Y2系列(IP54)三相异步电动机      Y2系列（中心高H63-H355、0.18-315kW）电动机是全封闭、自扇冷式笼型三相异步电动机，是取代Y系列（IP44）电动机的更新换代产品，产品达到90年代国际先进水平。    Y2系列电动机较Y系列电动机的效率高、起动转矩大、提高了防护等级（IP54）、提高了绝缘等级（F级、按B级考核）、降低了噪声（用负载噪声考核），电动机外型新颖美观，结构更加合理。其功率等级及安装尺寸与Y系列电动机相同，完全符合IEC标准。    Y2系列电动机是一般用途的电动机，适用于驱动无特殊要求的各种机械设备。    Y2系列电动机额定电压为380V、额定频率为50Hz、防护等级为IP54、冷却方式为IC0141，3kW以下为Y接，4kW以上为△接，环境温度不超过40℃。最低温度为-15℃，海拔不超过1000m，工作方式为连续（S1）。安装模式H63-H355 IMB3、B35、V1；H63-H280 IMB5；H63-H112 IMB14、B34、V15、V18；H63-H160 IMB6、B7、B8、V3、V5、V6、V36。Y2安装尺寸及外形尺寸 B5机座号凸缘号极数安装尺寸(mm)外形尺寸(mm)DEFGMNPRSTACHFLY2YPF80FF1652.4.6.81940615.516513020004-Φ123.517523529534590S2.4.6.8245082016513020004-Φ123.519525031538590L2.4.6.8245082016513020004-Φ123.5195270340410100LFF2152.4.6.8286082421518025004-Φ14.54215280385450112M2.4.6.8286082421518025004-Φ14.54240360400445132SFF2652.4.6.83880103326523030004-Φ14.54275360470520132M2.4.6.83880103326523030004-Φ14.54275360510560160MFF3002.4.6.842110123730025035004-Φ18.55330430615660160L2.4.6.842110123730025035004-Φ18.55330430670715180M2.4.6.8481101442.530025035004-Φ18.55380500700720180L2.4.6.8481101442.530025035004-Φ18.55380500740760200LFF3502.4.6.855110164935030040004-Φ18.55420550770840225SFF4004.860140185340035045008-Φ18.55470610815895225M255110164940035045008-Φ18.55470610820—4.6.860140185340035045008-Φ18.55470610845925250MFF500260140185350045055008-Φ18.55510650910—4.6.865140185850045055008-Φ18.55510650910990280S265140185850045055008-Φ18.55580720985—4.6.8751402067.550045055008-Φ18.555807209851110280M265140185850045055008-Φ18.555807201035—4.6.8751402067.550045055008-Φ18.5558072010351160315SFF600265140185860055066008-Φ2466459001160—4.6.8.1080170227160055066008-Φ24664590012701330315M265140185860055066008-Φ2466459001190—4.6.8.1080170227160055066008-Φ24664590013001390315L265140185860055066008-Φ2466459001190—4.6.8.1080170227160055066008-Φ24664590013001390355M2751402067.574068080008-Φ24671010101500—4.6.8.1095170258674068080008-Φ246710101015301630355L2751402067.574068080008-Φ24671010101500—4.6.8.1095170258674068080008-Φ246710101015301630
