摘要
根据电梯外转子同步电动机实际结构提出了一种新型等效磁路模型,推导出电磁计算方程,特别地,精确计算了近极槽组合产生的齿顶部漏磁通。用Maxwell2D软件进行有限元分析并验证了此等效磁路模型准确性及可靠性。
According to the actual structure of outer rotor permanent magnet synchronous motor for elevator, a new equivalent magnetic circuit model is proposed in this paper.The electromagnetic calculation equation of outer rotor permanent magnet synchronous motor is deduced. In particularly, the leakage magnetic flux in the top of tooth at the combination of the near pole slot is calculated based on this model. The accuracy and reliability of the equivalent magnetic circuit model is verified by using Maxwell2D software for finite element analysis.
