Y2系列三相异步电动机
Y2 SERIES THREE PHASE ELLECTRIC MOTOR
概述:
Y2系列电动机（中心高H63-355mm,0.12-315kw)是全封闭，自扇冷式鼠笼型转子三相异步电动机。该产品达到国际90年代先进水平。它是Y系列的更新换代产品。
Y2系列电动机除了具备Y系列的优点外，与Y系列电机相比，提高了防护等级（IP55），提高了绝缘等级（F级），温升B级考核（除Y2-315L2-2、4极和Y2-355所有规格F级考核外），降低了噪音，且用负载噪声考核，其电机结构更加合理，外形新颖美观。电机冷却方式为IC411，安装尺寸及功率等级符合IEC标准和DIN42673标准。
Y2系列电动机为一般用途的电动机，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，3KW及以下为Y接法，4KW及以上为△接法。
Y2系列电动机一般只有一个轴伸，如用户需要双轴伸，亦可按特殊订货供应。还可按用户要求，设计提供特殊电压、频率、户外型和温热型等其它特殊用途的电动机。
THE SERIES Y2 MOTORS (CENTER HEIGHT H63-355mm,0.12-315kw) ARE TOTALY ENCLOSED FAN COOLED .THREE-PHASE,REFRESHED GENERATION PRODUCT AIMED TO REPLACE THE SERIES IS AN ENTIRELY REFRESHED GENERATION PRODUCT AIMED TO REPLACE THE SERIES Y. IT IS UP TO THE INTERNATIONAL STANDARD IN THE NINETIES.
BESIDES THOSE OF SERIES Y. THE SERIES Y2 MOTORS ARE CHARACTERIZED BY SUCH ON OUTSTANDING FEATURES AS : PROTECTION DEGREE :IP55; INSULATION CLASS:F,TEST:CLASS B(EXECPT Y2-315L2-2#4POLES AND Y2-355 ACCORDING TO CLASS F);LOW NOISE(TEST AT LOAD ); BETTER STRUCTURE .COOLING METHOS IS IC411,THE RATED OUTPUT AND THE MOUNTING DIMENSIONS ARE CONFORMED TO THE STANDARD IEC AND DIN 42673. |
