的結(jié)構(gòu)，磁鋼固定用保持架的相對(duì)少一些，更多的是用膠水后表貼，然后再纏繞無(wú)緯帶，或者用鋁套或者不銹鋼套固定住。如下附圖二，供參考。5、SPM 的結(jié)構(gòu)，所用的膠水材料資料，如下附圖三，供參考。6、磁鋼為什么要固定，有一個(gè)微信文章，大家可以去查“怎么讓你的磁鋼更安全--永磁電機(jī)的磁鋼固定”，這里面有一些分析，可借鑒參考；大概總結(jié)一下，就是防止磁鋼飛出，防止磁鋼的震動(dòng)等造成壽命降低，加上導(dǎo)熱等功能。四川電鍍磁鋼報(bào)價(jià)一般都是用空載轉(zhuǎn)速的高低和較大扭矩的大小判斷磁鋼的剩磁標(biāo)準(zhǔn)。</p><div
