Product Title
CST4 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
Efficiency improvement
New winding designs and low loss silicon steel sheets and sheets and advanced manufacture process are applied to decrease the motorsloss and improve the efficiency.
Reliable qualty and superior characteristics.
In order to insure the good insulation and extend the lifetime,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 15%, and the frequency tolerance is ±2%.

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.
