YBX3 Series Explosion-Proof Three-Phase Induction Motors

Guangzhou Haoqing Mechanical And Electrical Equipment Co., Ltd. is one of the leading manufacturers and suppliers of ybx3 series explosion-proof three-phase induction motors in China. Welcome to buy high-grade ybx3 series explosion-proof three-phase induction motors made in China here from our factory. All customized products are with high quality and low price.

YBX3 series of flameproof three-phase induction motors type of H63~355 are latest products developed by our company combining with home and abroad electromagnetic structure, technique and material etc based on YB2 and YB3 series of motors. This series of motors have many merits such as high-efficiency, energy conservation, big margin of temperature rise, long service life, excellent performance, low noise, advanced explosion-proof structure, high reliability and convenient operation and maintenance etc. The efficiency index of this series motors confirms to the energy efficiency grades 2 of specified in GB18613-2012 Minimum allowable values of energy efficiency and the energy efficiency grades for small and medium three-phase asynchronous motors. Power class and the installation dimensions accord with IEC standard , also completely in the same way as YB2 and YB3 series three-phase induction motors. This series of motors meet GB755-2008 "Rotating electrical machines-Rating and performance". Their flameproof performance should meet GB3836.1-2010 "Explosive atmospheres, Part1:Apparatus General requirements" and GB3836.2-2010"Explosive atmospheres, Part2: Apparatus protected by the crust for flameproof "d" ". The flameproof types of this series of motors are ExdI, ExdIIAT4 and ExdIIBT4. This series of motors are suitable for the non-mining working area in underground mine or the dangerous locations in factories where there are the explosive gas of class IIA and IIB and temperature of class T1～T4.Shell protection degree of this series of motors is IP55, the cooling system is IC411.This series of motors have the following types: humid tropics type (YBX3-TH), dry tropics type(YBX3-TA), outdoor type (YBX3-W), outdoor medium-anticorrosion type (YBX3-WF1) and outdoor humid type (YBX3-THW),outdoor dry tropics type (YBX3-TAW), indoor tropics type (YBX3-T),outdoor tropics type (YBX3-TW).

● Exd-symbol Exd I Mb, ExdⅡAT4 Gb, ExdⅡBT4 Gb

Category I: surface highest temperature no higher than 150℃ (when coal dust may cover the motor surface), no higher than 450℃ (when coal dust will not cover the surface or some protection work has been done to prevent the coal dust accumulation)

Category Ⅱ: surface highest temperature no higher than T1(450℃), T2(300℃), T3(200℃), T4(150℃); Terminal box with three or six terminals for rubber jacket cable (plastic cable) and steel cable.

Ambient temperature:－15℃~35℃ in coal mine and －15℃~40℃ in plant.

● High efficiency IE3

Rating voltage: 380V,660V,380/660V 50Hz (for Exd-symbol Exd I and frame size 80-355)

660V/1140V 50Hz (for Exd-symbol Exd I and frame size 112-355)

380V, 660V, 380/660V 50Hz & 400V, 415V, 440V, 460V, 480V, 690V 60Hz (for Exd-symbol ExdⅡ)

Ideal for the coal mine where methane and coal dust may be present (Exd I) and dangerous explosion areas(Ex dⅡAT4,dⅡBT4)in the plant with the class ⅡA ⅡB and temperature T1-T4 flammable gas.
