YBFBX5 Gas & Dust Ex Induction Motors

Frame pages & dimensions Back to motor finder

The YBFBX5 series of flameproof and dust ignition-proof high-efficiency three-phase induction motors covers 0.18–315 kW in 2-, 4-, 6- and 8-pole versions, frame sizes 80–355, with Ex marking Ex db IIC T4 Gb / Ex tb IIIC T130°C Db for both explosive gas and combustible dust atmospheres. The tables below list all 113 standard models; open a model for mounting dimensions and outline drawings.

Overview

Electrical performance of YBFBX5 motors (frame sizes 80–355) follows Shangli enterprise standard Q/320804KSL07-2022. Explosion protection complies with GB/T 3836.1-2021 (explosive atmospheres – general requirements), GB/T 3836.2-2021 (equipment protection by flameproof enclosures “d”) and GB/T 3836.31-2021 (equipment dust ignition protection by enclosure “t”).

With Ex marking Ex db IIC T4 Gb / Ex tb IIIC T130°C Db, the motors suit hazardous explosive gas areas in surface industry (acetylene, hydrogen, carbon disulphide and similar) and areas with combustible dust mixtures: dust, fibres and flyings; metal processing (aluminium, magnesium, titanium); agricultural products (flour, cocoa, cotton dust, flax, fibre, tobacco); forest products (paper and wood powder); synthetic materials (plastics, resins, dyes); and chemical and pharmaceutical raw materials (sodium acetate, aspirin, zinc stearate and others).

Main specifications

Frame sizes: 80–355
Output: 0.18–315 kW
Poles: 2, 4, 6 and 8
Rated voltage: 380 V; at other voltages current I = IN × 380 / U, other values unchanged
Rated frequency: 50 Hz; for 60 Hz add 6 dB(A) to the no-load noise of 2-pole frames 200–355 and 5 dB(A) for others
Cooling: totally enclosed, fan-cooled (IC411)
Ex marking: Ex db IIC T4 Gb / Ex tb IIIC T130°C Db
Environment: indoor (standard); outdoor (W), indoor humid tropical (TH), outdoor humid tropical (WTH), outdoor tropical (WT) and outdoor medium anti-corrosion (WF1) available

Model designation

Example: YBFBX5-132S2-4

Y: three-phase induction motor
BFBX: flameproof and dust ignition-proof, high efficiency
5: fifth design revision
132: shaft height 132 mm
S2: short frame, core length code
4: number of poles

Interchangeable mounting dimensions

YBFBX5 motors share the mounting dimensions of YBX3, YBX4 and YBX5 flameproof motors of the same frame size, so a site that adds a combustible-dust requirement can switch to YBFBX5 without changing the feet, shaft extension or flange.

Values at 380 V, 50 Hz; efficiency applies at 75–100% load and noise is the no-load sound pressure level. At voltages other than 380 V, current I = IN × 380 / U and other values are unchanged. For 60 Hz motors, add 6 dB(A) to the no-load noise of 2-pole frames 200–355 and 5 dB(A) for other pole numbers. Final values are those in the routine test report.
