永磁無刷馬達頓轉轉矩的產生是由於轉子磁石與定子槽齒間的交互作用。因為頓轉轉矩會促使馬達產生漣波輸出、震動與噪音,所以在馬達使用上,頓轉轉矩是不受歡迎的。
本論文旨在探討如何降低永磁無刷馬達的頓轉轉矩。有許多方法可以用來降低馬達的頓轉轉矩,例如:修改磁石弧長、改變磁石充磁方式、定子齒部設置輔助槽、修改靴部深度、槽與極不同組合。文中將利用有限元素法分析軟體Flux2D為分析工具,分別探討各種降低馬達頓轉轉矩的方法,並比較其結果。
Cogging torque results from the interaction between the permanent magnets mounted on the rotor and the stator anisotropic, due to the slotting , It is undesirable and may cause speed ripple and vibration.
The purpose of this thesis is to study the methods for reducing the cogging torque in permanent magnet brushless motors, presented in the literatures. Examples such as, varying the magnet arc, varying the magnetization of magnets, notches in the stator teeth, varying the radial shoe depth, pole and slot combination.
Results and comparison are conducted using the finite element analysis software Flux2D.
