浙江永磁無刷直流電機

采用(yong)永(yong)磁體勵磁，減少(shao)了勵磁繞(rao)組(zu)(zu)、電(dian)刷(shua)、集電(dian)環結構，避免了傳統(tong)勵磁式發(fa)電(dian)機勵磁繞(rao)組(zu)(zu)易燒毀、斷(duan)線，電(dian)刷(shua)、集電(dian)環易磨(mo)損(sun)等故障，使用(yong)性能更可靠。

轉(zhuan)子不(bu)存在勵磁(ci)繞組、電刷、集電環等損(sun)耗部件，效率得到明顯提高，功率因數可(ke)維持(chi)在0.95以上(shang)，在負載(zai)(zai)波(bo)動的情況下可(ke)維持(chi)較高力(li)能水(shui)平(ping)，對于(yu)該裝(zhuang)備容量與負載(zai)(zai)匹配情況，綜合節電率可(ke)達15%以上(shang)。

1、改變了機械裝備的傳動模式，將永磁電機與機械負載融為一體，簡化機械裝備的傳動鏈，減掉傳統低速機械運行所需的龐大復雜的齒輪減速機，可減少許多制造成本與人力成本。
2、提供機械裝備傳動效率，永磁電機與異步電動機相比，本身效率與功率因數等力能指標有明顯的優越性，再加上取消了機械裝備的中間環節，大幅度的提供了傳動鏈的效率。
3、采用變頻起動，系統帶載起動能力強，切降低了大的起動點了給電網帶來的沖擊，同時也降低了傳動系統的機械沖擊。轉子結構緊湊靈活，可提高電機的轉子表面磁場強度，進而提高轉矩密度，縮小體積和重量。
