產(chǎn)品詳情
直流電機(jī)的原理 直流電機(jī)原則上既可以作為電動(dòng)機(jī)運(yùn)行,也可以作為發(fā)電機(jī)運(yùn)行,這種原理在電機(jī)理論中稱(chēng)為可逆原理。作為發(fā)電機(jī)運(yùn)行時(shí),當(dāng)原動(dòng)機(jī)驅(qū)動(dòng)電樞繞組在主磁極N、S之間旋轉(zhuǎn)時(shí),電樞繞組上感生出電動(dòng)勢(shì),經(jīng)電刷、換向器裝置整流為直流后,引向外部負(fù)載(或電網(wǎng)),對(duì)外供電。而如果用外部直流電源,經(jīng)電刷換向器裝置將直流電流引向電樞繞組,則此電流與主磁極N.S.產(chǎn)生的磁場(chǎng)互相作用,產(chǎn)生轉(zhuǎn)矩,驅(qū)動(dòng)轉(zhuǎn)子與連接于其上的機(jī)械負(fù)載工作,此時(shí)電機(jī)作直流電動(dòng)機(jī)運(yùn)行。直流電機(jī)的額定值

PU聚氨脂橡膠密封圈:PU聚氨脂橡膠密封圈的機(jī)械性能非常好,耐磨、耐高壓性能均遠(yuǎn)優(yōu)于其它橡膠;PU聚氨脂橡膠密封圈的耐老化性、耐臭氧性、耐油性也相當(dāng)好,但高溫易水解;PU聚氨脂橡膠密封圈一般用于耐高壓、耐磨損密封環(huán)節(jié),如液壓缸,PU聚氨脂橡膠密封圈一般使用溫度范圍為-45~9℃。HNBR氫化丁氰橡膠密封圈:HNBR氫化丁氰橡膠密封圈具有的抗腐蝕、抗撕裂和抗壓縮變形特性,耐臭氧、耐陽(yáng)光、耐天候性較好,比丁氰橡膠有更佳的抗磨性;HNBR氫化丁氰橡膠密封圈適用于洗滌機(jī)械、汽車(chē)發(fā)動(dòng)機(jī)系統(tǒng)及使用環(huán)保冷媒R134a的制冷系統(tǒng)中;不建議HNBR氫化丁氰橡膠密封圈使用于醇類(lèi)、酯類(lèi)或是芳香族的溶液中,一般HNBR氫化丁氰橡膠密封圈的使用溫度范圍為-4~15℃。

電動(dòng)自行車(chē)的發(fā)展離不開(kāi)其所采用的核心驅(qū)動(dòng)元件——電機(jī)的發(fā)展,其實(shí)電機(jī)本身的發(fā)展自有其規(guī)律,但把電機(jī)與自行車(chē)結(jié)合起來(lái)研究將是一件十分有意義的事情。本文簡(jiǎn)述目前國(guó)內(nèi)市場(chǎng)上電動(dòng)自行車(chē)中所采用的各種直流電機(jī)的基本概況,指出其產(chǎn)品類(lèi)型、結(jié)構(gòu)、性能特點(diǎn)、使用場(chǎng)合等。
2 分 類(lèi)
2.1 按電機(jī)類(lèi)型分類(lèi)
電動(dòng)自行車(chē)所用直流電機(jī)按電機(jī)本身類(lèi)型可分成以下幾類(lèi)。
2.1.1 普通永磁直流電動(dòng)機(jī)
這類(lèi)電機(jī)即為通常使用的永磁直流電動(dòng)機(jī)。電機(jī)定子為鐵氧體或釹鐵硼永磁磁鋼磁極,轉(zhuǎn)子為普通直流電機(jī)轉(zhuǎn)子,電機(jī)轉(zhuǎn)速2000~4000r/min。這類(lèi)電機(jī)需配備減速齒輪箱后才能用于電動(dòng)自行車(chē)上。
