YB2 series compact high voltage flameproof three-phase asynchronous motor company in the digestion and absorption of foreign high-voltage motor manufacturing technology based on, combined with our long-term stable production of high voltage flameproof three-phase induction motor design and manufacturing experience to develop the latest products . This series motors adopt new technologies, new materials, new technology, selected materials, sophisticated manufacturing, small size, light weight, high power, high efficiency, low noise, small vibration, safe and reliable operation, maintenance and easy.
Enclosure protection rating of the motor in this series are generally IP54, cooling method is IC411 the installation IMB3, also be made of different types of protection, cooling, installation methods according to user requirements.
This series motors are the GB755 "Rotating electrical machines - Rating and performance to GB3836.1 explosive gas atmospheres - Electrical equipment - Part 1: General requirements for electrical equipment," GB3836.2 "explosive gas atmospheres Part 2: Flameproof" d " "made of flameproof motor proof mark ExdI, Exd II AT4
Exd II BT4, Exd II CT4, apply to explosive gas atmospheres of Zone 1 and Zone 2 dangerous places. Can be widely used to drive a variety of general machinery: such as compressors, pumps, crushers, cutting machine tools, transportation machinery and other machinery and equipment, mining, machinery industry, petrochemical industry, power plants and other industrial and mining enterprises as the prime mover.
Exd I apply to coal mine methane or coal dust, non-mining face for explosive gas atmospheres.
Exd II AT4 factory Class A, Class II temperature group T1, T2, T3 and T4 group explosive gas environment.
Exd II BT4 apply to the factory Class II Class B temperature groups T1, T2, T3 and T4 group explosive gas environment.
Exd II CT4 applicable to Class II Grade C, the temperature groups T1, T2, T3 and T4 group explosive gas environment in the factory.
The motor of the main shell and the junction box protection class is IP54, can also be made to IP55. YB2-W outdoor type motor can also be made of YB2-TH indoor hot and humid with the type of YB2-THW-outdoor hot and humid with a type of YB2-TA indoor dry tropical type of YB2-TAW outdoor dry tropical type, YB2-T indoor climate and environment of the tropical type, YB2-TW outdoor tropical and outdoor anti-YB2-WF1 moderately corrosive type motors. The main mounting dimensions the same as the basic series motors.
Second, the Structure
This series motors are compact structure of the international fashion, frame, end caps and external surfaces of the distribution of cooling ribs, small size, beautiful appearance.
Stator exterior pressure structure, insulation class F stator coil made with insulated copper flat wound coil by wrapping the main insulation and VPI overall Impregnation with high electric strength, mechanical strength and insulation properties. moisture resistance and thermal stability.
Squirrel-cage rotor, high-precision calibration balancing the motor running smoothly, and little vibration.
High-voltage junction box sealing structure, the wiring cavity, leaving the cable connector position. The location of the junction box is generally the right side of the motor.
According to the different power and speed bearing structure selection: H355 ~~ 560-4,6,8 P Rolling H500, ~ 560-2P with sliding bearings. Rolling bearings of the motor bearings at both ends Note oil discharge device set without stopping the machine, and regular replenishment of grease, sliding bearing end cap-type spherical plain bearings, pressure lubrication, oil ring self-lubricating composite lubrication methods (by the user freedom of choice , as no special requirements, compared with pressure lubrication), while taking measures to prevent the shaft current.
According to user needs, the motor can be installed on the bearing temperature measurement devices or instrumentation to monitor the bearing temperature stator temperature measurement devices, instruments and anti-condensation heating device can also be set according to user needs. Explosion-proof structure of the motor is explosion-proof type of cylindrical, planar and axial curved road.
