目前，無刷電機(jī)的工作原理在當(dāng)代的應(yīng)用可謂是越來越廣泛，無刷電機(jī)的工作原理是值得我們好好學(xué)習(xí)的，現(xiàn)在我們就深入了解無刷電機(jī)的工作原理。 模型無刷電機(jī)的參數(shù)指標(biāo)，除了外形尺寸〔外徑、長度、軸徑等〕重量、電壓范圍、空載電流、電流等參數(shù)外，還少不了一個重要指標(biāo)--KV值，這個數(shù)值是無刷電機(jī)獨有的一個性能參數(shù)，是判斷無刷電機(jī)性能特點的一個重要數(shù)據(jù)。

無刷直流電動機(jī)是采用半導(dǎo)體開關(guān)器件來實現(xiàn)電子換向的，即用電子開關(guān)器件代替?zhèn)鹘y(tǒng)的接觸式換向器和電刷。它具有可靠性高、無換向火花、機(jī)械噪聲低等優(yōu)點，廣泛應(yīng)用于錄音座、錄像機(jī)、電子儀器及自動化辦公設(shè)備中。

LED封裝熱阻主要包括材料內(nèi)部熱阻和界面熱阻。散熱基極的作用主要是吸收芯片產(chǎn)生的熱量，并傳導(dǎo)到熱阻上，實現(xiàn)與外界的熱交換;而減少界面和界面接觸熱阻，增強(qiáng)散熱也是關(guān)鍵。因此芯片和散熱基極的熱界面材料選擇十分重要，目前采用低溫或共晶焊膏或銀膠。德國量一照明使用的LED芯片內(nèi)使用的導(dǎo)熱膠是內(nèi)摻納米顆粒的導(dǎo)熱膠，有效提高了界面?zhèn)鳠?，減少了界面熱阻，加速了LED芯片的散熱。在LED使用過程中，輻射復(fù)合產(chǎn)生的光子在向外發(fā)射時產(chǎn)生的損失，主要有三個方面：芯片內(nèi)部結(jié)構(gòu)缺陷以及材料的吸收，光子在出射界面由于折射率差引起的反射損失；由于入射角大于全反射臨界角而引出的全反射損失；通過在芯片表面覆蓋一層折射率相對較高的透明膠層有效減少光子在界面的損失，提高了取光率。
