style="text-indent:25px">從直流電動機到交流電動機，人們從來沒有停止為研制高性能電機而努力奮斗?！按磐酢扁S鐵硼永磁體的出現(xiàn)，徹底改變了電機行業(yè)，人們開始生產(chǎn)稀土永磁電機，利用稀土永磁材料產(chǎn)生磁場，替代傳統(tǒng)電機由電流勵磁產(chǎn)生的磁場，使得稀土永磁電機具有結構簡單、運行可靠、體積小、重量輕、損耗低、效率高，電動機的外型和尺寸可以靈活多變等明顯特點，所以稀土永磁電機近幾年來得到迅猛發(fā)展，同時也帶動了相關產(chǎn)業(yè)產(chǎn)品的提高，使機電一體化達到了更新的層次。稀土永磁直流無刷調(diào)速電機是現(xiàn)代材料科學、電子電力科學及電動機控制理論相結合的產(chǎn)物。</p><p style="text-indent:25px">釹鐵硼主要優(yōu)點：性價比高，并且在機械方向上擁有不錯的特性缺點在于：居里溫度點偏低，同時溫度特性較差，并容易發(fā)生粉化腐蝕，必須通過調(diào)整其化學成分和采取表面處理方法（如鍍鋅等）使化學性能上得到改進，才能達到我們需要的實際應用要求。而鐵氧體永久磁鐵是一類擁有鐵磁性的金屬氧化物。就電特性來說，鐵氧體永久磁鐵的電阻率相比于比金屬與合金磁性材料來要大得多，并有稍偏高的介電性能。釹鐵硼永久磁鐵和鐵氧體永久磁鐵磁鐵的區(qū)別主要有以下幾點：1.鐵氧體永久磁鐵性能不如釹鐵硼永久磁鐵。2.價格上.鐵氧體永久磁鐵的要比釹鐵硼永久磁鐵磁鐵便宜很多。3.釹鐵硼永久磁鐵耐溫很好，而普通的釹鐵硼永久磁鐵通常只能80度，超過了這個工作溫度就會出現(xiàn)退磁情況。4.鐵氧體永久磁鐵穩(wěn)定性非常好，它本身是氧化物，很穩(wěn)定，釹鐵硼永久磁鐵是合金，及其容易氧化、必須做涂層保護。已成功地在火箭、導彈上應用了稀土永磁電機。</p><div
