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 GB18613-2012 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.
New winding designs and low loss silicon steel sheets are applied to decrease the motors loss and improve the efficiency.
In order to insure the good insulation and extend the lifetime, standard motors are according to F/B.
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%
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 according to F/B.
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 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.
