I. Product Overview The YBX5 series ultra-high efficiency flameproof three-phase asynchronous motor is an upgraded and iterated version of the YBX4 series, and also a benchmark product leading the industry's high-efficiency flameproof technology. It adopts a fully enclosed, self-cooling, squirrel-cage structure. Relying on core technological breakthroughs such as new winding structure and optimized stator and rotor design, it achieves a major breakthrough in energy efficiency exceeding the international highest IE5 level, complying with the GB18613-2020 Level 1 energy efficiency standard, and is selected as a representative product of the relevant standards in the central enterprise "Leader" list. The product has the advantages of extreme energy saving, reliable flameproof performance and convenient adaptation. It can directly replace the YBX3 and YBX4 series motors without additional modification, and is widely applicable to high-end flameproof industrial scenarios, providing core power support for enterprises to achieve safe, efficient and green production. II. Core Advantages 1. Super Level 1 Energy Efficiency, Leading Energy Saving: The energy efficiency reaches the international IE5 level, complying with the GB18613-2020 Level 1 energy efficiency standard. Compared with the YBX4 series, the efficiency is further improved by about 1.5% or more, and 3% or more higher than that of traditional motors. Relying on refined manufacturing processes such as new winding structure and copper rotor casting, it accurately reduces various motor losses. Taking the 160kW model as an example, it can save more than 45,000 kWh of electricity per year under long-term continuous operation. Up to now, the total output of the whole series has reached 2.21 million kilowatts, which can save about 265 million kWh of electricity for the country every year. It helps enterprises greatly reduce energy consumption costs, practice the national "dual carbon" goal, and adapt to the energy-saving transformation of high-energy-consuming enterprises and the equipment renewal needs of key fields. 2. Full-Scope Flameproof, Safety Upgrade: Strictly following the GB/T3836.1-2021 and GB/T3836.2-2021 standards, the flameproof mark covers ExdbⅡAT4Gb, ExdbⅡBT4Gb and ExdbⅡCT4Gb, with an additional dust explosion-proof certification. It can be customized to ExdⅡCT4Gb (hydrogen level), suitable for ⅡA/ⅡB/ⅡC class, T1～T4 level explosive gas places and high-dust scenarios in non-coal mine gas environments. It avoids ignition source risks from the source, eliminates potential safety hazards in flammable and explosive environments, ensures continuous and stable production, greatly reduces fault shutdown losses, and adapts to more harsh flameproof working conditions. 3. Stable and Durable, More Economical Maintenance: The insulation class is Class F (assessed according to Class B temperature rise), and the temperature rise margin is 15~20 Kelvin higher than that of YBX4. The protection class is IP55 as standard, and IP56/IP65 is optional. It has a compact structure and stable operation. The vibration value of 2P motor is as low as 1.5 mm/s, and the noise is controlled below 85 decibels, which is better than similar products. Adopting high-quality materials and precision manufacturing processes, it is suitable for harsh working conditions such as high temperature, high humidity, strong corrosion and dust, and has a longer service life; models above 160 can be equipped with non-stop oil injection and drainage devices, motors below 225 frame adopt sealed maintenance-free bearings, and those above 225 are equipped with oil nozzles, which are convenient for maintenance, further reducing shutdown losses. The quality has passed strict industry verification and is highly recognized by the market. 4. Seamless Adaptation, Rapid Upgrade: The installation size is completely consistent with the YBX3 and YBX4 series, supporting various installation methods such as IMB3 (horizontal), IMB5 (flange), etc. It can be directly replaced and upgraded without modifying the equipment foundation, greatly shortening the construction period, reducing the replacement cost, and effectively improving the willingness of enterprises to upgrade products. The junction box is equipped with flameproof gland inlet as standard, and can reserve thread ports on demand to adapt to different on-site wiring needs. At the same time, it can be customized with special configurations such as -55℃ ultra-low temperature start-up and anti-corrosion coating, perfectly solving the pain points of "cumbersome adaptation and poor customization" in high-end flameproof scenarios.
