交流永磁电机专利分析数据

交流永磁电机专利分析数据主要包括了全球专利数据库中有关交流永磁电机的专利数据，并根据自有算法对专利数据进行了统计，确认重点专利，可用于横向、纵向了解交流永磁电机全球专利数据的变化情况和技术发展趋势，了解各国和各地区企业/个人的技术创新能力、创新水平差异，为企业提供研发合作、技术引进或输出建议。1、采用统计学模型排序、聚类的方法，对专利数据的著录项目进行统计。包括以下：1.数据来源：全球专利数据库；2.数据采集：根据专利的IPC分类号和关键字段，筛选全球专利数据库中的交流永磁电机相关专利，记录著录项目信息，形成交流永磁电机的专利数据库；3.重点专利筛选：专利的重点程度定义由被引用专利数量和简单同族数量确定，即专利重点程度Y=X1+X2，其中X1表示被引用专利数量，X2表示简单同族数量；确认每个专利的重点程度之后，取重点程度值大小排序在前20的专利作为重点专利，标注为是，反之标注为否，具体采用了IF、RANK的组合函数。

The AC permanent magnet motor patent analysis dataset mainly includes patent data related to AC permanent magnet motors from the global patent database. It conducts statistics on the patent data using a self-developed algorithm to identify key patents. This dataset can be used to horizontally and vertically understand the changes in global patent data and technological development trends of AC permanent magnet motors, as well as the differences in technological innovation capabilities and innovation levels among enterprises and individuals from various countries and regions, providing enterprises with suggestions on R&D cooperation, technology introduction or technology output. 1. Statistical sorting and clustering models are adopted to process the bibliographic items of patent data, including the following: 1. Data Source: Global patent database; 2. Data Collection: Screen patents related to AC permanent magnet motors from the global patent database based on IPC classification numbers and key fields, record their bibliographic information, and form a patent database for AC permanent magnet motors; 3. Key Patent Screening: The key degree of a patent is defined by the number of cited patents and the number of simple patent families, i.e., the patent key degree Y = X1 + X2, where X1 represents the number of cited patents and X2 represents the number of simple patent families. After confirming the key degree of each patent, the top 20 patents sorted by the key degree value are selected as key patents and marked as "Yes", while the others are marked as "No". A combined function of IF and RANK is specifically used for this process.
