Y2系列三相异步电动机产品特点及结构简介.doc

Y2系列三相异步电动机产品特点及结构简介（H63355mm）Y2系列三相异步电动机是在Y系列电动机基础上更新设计的一般用途的低压三相笼型异步电动机基本系列。新的基本系列分两种设计（分为两个独立的部分）。第一种设计，即Y2系列（IP54）三相异步电动机，是国内是最为完整的低压笼型三相异步电动机系列。该系列可以满足国内外一般用途的需要，机座范围为63355mm，功率范围为0.12315kW。第二种设计，即Y2-E系列（IP54）三相异步电动机，是为适用于长期连续运行，负载率较高的使用场合，如风机、水泵类的配套需要，电动机具有较高效率和节能效果，机座范围为80280mm，功率范围为0.5590kW。Y2系列（IP54）、Y2-E系列（IP54）以下统称“Y2系列”三相异步电动机。该Y2系列异步电动机具有效率高、起动转矩大等特点。电动机比Y系列提高了外壳防护等级为IP54；提高了绝缘等级为F级绝缘，温升作B级考核，降低了电动机的噪声，用负载噪声考核（原Y系列（IP44）电动机用空载噪声考核）。电动机的结构设计合理，外形美观。Y2系列三相异步电动机的冷却方式为IC411，安装尺寸及功率等级完全符合IEC标准和德国的DIN42673标准，与Y系列（IP44）电动机相同。使用条件 环境空气温度不超过40；海拔不超过1000m；工作方式为连续运行A1工作制；额定电压为380V；额定频率为50Hz；3kW以下为联结，4kW及以上为联结。型号含义Y2系列三相异步电动机的机座号、功率及转速对应关系机 座 号同步转速/（r/min）300015001000750600额定功率/kW 163 20.180.120.250.18 171 20.370.250.180.550.370.25
