2)大慣量寬調(diào)連直流伺服電機(jī)
大慣量寬調(diào)速直流伺服電機(jī)又稱直流力矩電機(jī)。一方面,由于它的轉(zhuǎn)子直徑較大,線圈繞組匝數(shù)增加,力矩大,轉(zhuǎn)動慣量比較其他類型電機(jī)大,且能夠在較大過載轉(zhuǎn)矩時(shí)長時(shí)間地工作,因此可以直接與絲杠相連,不需要中間傳動裝置。另一方面,由于它沒有勵(lì)磁回路的損耗,它的外形尺寸比類似的其他直流伺服電機(jī)小。它還有一個(gè)突出的特點(diǎn),是能夠在較低轉(zhuǎn)速下實(shí)現(xiàn)平穩(wěn)運(yùn)行,轉(zhuǎn)速可以達(dá)到1r/min,甚至0.1r/min。因此,這種伺服電機(jī)在數(shù)控機(jī)床上得到了廣泛地應(yīng)用。
3)無刷直流伺服電機(jī)
無刷直流伺服電機(jī)又叫無整流子電機(jī)。它沒有換向器,由同步電機(jī)和逆變器組成,逆變器由裝在轉(zhuǎn)于上的轉(zhuǎn)于位置傳感器控制。它實(shí)質(zhì)是一種交流調(diào)速電機(jī),由于其調(diào)速性能可達(dá)到直流伺服發(fā)電機(jī)的水平,又取消了換向裝置和電刷部件,大大地提高了電機(jī)的使用壽命。

3.3 中置式電機(jī)
凡將驅(qū)動電機(jī)裝在自行車腳踏處的這種安裝方式,其所采用的電機(jī)統(tǒng)稱為中置式電機(jī)。這類電機(jī)是通過鏈輪鏈條傳遞動力至后輪。3.3.1普通無刷直流電機(jī)
這類電機(jī)即為通常使用的內(nèi)轉(zhuǎn)子式無刷直流電機(jī),電機(jī)結(jié)構(gòu)簡單,已有相當(dāng)成熟的加工手段,電機(jī)成本較低。由于采用無刷控制,因此電機(jī)性能優(yōu)異。
3.3.2 普通永磁直流電機(jī)
這類電機(jī)是普通的永磁直流電機(jī),電機(jī)結(jié)構(gòu)簡單,工作穩(wěn)定,可靠,生產(chǎn)加工成熟。定子可采用早期的鐵氧體永磁材料,也可采用當(dāng)今高性能稀土永磁材料釹鐵硼。采用鐵氧體磁鋼電機(jī)性能要差一些,但電機(jī)成本低一些;而采用釹鐵硼磁鋼電機(jī)性能將十分好,比如轉(zhuǎn)速低、效率較高、換向性能好等。

上例即在測完此圖后兩小時(shí)轉(zhuǎn)子抱軸。在診斷這些假冒偽劣軸承故障時(shí),要注意多積累平時(shí)優(yōu)質(zhì)軸承在設(shè)備上正常運(yùn)行的頻譜和振動時(shí)域情況,便于在出現(xiàn)此類異常頻譜時(shí)能及時(shí)判斷出軸承故障,避免設(shè)備事故。實(shí)用的滾動軸承快速診斷技巧我們在實(shí)際狀態(tài)監(jiān)測中,往往只需判斷滾動軸承好壞,能用多長時(shí)間,而精密分析及診斷中診斷軸承某個(gè)部位故障往往實(shí)用性不大。實(shí)用中精密診斷由于受工況等因素影響,時(shí)常找不出滾動軸承對應(yīng)的特征頻率。雖然近幾年發(fā)展出的小波分析與快速共振動解調(diào)分析技術(shù)比較準(zhǔn)確,但所需設(shè)備投入較大,還需進(jìn)行較多分析,現(xiàn)場故障診斷人員一般較少應(yīng)用。
