Brief Introduction

SIMO YBX3 series represents a premium lineup of flameproof three-phase induction motors engineered for safe, stable operation within hazardous industrial environments. Built in strict accordance with JB/T 12628-2016 standards and certified Ex db IIBT4 Gb explosion-proof rating, these motors are designed to withstand atmospheres containing flammable gases and vapors, making them an ideal power solution for petroleum, chemical engineering, pharmaceutical manufacturing and coal-related industries. Among the most popular specifications in this range is the motor 5.5 kw 3000 rpm variant, model YBX3-132S1-2, with a rated speed of 2920 r/min, closely matching the 3000 rpm synchronous speed.

Reliability and operational safety stand at the core of the YBX3 design. The whole unit adopts robust cast iron housing with IP55 ingress protection, effectively blocking dust, splashing water and particulate pollutants. Class F insulation (thermal resistance up to 155°C) supports S1 continuous-duty operation, allowing non-stop long-hour production without premature aging of windings. High-quality C3 clearance bearings are fitted on both drive and non-drive ends, lowering friction noise and extending service life. The motor structure strictly complies with flameproof enclosure requirements; any internal electric arc or short-circuit will be contained inside the casing and prevented from igniting surrounding dangerous mixtures. Operators can deploy the motor 5.5 kw 3000 rpm safely in Zone 1 and Zone 2 explosive hazardous areas without safety concerns.

Energy efficiency is another outstanding advantage of YBX3 motors. Optimized electromagnetic design cuts core loss and copper loss significantly. The motor 5.5 kw 3000 rpm achieves an efficiency of 89.2% at rated working conditions, with a power factor of 0.88. Compared with older explosion-proof motor generations, it delivers obvious electricity savings during long-term continuous running. For enterprises running dozens of motors year-round, the reduced power consumption creates remarkable long-term operational cost advantages. Standard configuration works on 380V, 50Hz power supply, and multiple mounting types including IM B3 are available to fit pumps, fans, compressors and general processing equipment.

A typical practical application can be seen with a chemical enterprise in Southeast Asia. The client needed explosion-proof drive units for process circulation pumps used in organic solvent workshops. After technical evaluation, they selected multiple sets of the motor 5.5 kw 3000 rpm YBX3-132S1-2 motors to replace outdated low-efficiency explosion-proof motors. Following more than one year of continuous field operation, the equipment maintained steady speed and low vibration. Workshop safety inspections confirmed full compliance with local explosion-proof regulations. The client recorded a noticeable drop in monthly power bills, and zero motor breakdowns occurred during the whole operation cycle. Satisfied with the performance, the buyer placed repeated orders for other production lines later.

SIMO supports flexible customization to satisfy diverse project demands. Adjustments on voltage, frequency, mounting dimensions and special coating treatments can be offered upon request. Every unit undergoes strict factory testing before shipment, and complete certification documents including explosion-proof certificates and 3C certificates are provided. Whether you need individual units of the motor 5.5 kw 3000 rpm or bulk orders of other frame sizes from the YBX3 series, we deliver consistent quality, reliable after-sales support and professional technical consultation, helping global industrial users solve power drive challenges in hazardous working environments.
