YBX5 series high-efficiency flameproof permanent magnet synchronous motors use SKF bearings, high-performance silicon steel sheets, and ultra-high coercivity rare earth permanent magnet materials. The products have the advantages of high efficiency and energy saving, high power density, fast response speed, low temperature rise, low noise, low vibration, and constant torque output in the entire speed range. The energy efficiency level reaches above the first-level energy efficiency, reaching the international advanced level of similar products. This series of products is widely used in various equipment such as fans, pumps, compressors, belt conveyors, etc. in the fields of electricity, petroleum, metallurgy, textiles, and building materials. In dangerous environments where flammable substances exist, high-efficiency flameproof permanent magnet synchronous motors are key equipment. These motors are designed to prevent the ignition of explosive atmospheres to ensure personnel safety and the integrity of industrial processes.
