摘要

The unmanned aircraft industry is developing safer, lower noise and more efficient power technologies to sustain the transportation industry. Electric motors have many advantages over internal combustion engines. For example, low noise, high torque, high energy efficiency and low maintenance costs. Therefore, hybrid power or electric drones are gradually becoming popular. In this paper, a steady aerodynamic load DC motor model is built in MATLAB. In order to verify the model, several electric motor propeller propulsion set of UAVs have been simulated. It is applied to several simulations. The results of the simulation show the response of power consumption and thrust output to the voltage step input. Comparison of the specific power parameters with the experimental data has been made for model verification. The verification results are quite satisfactory and show the usefulness of this model.

無人飛機正朝向更安全，安靜，高效率方向開發新技術，以維持航空產業的永續發展。電動馬達比內燃式發動機具有更多優點。例如低噪音，高扭力，高能源效率和低廉的維修成本。在可見的未來，混合動力或電動式無人機將逐漸變得更流行。本文提出穩態螺旋槳氣動負載直流馬達的數學模型並用電腦程式進行性能模擬。為了驗證此模型，對於不同組合的馬達和螺旋槳推進機組進行性能模擬。並將比功率參數與實驗數據進行對照比較，驗證結果令人滿意而且顯示出此模型的實用性。
