To know what type of motor is, where it is used, and the basic parameters of the motor.MotorAn electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Explosion-proof motor is a kind of motor that can be used in flammable and explosive plants, and it does not generate electric sparks during operation.Explosion-proof motorsMainly used in coal mines, petroleum and natural gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.These things are not that difficult, so let's sort them out:
Generally speaking, the motor model has four parts: product code, specification code and supplementary code.
Example 2: YB280 4-2W. Y stands for asynchronous motor, B stands for fire protection, 280 stands for secondary program, frame size is XNUMX (with high performance center), S is short base (M is basic, L is long base), W stands for outdoor activities.
Example 2: YKK4502-4 displays the second power supply in seat number 450.
The meaning of the code in the model:
Y- stands for "different" step motor;
B- stands for "explosion-proof", YB stands for explosion-proof asynchronous AC motor;
A- stands for increased-safety explosion-proof, ya stands for increased-safety asynchronous motor, yb belongs to explosion-proof motor;
K- stands for "air" cold, represents the induction motor of the body YKK, the first cooler, and the secondary cooling medium to cool the atmosphere;
S- stands for "water" cooling and transporting "transportation" machines. For example, YBKS stands for air cooling in a motor enterprise, and the cooler is an explosion-proof design motor of the water cooling treatment system;
Conveyor YBS special explosion-proof motor
R- stands for "wound" rotor system motor, for example, YR is an asynchronous AC motor with wound rotor;
P- means shielding, such as YP is shielded asynchronous motor;
If yl is a vertical asynchronous motor, then l- represents the "vertical" type;
J- represents the "torsion" of the motor vehicle, such as the special explosion-proof motor of the YBJ winch device;
F- stands for "ventilation" and "dust". For example, YBF stands for China's fans for special equipment explosion-proof design motors, and YFB stands for enterprise dust explosion-proof motors;
T- stands for "synchronous" step, and TYBPE stands for synchronously improving the permanent magnet explosion-proof frequency modulation control motor.
W- stands for "no" spark, brushless excitation, such as YW stands for non-sparking three-phase AC asynchronous control motor, TAW stands for increased safety brushless excitation synchronous motor.
GB- stands for "pipe" and "pump", for example, YBGB stands for flameproof asynchronous AC motors for pipelines;
PT- stands for variable frequency speed regulation
It should be pointed out that the Chinese Pinyin letters represent all models, the type of motor installed is very simple to understand and remember, how about the model electrode is it better to understand it?
