【摘要】：本文針對永磁直流電機的工作原理和設計方法進行了分析和研究，，設計了一臺2極8槽永磁直流電動機。并應用Visual Basic語言，編制了一套電機的電磁場有限元分析程序。采用該有限元分析程序，對設計的永磁直流電機的性能進行了計算與分析，如果性能不合要求，調(diào)整電機的某些尺寸后，反復計算，直到電機的性能和設計經(jīng)濟性達到相對最優(yōu)，從而確定為最終的設計方案。 首先，根據(jù)永磁直流電機的設計原理和設計經(jīng)驗，采用等效磁路法，初步確定了電機的結(jié)構(gòu)尺寸。 然后，建立永磁直流電機的有限元數(shù)學模型，采用Visual Basic語言，編制了電磁場的二維有限元計算程序，并通過微型計算機調(diào)試通過。采用該有限元計算程序，對所設計的初始方案進行了性能核算，根據(jù)設計要求，對個別尺寸進行了調(diào)整。通過反復調(diào)整和核算后，確定了最終的設計方案。 最后，針對最終設計方案，應用有限元計算程序，算出了電機的運行特性，繪制出電機分別在空載和負載時的磁場分布圖和氣隙磁密曲線，負載時的電磁轉(zhuǎn)矩曲線和工作特性曲線等。經(jīng)對比部分計算結(jié)果與實驗室測試數(shù)據(jù)，結(jié)果基本吻合。 此外，本文還介紹了所開發(fā)軟件的特點、功能和使用方法。詳細介紹了軟件的設計步驟、設計流程和運行界面。
[Abstract]:In this paper, the working principle and design method of permanent magnet DC motor are analyzed and studied, and a 2-pole 8-slot permanent magnet DC motor is designed. Using Visual basic language, a finite element analysis program of electromagnetic field of motor is developed. The finite element analysis program is used to calculate and analyze the performance of the designed permanent magnet DC motor. If the performance is not up to requirements, some dimensions of the motor are adjusted and calculated repeatedly. First, according to the design principle and experience of permanent magnet DC motor, the equivalent magnetic circuit method is adopted. Then, the finite element mathematical model of permanent magnet DC motor is established, and the two-dimensional finite element calculation program of electromagnetic field is compiled by Visual basic language, and the program is debugged by microcomputer. Using the finite element calculation program, the performance of the initial scheme is calculated, and the individual dimensions are adjusted according to the design requirements. After repeated adjustment and calculation, the final design scheme is determined. Finally, the running characteristics of the motor are calculated by using finite element calculation program for the final design scheme. The magnetic field distribution diagram and air-gap magnetic density curve, the electromagnetic torque curve and the working characteristic curve of the motor under no load and load, respectively, are plotted. The results are in good agreement with the experimental data. In addition, this paper introduces the features, functions and usage of the software. The design steps, design flow and running interface of the software are introduced in detail.
