1. PRODUCT INTRODUCTION OF IE3 ELECTRIC MOTOR
YE3 series are 3 phase asychronous electric motors with totally enclosed fan cooled,are ac motor,industrial motors. The premium efficiency motors are developed by ourselves independently according to standard IEC,GB,etc. The energy-saving motors meet with efficiency IE3 of IEC60034-30 and efficiency Grade 2 of GB18613-2012.The IE3 INDUCTION MOTORs are also in compliance with the efficiency standards covered by NEMA, CSA, CEMEP, COPANT, AS, NZS, JIS, GB. it is the most authoritative efficiency classification standard in the world.
The output rated power and mounting dimensions of the motors are perfectly in accordance with IEC60072-1. YE3 motors is reasonable structure, small vibration and low noise.
YE3 series 3 phase asychronous motors can be widely used in blowers,ventilators,pumps,machine tools, compressor, reducers, packing machines,transportation machinery,mining equipment,construction equipment and other machines,which can operate with full load for a long time,the three phase electric motors can save the considerable electric energy,it is advantageous to protect the environment.
