Y系列電動機是封閉自扇冷式鼠籠型三相異步電動機。是我國統一設計的新的基本系列，它是中國八十年代取代JO2系列的更新換代產品。安裝尺寸和功率等級符合IEC標準，外殼防護等級為IP44。
Y系列電動機具有高效、節能、起動轉矩高，噪聲低，運行安全可靠等優點。 Y系列電動機適用于驅動無特殊要求的各種機械設備，如機床、風機、泵等。 本系統電動機額定電壓為380V，頻率為50Hz。3kW（4HP）及以下者為Y接法，4kW（5.5HP)及以上者為△接法。電壓為220-600V之間，頻率為60Hz或濕熱帶型的電動機，可特殊訂貨供應。
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.
