The meaning of Y, YS, YSF, YT and other letters in the motor model

The Y series is a fully enclosed self-fan-cooled three-phase squirrel-cage asynchronous motor. Use is very common
YS series three-phase asynchronous motors have low power and are suitable for driving small machine tools, pumps, and compressors. The junction box is on the top of the motor.
YSF, YT series difference is not big, are fan special three-phase asynchronous motor, is according to the fan industry supporting requirements, the motor in the structure to take a series of noise reduction, vibration reduction measures. This series of motors has the characteristics of high efficiency, energy saving, low noise, good starting performance, reliable operation, convenient installation and so on. Suitable for fan installation and use, is the ideal fan supporting products.
YD is a multi-speed three-phase asynchronous motor, generally with 4/2 poles 8/6 poles 8/4/2 poles 6/4 poles 12/6 poles 8/6/4 poles 8/4 poles 6/4/2 poles 12/8/6/4 poles
YL series is a double-value capacitor single-phase asynchronous motor, that is, there are two capacitors
YC series for single-phase capacitor start asynchronous motor
YY series for single-phase capacitor operation asynchronous electric
SG series is a three-phase asynchronous motor with high protection grade, which can be interchanged with Y series, but its performance has been strengthened (such as the adjustment and optimization of electromagnetic scheme, some specifications adopt cold-rolled silicon steel sheet, etc.), so that the vibration and noise (especially load noise) of this series motor are significantly lower than that of Y series motor. Experiments show that the noise of the series motor reaches the I-level standard, and the vibration value of the motor is 1 priority lower than the Y-series standard. The oil injection device is added to the shaft extension end bearing, and the oil change can be carried out on the bearing without disassembling the motor, and the maintenance is simple.
The YCT series is an electromagnetic speed-regulating motor, which is a speed-regulating motor that adjusts the output shaft torque and speed by changing the excitation current. It can be applied to the speed adjustment and tension control of constant torque load, and is more suitable for the occasions of blower and pump load. For the load with high starting torque and large inertia, it has the function of buffering starting, and at the same time has the protection function of preventing overload.
YP2 series is a three-phase asynchronous motor with variable frequency speed regulation, which is a three-phase asynchronous motor with frequency converter as power supply. By changing the power frequency to achieve smooth adjustment of the motor speed, to achieve energy saving and control automation purposes. YP2 series motors have high efficiency, wide speed range, high precision, stable operation, convenient operation and maintenance, and their installation dimensions meet the International Electrotechnical Commission (IEC) standards. They are divided into two types: self-fan cooling and external fan cooling.
CXT series is a rare earth permanent magnet three-phase synchronous motor, which is made of new rare earth permanent magnet materials and other high-quality materials. It has great innovations in rotor structure design and electromagnetic parameter selection, which enables the motor to have ultra-high efficiency and power factor (the power factor reaches more than 95%), thus having high starting performance, high pull-in synchronous torque and large overload capacity, and the motor efficiency curve is relatively straight, low load also has high efficiency, can be widely used in petroleum, chemical, metallurgy, mining, textile and other long-term load operation of the equipment.
YLZC series is a special motor for cooling towers. The protection grade of the motor shell is IP45 (or IP55). The series of motors adopt-series noise reduction, vibration reduction, waterproof and moisture-proof measures in structure, which have some advantages such as low noise, high efficiency, waterproof and moisture-proof.
