电机的发展进行了全面的统计分析,总结了与无刷双馈电机相关的国内和国外专利的申请趋势、主要申请人分布以及其转子结构的发展路线做了一定的分析,并从中得到一定的规律。

In recent years,wind power as the renewable energy by widespread concern in the global scope, people pay more and more attention to applicable to wind power as a new kind of motor, brushless doubly fed machine with its simple structure,high reliability,with the comprehensive characteristic of asynchronous and synchronous motor,two kinds of motor,by controlling the voltage and frequency of the excitation winding is easy to realize the variable speed constant frequency and constant voltage power,is a suitable for wind power generation operating environment as a new kind of motor.This paper mainly to DWPI,SIPOABS patent database and CNTXT database retrieval results for the analysis of the sample,from the patent literature from the perspective of the development of brushless doubly fed machine were comprehensive statistical analysis,summarized and brushless doubly fed machine related domestic and foreign patent application trend, mainly distributed in the applicant and the rotor structure of the development route do some analysis, and the obtained certain rules.
