YBX4-132S1 Dust Ignition Proof Motor High Efficiency 3 phase

Title:

YBX4 Explosion-proof High Efficiency 3 phase AC Motor

Brief Introduction

YBX4 series super three-phase asynchronous dust ignition proof motor is the upgraded series of YBX3, which has more higher efficiency. The cooling mode is IC411, the explosion-proof mark is ExdⅠMb and ExdⅡBT4 Gb, and it can replace ExdⅡAT1Gb, ExdⅡAT2 Gb, ExdⅡAT3 Gb, ExdⅡAT4 Gb, ExdⅡBT1Gb, ExdⅡBT2 Gb and ExdⅡBT3 Gb.   

Rated at 5.5 kW and 50 Hz, it operates on 380V AC, drawing 10.4A current. Boasting a high efficiency of 90.9% and a power factor (cosφ) of 0.88, it runs at 2900 r/min (2-pole design), delivering reliable performance for industrial applications.

Certified with the explosion-proof marking Exd [ib] IIB T4 Gb, it meets safety standards for hazardous environments, with the certification number CNEx20.5105. Designed for a max ambient temperature of 40°C and altitude up to 1000m, it uses SKF 6208-2Z/C3 bearings (both drive and non-drive ends) and has a 155(F) insulation class, ensuring durability.

With an IP rating (likely IP55) and B3 mounting, it weighs 85 kg. Produced in December 2025 (serial number J26012007001), this dust ignition proof motor combines efficiency, safety, and robustness-ideal for explosion-prone industrial settings like petrochemical, mining, or chemical sectors.

Main Technical Parameters

Why choose Simo Brand YBX4 series of Motor?

High Efficiency & Energy Savings

Boasting a 90.9% efficiency (surpassing standard motor levels), the YBX4 series cuts long-term energy costs significantly-critical for continuous industrial operations. Its 0.88 power factor also reduces reactive power loss, optimizing grid performance.

Flameproof Safety

Certified with Exd [ib] IIB T4 Gb (CNEx20.5105), it's engineered for hazardous environments (e.g., petrochemical, mining). This flameproof design prevents internal sparks/explosions from igniting external flammable atmospheres, meeting strict safety regulations.

Durability & Reliability

Equipped with SKF 6208-2Z/C3 bearings and 155(F) insulation class, it handles 40°C ambient temperatures and 1000m altitude. The robust build (85kg, B3 mounting) ensures stable operation under heavy loads, minimizing downtime.

Versatile Application

With 5.5kW power and 2900r/min speed, it suits diverse industrial equipment (pumps, fans, conveyors). The WF1 rating also adapts to specific working conditions, adding flexibility.

Trusted Quality

Produced by Xi'an Taifu Simot (a reputable motor manufacturer), the YBX4 series follows the Q/XD B10.262-2022 standard, backed by consistent after-sales support (4000291177).
