【摘要】：传统定子永磁型动铁心式横向磁通直线振荡电机因采用定子齿表贴永磁体,其磁通路径为串联结构,因此存在永磁体用量大、材料成本高、维护难度大等缺点,严重阻碍了该类电机的商业化应用。提出一种新型定子永磁型动铁心式横向磁通直线振荡电机,将传统定子齿面表贴的永磁体内嵌于定子轭部。首先对新型拓扑结构及其运行原理进行了详细阐述,建立基于尺寸参数的解析模型;基于体积、铜耗不变的原则,利用所推导的解析模型对其尺寸参数进行了优化,并用有限元法验证了优化结果的准确性;最后比较了新结构与传统结构的主要性能指标。大量结果表明,在相同体积与铜耗的前提下,新结构具有更高的材料利用率和更低的制造、维护成本。
[Abstract]:Because the traditional stator permanent magnet type transverse flux linear oscillation motor adopts permanent magnet attached to stator tooth table, its flux path is in series structure, so it has the disadvantages of large consumption of permanent magnet, high cost of material and difficulty in maintenance, etc. The commercial application of this kind of motor is seriously hindered. A new stator permanent magnet type transverse flux linear oscillating motor is proposed. The permanent magnet attached to the traditional stator tooth surface is embedded in the stator yoke. Firstly, the new topology and its operating principle are described in detail, and an analytical model based on dimension parameters is established, which is based on the principle of volume and constant copper consumption. The dimension parameters are optimized by using the analytical model, and the accuracy of the optimization results is verified by the finite element method. Finally, the main performance indexes of the new structure and the traditional structure are compared. A large number of results show that, With the same volume and copper consumption, the new structure has higher material utilization and lower manufacturing and maintenance costs.
