Product Description Company ProfileLocated in Changsha, Hunan province, Changli Electric Co., Ltd. (formally known as Changsha Motor Factory, which was founded in 1946), is a leading electric motor manufacturer among Top 10 industrial electric motor manufacturers in China. With an investment of 1094 million yuan, the company covers an area of about 400mu (about 270,000m2), has over 600 sets of precision production equipment, with annual production capacity of 8MW. At present, we have over 350 employees, in which engineers and technicians accounting for 18%. With a strong technical research and development team and over 70 years' manufacturing experience, we can produce various kinds of low voltage motors, medium voltage motors and high voltage motors. Our testing center is Hunan Medium and Small Sized Motors Quality Supervision Station, an authorized test station of China National Quality Inspection Center, is responsible for the quality supervision and sampling inspection of motor products of various motor manufacturers in Central and Southern China. We can test 40 series of high and low voltage motors. Our products include standard motors, synchronous/asynchronous motors, high efficiency motors, premium efficiency motors, explosion proof motors, special motors, variable frequency speed regulation motors, ultra-high speed motors, submersible motors, wound rotor slip ring motors, permanent magnet motors, large-sized vertical circulating pump motors, etc. Power range: 0.55KW ~20,000KWVoltage range: 380V to 13.8KVShaft height: 80mm-1120mmProduct DescriptionYB3 Series High Voltage Flameprof Three Phase Induction Motors are the newest products combinind with the design and manufacture experience of long-term and stable producing high-voltage flameproof three-phase inducton motors, adopting the new technique, material and technology, and being of excellent workmanship, these series motors have many remarkable features such as compact construction, lightweight,large power, high efficiency,low noise,small vibration,safe operation and easy maintenance etc.For the enclosure of these series motors,the degree of protecion is lP54 generallly,cooling form is IC411 and mounting arrangement is IMB3. Available are the motors with the diferent protection type,cooling form and mounting arrangement according to customer requirements.This series motors are manufactured with fameproof structures in accordance with the Chinese National Standards GB755 "Rotating electical machines-Rating and Performance", GB3836.1-2010 "Explosive atmospheres, Part 1: Apparatus General requirements" and GB3836.2-2010 "Explosive atmospheres, Part 2: Apparatus protected by the crust for flameproof enclosure "d", The flameproof groups are marked by ExdI Mb, ExdIIA T4 Gb, ExdII B T4 Gb, Exd IIC T4 Gb, suitable for zone 1 and zone 2 hazardous areas where explosive gas and air mixtures exist, this series motors can be used to drive different kinds of general-purpose machines, such as compressors, water pumps, crushers, cutting machine tools, conveying machineries and other mechanical equipment installed in mine, mechanical, petrochemical industries and power plants etc. They can be used as drivers."ExdI Mb" is suitable for the areas where the explosive mixtures containing methane or coal dust exist, but not for the coal mining surface."ExdII A T4 Gb" is suitable for plant areas where the explosive mixtures of Group II A, Temperature Class T1, T2, T3 and T4 exist."ExdII B T4 Gb" is suitable for plant areas where the explosive mixtures of Group II B, Temperature Class T1, T2, T3 and T4 exist."ExdllCT4 Gb" is suitable for plant areas where the explosive mixtures of Group II C, Temperature Class T1, T2, T3 and T4 exist.For the enclosure and the terminal box of this series motors, the protection degree is IP54, IP55 can also be met. The motors can also be manufactured for special environments, such as outdoor locations (YB3-W), indoor tropical humidity (YB3-T), outdoor tropical humidity (YB3-THW), indoor tropical (YB3-TA), outdoor tropical(YB3-TAW), indoor tropical (YB3-T), outdoor tropical (YB3-TW) and outdoor middle-chemical corrosion locations (YB3-WFl), which main installation dimensions are same as the dimension of the basic series motors.Explosion proof products have obtained domestic explosion-proof certification, energy efficiency certification, CCC certification, international IECEx certification, ATEX certification, CUTR certification, etc., and have strong domestic and international competitiveness.Product Parameters Explosion proof certification: Ex d I Mb, Ex d IIB T4 Gb, Ex d IIC T4 Gb Frame Size: H355mm-560mmPower Range: 160KW~2240kWFrequency:50Hz, 60HZProtection Degree: IP44, IP54, IP55,lP56Mounting:IMB3,IMB35,IMB5,IMV1 etc.European explosion proof certification:IEC EX Explosion proof certification; ATEX Explosion proof certificationPoles:2~12PVoltage:3.3KV~13.8KVEfficiency level: IE3 EfficiencyCooling Methods: IC411, IC416 Our AdvantagesSuperior electrical performance: high power density, in line with the concept of green ecology;Low starting current and small impact on power grid;Advanced epoxy anhydride insulation system;The stator adopts vacuum pressure impregnation technology.High reliability: low motor temperature rise;High frame strength;Large space junction box;Small vibration of the whole machine;Perfect winding and bearing temperature monitoring device;Large space grease filling cavity to prolong the greasing cycle.Wide power range availableExcellent starting performanceAvailable to all industry segments and applications in global supplyHighest reliability to minimize operation cost from downtimeHigh flexibility with customizable designOnline Factory Acceptance Test (FAT).
