Low-power low-voltage explosion-proof motor YB2-5002-12 YB2 series flameproof three-phase asynchronous motor is my company in the digestion and absorption of the German company Siemens low-voltage high-power electric motor manufacturing technology, based on the combination of our long-term stable production of high pressure flameproof three design phase asynchronous motor license experience and the development of new products. This series motors adopt new technologies, new materials, new technology, selected materials, fine workmanship, with small size, light weight, high power, high efficiency, low noise, little vibration, reliable operation, easy maintenance features. This series of motor enclosure class is usually IP54, cooling method is IC411, installation of IMB3, can also be made of different types of protection, cooling, installation according to user requirements. This series motors comply GB755-2000 "rotary motor fixed and performance", GB3836.1-2000 "Electrical apparatus for explosive gas atmospheres - Part 1: General requirements", GB3836.2-2000 "Electrical apparatus for explosive gas atmospheres - Part 2 : flameproof "d" "provisions made flameproof motors, explosion-proof mark ExdⅠ, ExdⅡ AT4, ExdⅡ BT4, ExdⅡ CT4, apply to have the protection of the environment of a gas and Zone 2 hazardous locations. Can be widely used to drive a variety of general machinery: such as compressors, pumps, crushers, cutting machine tools, transport machinery remember other machinery and equipment, used as a prime mover in the mining industry mining, machinery industry, petrochemical industry, power plants and the like. ExdⅠ applicable to coal mine methane or coal dust in mining face non-explosive atmosphere. ExdⅡAT4 applicable to factories with Class Ⅱ A grade, temperature class for explosive gas atmospheres T1, T2, T3 and T4 groups. ExdⅡBT4 applicable to factories with Class Ⅱ B grade, temperature class for explosive gas atmospheres T1, T2, T3 and T4 groups. ExdⅡCT4 applicable to factories with Class Ⅱ C-class, temperature class for explosive gas atmospheres T1, T2, T3 and T4 groups. Junction box housing and motor body protection rating of IP54, can also be made IP55. The motor can also be made YB2-W Outdoor, YB2-TH households within the humid tropics type, YB2-THW outdoor humid tropics type, YB2-TA indoor dry tropical type, YB2-TAW outdoor dry tropical type, YB2-T Indoor Tropical, YB2-TW outdoor tropical type and YB2-WF1 outdoor anti-corrosion type moderate climate conditions such as motor. The main installation dimensions and the same basic series motors. Model significance such as YB2 450 2-2W Y: asynchronous motor B: flameproof 2: Improved Design number; 450: shaft center height (450mm) 2: core length code (2 cores) 2: series (Level 2) W : Environmental Code (outdoor) structural features of the series motors adopt international popular compact structure, base, both inside and outside surfaces of the end caps are distributed cooling ribs, compact and beautiful appearance. Using exterior pressure stator structure, insulation class F, stator coil using insulated copper flat wire wound coil made by wrapping the main insulation and VPI overall after impregnation with high electric strength, mechanical strength, insulation properties, moisture resistance and thermal stability. Squirrel cage rotor structure, the high-precision calibration balancing, motor running smoothly, small vibration. High voltage junction box is sealed structure, wiring cavity large, leaving the cable connector location. The general location of the junction box on the right motor. Depending on the power and speed of the bearing structure selection: H355 ~ 560-4,6,8P by rolling; H500 ~ 560-2P ??sliding bearings. Non-stop motor bearings located at both ends of the extraction of oil means of rolling bearings, grease can be replenished regularly; sliding bearing cap formula for spherical plain bearings, using pressure lubrication, oil ring or self-lubricating composite lubrication (freely chosen by the user , compared with no special requirements such as user pressure lubrication), while taking measures to prevent shaft currents. According to user needs, the motor can be installed bearing temperature measurement devices or instruments to detect bearing temperature; also put condensing heating device according to the user needs to set the stator temperature measurement devices, instruments and. Flameproof motor structure using cylindrical, planar and curved roads and other proof axial type. Explosion-proof motor YB2-5002-12
