style="text-indent:25px">我們都知道釤鈷磁鐵和釹鐵硼磁鐵的使用很普遍，它們有些性能差不多，但也有些性能相差很大。現(xiàn)在我們就來看看釤鈷磁鐵制成的電機(jī)和釹鐵硼磁鐵制成的電機(jī)有什么不同。釤鈷磁鐵由于磁能密度較釹鐵硼磁鐵的密度低，因而所建立的能量轉(zhuǎn)換所必需的氣隙磁場(chǎng)強(qiáng)度沒有釹鐵硼磁鐵高，所以制造永磁電機(jī)的容量要小一些。釹鐵硼永磁問世后，情況發(fā)生了重大變化。高性能釹鐵硼磁體產(chǎn)生的磁場(chǎng)，不僅可以達(dá)到電流勵(lì)磁所產(chǎn)生的磁場(chǎng)強(qiáng)度，而且還遠(yuǎn)遠(yuǎn)超過電流勵(lì)磁，因而可以制造出數(shù)千kW的大中型電機(jī)。</p><p
