IC693MDL645LT

IC693MDL645LT油介質(zhì)具有良好的絕緣特性，可以在電機內(nèi)部流動，與電機繞組、定子等發(fā)熱部件直接進行熱交換，也可以在機殼內(nèi)部的流道中循環(huán)流動。這兩種油冷方式分別是直接油冷和間接油冷。直接油冷又可以分為浸油式和噴油式兩種。浸油式油冷是將電機的定轉(zhuǎn)子都浸沒在冷卻油中，具有良好冷卻效果的同時可以降低電機工作噪聲[42]，但是油的黏度較大，增加了電機轉(zhuǎn)子旋轉(zhuǎn)時的能量損失；噴油式油冷通過將冷卻油噴淋到機殼內(nèi)表面及定子端部實現(xiàn)對電機的高效散熱。直接油冷特別是噴油式油冷的冷卻介質(zhì)與電機內(nèi)部的發(fā)熱部件直接接觸，可顯著降低電機繞組、定子等高發(fā)熱部件的散熱熱阻，具有極高的散熱效率，因此多用于高功率密度電機。油冷系統(tǒng)需要嚴格的過濾系統(tǒng)對油介質(zhì)進行過濾，以避免油中的雜質(zhì)對電機內(nèi)部的絕緣層造成破壞。油冷散熱系統(tǒng)的成本昂貴，因此其應(yīng)用規(guī)模不如水冷散熱系統(tǒng)廣泛。Yaskawa JZNC-XIU01B Servo Amplifier JZNCXIU01B
