Product Title
CST3 Series High Efficiency Motors
Production Details
Technlcal charactorlstlcs
Totally enclosed fan-cooled motors are designed according to IEC,GB and other standards.
The frames are made of cast iron.
The efficiency value meets the requirements of GB18613-2020 and IEC60034-30 standards.
Winding designs can support several kinds of voltage and frequency(50HZ or 60HZ).
Withstand 1.5 times of rated current for 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.
Produet advantages
Efficlency Improvement
Now winding deslgns and low loss sillcon steel sheete and
advanced manufacture process are applied to decrease the
motors loss and improve the efficiency.
Reliable quality and superior characteristics
ln order to Insure the good Insulatlon and extend the
llfetime,standard motors are accordIng to F/B.
Rated output
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 meansitcanmeetlEC600341standard,continuous working can output when coolanttemperature(CT)iS 40'C and the altltude of working slte lsunder 1000m.Besides,the motors can stand 1.5 times more ofrated current within 2 minutes under rated voltage andfrequency.

Common Materials Of Motor
Copper
Copper can be drawn into flat shapes to form rectangular winding wires. Rectangular winding wires are integral components in compact and high-performance applications like electric vehicle motors, EV power trains etc.
Steel
Silicon steel offers good shielding properties against electromagnetic interference. Therefore, it is useful in equipment where the radiation needs minimizing, such as medical instrumentation or transport systems like railroads.
Cast Iron
Cast iron is a good choice for an engine block. It is easily sand cast, easy to machine, capable to resist piston wear quite well, and inexpensive as a material.
Silicon steel sheet
The silicon steels are produced in two forms, highly textured grain-oriented alloys and alloys in which the grains are not oriented. Grain orientation is carried out to align the magnetic easy axis.
