Can't read the hydraulic motor model? In fact, not so complicated, Dalan Motor to teach you!


The motor model is a code number that is used in the convenience of use, design, manufacturing, etc. for business contact and simplification of product names, specifications, types, etc. in technical documents. Below, Dalan Motor Xiaobian introduces the meaning of the hydraulic motor model.

The composition of the motor model: there are four summary sequences of the motor type code, the motor characteristic code, the serial number and the excitation mode code.

The type code is a Chinese phonetic alphabet used to characterize various types of motors.

For example: asynchronous motor Y, DC motor T, synchronous generator TF, DC motor Z DC generator ZF.

The feature code is to characterize the performance, structure or use of the motor, and is also represented by the Chinese phonetic alphabet.

For example: flameproof type with B; YB axis flow fan with YT; electromagnetic brake type YEJ; variable frequency speed control type YD; crane with YZD.

The design serial number refers to the order in which the motor product is designed and is represented by Arabic numerals. For the first design, the design serial number is not marked, and the products derived from the series are marked in the order of design, such as Y2, YB2.

The excitation mode codes are respectively represented by letters, S represents the third harmonic, J represents the thyristor, and X represents the complex excitation.

Such as: Y2-160 M1-8, Y: model, indicating asynchronous motor 2: design serial number, indicating the product based on the first design improvement, 160: center height.

The Y series is a fully enclosed self-fan-cooled three-phase squirrel-cage asynchronous motor. Use is very common.

The YS series three-phase asynchronous motor has low power and is suitable for driving small machine tools, pumps and compressors. The junction box is on the top of the motor.

The YSF and YT series are not much different. They are all three-phase asynchronous motors for fans. According to the matching requirements of the fan industry, the motor has adopted a series of noise reduction and vibration reduction measures. This series of motors has the characteristics of high efficiency, energy saving, low noise, good starting performance, reliable operation and convenient installation. Suitable for fan installation and use, it is an ideal accessory for fans.

YD is a multi-speed three-phase asynchronous motor, generally has 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 pole.

The YL series is a two-value capacitor single-phase asynchronous motor, that is, there are two capacitors.

The YC series is a single-phase capacitor start asynchronous motor.

The YY series is a single-phase capacitor running asynchronous electric.

The SG series is a high-protection three-phase asynchronous motor that can be interchanged with the Y series, but the performance is enhanced (such as the adjustment and optimization of the electromagnetic scheme, some specifications use cold-rolled silicon steel sheets, etc.), so that the vibration and noise of the series of motors (especially load noise) is significantly lower than Y series motors.

The experiment proves that the noise of this series of motors reaches the Class I standard, and the vibration value of the motor is one priority lower than the Y series standard. The shaft end bearing has an oil filling device, and the bearing can be changed without disassembling the motor, and the maintenance is simple.

YCT series electromagnetic speed regulating motor is a kind of speed regulating motor that adjusts the output shaft torque and speed by changing the magnitude of the excitation current. It can be used in the speed adjustment and tension control of constant torque load, and is more suitable for the case of blower and pump load. For the load with high starting torque and large inertia, it has the function of buffer starting, and also has protection against overload.

Through the above detailed description of the motor model, I believe we can see the type of the motor in the future.
