臺灣博碩士論文加值系統

現在產業對於線性平台的需求量非常大，同時對系統的響應速度與定位精度的要求也不斷的提升。無鐵心式線性馬達具有直驅的特性，因此響應速度快；且因不具有齒槽結構，所以其速度漣波小、定位精度高。但因產業技術不斷的提升，除了對平台系統的要求愈來越嚴苛，還要顧及設備的使用率及成本。因此提升馬達的推力密度，已是馬達設計的重點課題。
本論文提出在安全操作溫度下，設計一具強制空氣冷卻之無鐵心式線性馬達；並考慮提升線圈繞線密度與氣冷系統散熱效率。通過此設計方法，使無鐵心式線性馬達具有高響應、高精度及高推力密度的特性。
在論文中除建立一設計流程，同時運用電磁場分析(Ansys Maxwell)、結構場分析(Ansys Mechanical)、熱流場分析(Fluent)等軟體，設計一具強制空氣冷卻之無鐵心式線性馬達，並完成其雛型製作。最後再以實驗與模擬相互驗證其設計之可行性。

There’s an increasing demand for linear platform in industry, while the system response speed and positioning accuracy requirements are also rising. The ironless linear motor has the characteristics of direct drive, so the response speed is fast. Because it does not have a cogging structure, so it has small speed ripple, and high positioning accuracy. However, due to continuous improvement of industrial technology, in addition to the requirements of the platform system more stringent, but also take into account the equipment usage and cost. So to enhance the motor thrust density is the key issue in motor design.
This paper proposes an ironless linear motor with a forced air cooling at a safe operating temperature, and considers the coil winding density and the cooling efficiency of the air cooling system. Through this design method, the motor has the characteristics of high response, high precision and high thrust density.
In addition to propose a design process in this paper, the electromagnetic field analysis (Ansys Maxwell), structural field analysis (Ansys Mechanical), and heat flow analysis (Fluent) are used to design an ironless linear motor with forced Air-cooling system and complete its prototype. Finally, the feasibility of the design is verified by experiment and simulation.
Keywords: Ironless linear motor, thrust density, cooling system
