I. Product Overview The YBX4 series ultra-high-efficiency flameproof three-phase asynchronous motors are energy-efficient power equipment specifically developed for explosion-proof industrial applications. Featuring a fully enclosed design with self-cooling fans and a squirrel-cage structure, these motors have been awarded the "Energy Efficiency Star" title by the Ministry of Industry and Information Technology (MIIT) through their proprietary core technologies and hold four utility model patents. Achieving international IE4 (GB1) energy efficiency standards, they not only fully comply with national policies on energy conservation, carbon reduction, and equipment modernization but also deliver dual breakthroughs in explosion protection and energy efficiency. These motors can directly replace YBX3 series units without additional modifications, making them widely compatible with various flammable and explosive industrial environments to ensure safe and sustainable production operations for enterprises. II. Core Advantages 1. Ultra-high energy efficiency for cost savings and carbon reduction: The unit achieves IE4-level energy efficiency, complying with the GB18613–2012 Grade 1 efficiency standard, with an efficiency improvement of approximately 1.2% compared to the YBX3 series. Leveraging precision electromagnetic and structural design, it precisely controls various energy losses. Taking the 220kW model as an example, continuous long-term operation results in annual electricity savings exceeding 30,000 kWh, helping enterprises reduce energy consumption costs and carbon emissions—aligning with national carbon peaking and carbon neutrality goals—and meeting the equipment upgrade requirements in key sectors. 2. Reliable explosion-proof design with comprehensive safety: Strictly compliant with GB/T 3836.1-2021 and GB/T 3836.2-2021 standards, featuring explosion-proof ratings of ExdbⅡAT4Gb, ExdbⅡBT4Gb, and ExdbⅡCT4Gb. It ensures safe operation in non-coal mine gas environments classified as Class II A/B/C and Grade T1-T4 explosive gas zones, eliminating ignition risks at the source and eliminating safety hazards in flammable and explosive conditions. This guarantees continuous and stable production while significantly reducing downtime losses caused by equipment failures. 3. Stable and durable, with hassle-free operation and maintenance: It features an insulation class of F (assessed based on Class B temperature rise), a standard IP55 protection rating, a compact design, smooth operation, and lower vibration and noise levels compared to similar products. Manufactured from high-quality materials using precision engineering, it withstands harsh operating conditions such as high temperatures, high humidity, and dust exposure, offering a longer service life. The units below model 225 employ sealed, maintenance-free bearings, while those above model 225 are equipped with oil injection nozzles, facilitating easy maintenance and minimizing downtime losses. Recognized as an Industrial Excellence Award winner, its quality is widely acknowledged. 4. Easy adaptation and rapid upgrade: The installation dimensions are identical to those of the YBX3 series, supporting multiple mounting methods including IMB3 (horizontal) and IMB5 (flange). It allows direct replacement and upgrade without modifying the equipment foundation, significantly reducing construction time and lowering replacement costs. The junction box comes standard with explosion-proof glanded inlet terminals and features optional threaded ports to accommodate various on-site wiring requirements, addressing the challenges of difficult model selection and poor compatibility in non-standard applications. III.

Corrosion-resistant configurations are available upon request, ensuring suitability for complex and harsh operating conditions. IV. Application Scenarios Widely used in industries such as petroleum and natural gas, chemical, mining, metallurgy, power generation, textiles, grain and oil processing, papermaking, and pharmaceuticals, this solution is particularly suitable for projects requiring "conventional explosion protection combined with cost-effective energy efficiency." It serves as the core power supply for equipment like pumps, fans, and compressors, effectively addressing industry challenges in explosion-proof environments—including insufficient energy savings, complex compatibility requirements, and intricate maintenance processes. Capable of adapting to non-standard operating conditions, it can be rapidly deployed without additional modifications, enabling enterprises to achieve green and efficient production. V. Certification and Assurance 1. Authoritative Certification: Possesses explosion-proof certification, CQC energy efficiency certification, and CCC certification, complying with domestic market access requirements and relevant industry standards. It successfully passes various safety inspections and project acceptance processes, meeting the advanced energy efficiency requirements for key energy-consuming products and equipment. 2. Delivery Guarantee: Standard power unit/basis delivery takes 2–4 weeks; customized requirements can be negotiated to ensure project timelines remain unaffected. 3. Professional Warranty: An 18-month warranty begins from the date of shipment. For non-human-induced damage, repairs and part replacements are provided free of charge, supported by a professional technical team offering comprehensive technical assistance to eliminate any concerns during enterprise operation.
