新型定子永磁型动铁心式横向磁通直线振荡电机
Novel Stator-magnet Moving-iron Transversal-flux Linear Oscillatory Machine
摘要
Abstract
Conventional stator-magnet moving-iron transversal-flux linear oscillatory machine (SMTLOM), suffers from large permanent magnets (PMs) consumption, high material cost and difficulty of maintenance, etc., for its PMs are mounted on stator teeth surface and magnetic circuits constructed in series. Such defects have hindered it from potential applications in the fields that require low cost but high performance. In this paper, one novel stator-magnet moving-iron transversal-flux linear oscillatory machine has been proposed, with PMs inserted in stator yoke, rather than mounted on stator teeth surface. Firstly, the topologies of these two LOMs are described in details, as well as their operation principles. Afterwards, the analytical model of novel SMTLOM is built by using its size parameters. Based on the premises, i.e. same stator outer diameter and copper loss, the optimization of its size parameters is implemented by utilizing such analytical model, of which results are verified by three dimensional finite element method (3D FEM). Finally, their key performance indexes are comprehensively compared. Sufficient simulations validate that under the constraints of same volume and copper loss, the proposed novel SMTLOM has the merits over the conventional one of higher PM utilization ratio and lower cost and difficulty of fabrication and maintenance.关键词
