           Low Voltage Motors >> YE3 Supper High Efficiency Induction Electric Motor (IE3)
          YE3 Supper High Efficiency Induction Electric Motor (IE3)

          Technical characteristics

          Electrical performance data

          Mechanical dimension data

          Totally enclosed fan-cooled motors are designed according to IEC, GB and other standards.

          The frames are made of cast iron, while terminal boxes can be made of steel plate.

          The efficiency can meet the requirements of GB18613-2013 and IEC60034-30 standards.

          Motors with frame 80-132 that are equipped with gasket sealing on DE are standard, and the standard for frame 160 and above motors are with sealing on DE.

          Winding designs can support several kinds of voltage and frequency (50HZ or 60HZ).

          It can stand 1.5 times more of rated current within 2 minutes (IEC60034-1).

          Heater can be added to prevent moisture.

          PTC, PT100 and other thermal elements can be chose to protect winding and bearings.

          Product advantages

          Efficiency improvement

          New winding designs and low loss silicon steel sheets are applied to decrease the motors loss and improve the efficiency.

          Reliable quality and superior characteristics

          In order to insure the good insulation and extend the lifetime, standard motors are examined with F insulation and 80K temperature-rise.

          Voltage, Efficiency

          According to Class A voltage and frequency tolerance demands in IEC60034-1 standard, the motor’s voltage tolerance is ±5%, and the frequency tolerance is ±2%.

          Rated output

          Rated output means it can meet IEC 600341-1 standard, continuous working can output when coolant temperature (CT) is 40℃ and the altitude of working site is under 1000m. Besides, the motors can stand 1.5 times more of rated current within 2 minutes under rated voltage and frequency.


          Motors can be applied to all kinds of machines, such as machine tool, air compressor, pump, ventilation, reduction gear, transmission belt, mining equipment, metallic equipment. However, motors can’t be used with inflammable, explosive and corrosive working site.
