Different poles offer relative speed. YBD2 series motor are suitable for mechanical equipments which required speed regulation, mainly used in coal,oil and natural gas,petrochemical and chemical industries,usually used to drive pumps,fans,compressors and other transmission machinery. YBD2 series motor could marked as Exd I,Exd II AT4 or Exd II BT4. Exd I is applied in the nonexcavation working condition and coal mine with methane or coal dust,Exd II AT4 and Exd II BT4 are applied in the condition of explosionproof gas compound with Factory II type,Grade A&B, temperature T1,T2,T3 and T4.DescriptionsYBD2 YB2 series three phase AC coal mine explosion proof electric motorIEC80-355 ATEX certificateExd1 and Exd11BT4rated voltage: 380, 400v 415v 440v 460v 660V 50hz 60hz0.75-315KWExplosion Proof Motor, Induction Motor, Electric Motor, YBD2,YB2 Motor YBVP2,YBF2 Motor.YB2 explosion proof motors are designed and manufactured into explosion proof type and the explosion proof property conforms to China National Standards:GB3836.1-2000 Electrical Apparatus for Explosive Gas Atmospheres-General Requirements.GB3836.2-2000 Electrical Apparatus for Explosive Gas Atmospheres- Explosion proof Enclosure d and standards IEC79-1, BS4683 and EN50018.ExdI- safe for use in the non-mining surfaces of underground coal mines where the explosive mixtures of methane or coal-dust are present.ExdIIAT4 - safe for use in plants where the explosive mixtures of IIA Class, TI, T2, T3 or T4 are present.ExdIIBT4 - safe for use in plants where the explosive mixtures of IIB Class, TI, T2, T3 or T4 are present.ExdIICT4 - safe for use in plants where the explosive mixtures of IIC Class, TI, T2, T3 or T4 are present.1.Ambinent tempertuer should not be more than 402.The elevation should not be exceed 1000 meters.3.The relative humindity should not be more than 90%.4.Rated Frequency:50Hz5.Rated voltage: 380V, 660V, 380V/660V6.Operation mode is S17.Protection degree: IP55, Insulation class: FThere are E x d I and ExdIIBT4 type in YB2 ranges of three-phase asynchronous explosion proof motor according to the requirement of the application. The performance of the safety of the products is confirming to the standard of GB3836.1-2000<<Electric Equipment for Using in the Explosive Gas Environment General Equipment, part1:Currency Need>> and GB3836.2-2000<<Electric Equipment for Using in the Explosive Gas Environment General Equipment, part2:Explosion-safe d>>,This ranges of products are suitable for the non-mining working area in underground mine or where there are the explosive gas mixture in factories.WorkconditionsTemperature and InsulationThe Maters' insulation system are designed by Class F(155ºC), operated with Class B(80K). Which incerase the motor useful life and reliability.Cooling and ventilationThe standard cooling method is totally Enclosed Fan Cooled (TEFC) it accordance with IC411 of IEC60034-6. Standard motors are equipped with radialflow plastic fansProtection classThe standard degrees of protection is IP55. The IP55 enclosure means complete hoseproof and dustproof protection .A higher degrees of protection is availableMotor protectionMotors can be installed with PTC, PT100, such as winding and bearing temperature measurement as well as other kinds of protection on request.Voltage and frequencyStandard voltage and frequency are 380V 50HZ, and can be wound for any single voltage it the range 200-660V at a frequency 50hz. The motors will operate satisfactorily with variations of ±5% from the rated voltage.VibrationYB2 motors are designed to vibration class A, vibration class B is available on request.Terminal box locationTerminal box at the top of motorframeQuality assuranceStringent quality procedures are observed from first design to finished products in accordance with ISO9001 documented quality system.Motor working systemThis YB2series of motors working system for S1 continuous duty.Production processing:Features:High starting torqueLow noise and flameproof motorsPower range:0.75-315kwframe range:80H-355HService factor:1.0Rated Volt:380v,400v,415v,440v,575v,660v,690v.Speed range:2p/3000rpm,4p/1500rpm, 6p/1000rpm,8p/750rpmConstruction and frame housing:TEFC.
