開關(guān)磁阻電機的前景中外文翻譯-全文預(yù)覽
【正文】 年已運行 500km。對 SR 電機、控制器、功率變換器等的運行理論、優(yōu)化設(shè)計、結(jié)構(gòu)形式等方面進行了更加深入的研究。對開關(guān)磁阻電機的理論研究和實踐證明，該系統(tǒng)具有許多顯著的優(yōu)點： （ 1）電機結(jié)構(gòu)簡單、堅固，制造工藝簡單，成本低，可工作于極 高轉(zhuǎn)速；定子線圈嵌放容易，端部短而牢固，工作可靠，能適用于各種惡劣、高溫甚至強振動環(huán)境。 （ 5）起動轉(zhuǎn)矩大，低速性能好，無感應(yīng)電動機在起動時所出現(xiàn)的沖擊電流現(xiàn)象。開關(guān)磁阻電機的容錯體現(xiàn)在電機某一相損壞，電機照樣可以運行。感應(yīng) 電動機要取得與直流電機相近的調(diào)速特性需采用復(fù)雜的矢量控制系統(tǒng)，而開關(guān)磁阻電機通過調(diào)整開通角、關(guān)斷角、電壓和電流，可以得到不同負(fù)載要求的機械特性，控制簡單、靈活，能容易地實現(xiàn)軟啟動和四象限運行，而且由于這是一種純邏輯的控制方式，很容易智能化，通過修改軟件調(diào)整電機工作特性滿足不同應(yīng)用要求。隨著設(shè)計和制造水平的提高，噪聲必將進一步降低。 free permanent mag rotor can be allowed to have a higher temperature rise. (3) the direction of torque has nothing to do with the current direction, which can be simplified to maximize power converter, reducing system cost. (4) power converter does not arise through failure, and high reliability. (5) starting torque, and lowspeed performance, noninduction motor in the startup arising from the impact of current phenomena. (6) wide range speed control, control flexibility, easy to implement the special requirements of a variety of torque speed characteristics. (7)In a broad range of speed and power efficiency are (8)To fourquadrant operation, has a strong capacity of regenerative braking. (9) Faulttolerant capability. Faulttolerant switched reluctance motor in the motor with a damaged motor can run the same. With the current extensive use of variable frequency induction motor speed pared to switched reluctance motor in terms of cost, efficiency, speed performance, power per unit volume, reliability, heat dissipation and so has the obvious advantage or petitive edge. If the first generation of switched reluctance motor (developed in 1983) in the scope of the efficiency of lowpower efficient than the lowfrequency induction motor speed control, secondgeneration switched reluctance motor (developed
