我的畢業(yè)設(shè)計(jì)題目是：直流無(wú)刷電機(jī)調(diào)速系統(tǒng)設(shè)計(jì)

【專家解說(shuō)】：永磁無(wú)刷直流電機(jī)調(diào)速系統(tǒng)設(shè)計(jì)The System of Speed Adjustment for Permanent Magnet Brushless DC Motor 無(wú)刷永磁直流電機(jī)隨著電力電子技術(shù)的發(fā)展，許多新型的高性能半導(dǎo)體功率器件，如GRT、MOSFET、IGBT等相繼出現(xiàn)以及高性能永磁材料，如稀土永磁材料的問(wèn)世，為無(wú)刷直流電動(dòng)機(jī)的廣泛應(yīng)用奠定的基礎(chǔ)，無(wú)刷永磁直流電機(jī)正在以其特有的優(yōu)勢(shì)不斷蓬勃發(fā)展。為了能對(duì)無(wú)刷直流電機(jī)有一個(gè)足夠并且更深入的認(rèn)識(shí)，本課題從無(wú)刷永磁直流電機(jī)的結(jié)構(gòu)、原理、控制以及具體的應(yīng)用方面展開(kāi)了討論，特別是在原理方面，從而為后面的控制部分打下基礎(chǔ)，并且依據(jù)自己的思路，試著設(shè)計(jì)一臺(tái)電機(jī)，希望自己能把所學(xué)的知識(shí)應(yīng)用到實(shí)際。最后，通過(guò)對(duì)無(wú)刷永磁直流電機(jī)在輕型汽車上的應(yīng)用結(jié)束設(shè)計(jì)的內(nèi)容。 With the development of Power Electronic Technique and the following appearance of many high capability semiconductor, such as GRT、MOSFET、IGBT. And some high quality permanent magnetic material also gives Direct Current Electromotor a good foundation, such as rare earth. As a result, Direct Current Electromotor is developing vigorously. In order to make Direct Current Electromotor more familiar ,I want to see the structure、principle 、control and the practical use of the Direct Current Electromotor. Especially, I spend a lot ink to study the electromotor’ principle, so I can make the control part more easily. And I also want to design an electromotor in order to throw the knowledge I have learnt into practice. At last, I have a dream that all buses’ motor can be replaced by Direct Current Electromotor, so that we can save more energy and make the world more beautiful.
