Y系列电动机是封闭自扇冷式鼠笼型三相异步电动机。是我国统一设计的新的基本系列，它是中国八十年代取代JO2系列的更新换代产品。安装尺寸和功率等级符合IEC标准，外壳防护等级为IP44。
Y系列电动机具有高效、节能、起动转矩高，噪声低，运行安全可靠等优点。 Y系列电动机适用于驱动无特殊要求的各种机械设备，如机床、风机、泵等。 本系统电动机额定电压为380V，频率为50Hz。3kW（4HP）及以下者为Y接法，4kW（5.5HP)及以上者为△接法。电压为220-600V之间，频率为60Hz或湿热带型的电动机，可特殊订货供应。
Y series motors are TEFC (total enclosed fan-cooled) squirrel cage three-Phase asynchronous motors. The whole series is a new basic series designed unitedly in China,so it takes the place of old JO2-series.Mounting dimensions and output ratings are conform-ed with IEC specifications.The degree of protection in Y series is in accord with IP44.
Y series notors have such superior properties as hight efficiency,lower energy consumption,high starting torque,low noise, little vibration and safe running.
Yseries notors are suitable for driving machines and equipments without special raquirements,such as machine tools,blowers and pumps etc.Rated voltage:380V. Rated frequency:50Hz. Y-connection is used for motors of 3 kW(4HP) and below,and△-connection for motors of 4 kW(5.5HP)and over.
Motors with voltages etween 200 to 600V and with freqency of 60Hz or for humid-tropic service type can be ordered specially.
