YBE2/YBE3 Series High-Efficiency Explosion-Proof Motors (380 V)
156-9170-8999
Introduction to the YBE3 Series High-Efficiency Explosion-Proof Motors
The YBE3 series high-efficiency explosion-proof motors are high-efficiency flameproof three-phase asynchronous motors. They constitute SIMO’s fundamental series of totally enclosed, self-ventilated, squirrel-cage, high-efficiency flameproof three-phase asynchronous motors, independently developed and manufactured by SIMO Motor. Their efficiency complies with Grade 2 energy efficiency per GB18613-2012 “Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Small and Medium Three-Phase Asynchronous Motors”.
Motor Advantages
This series offers excellent performance, safe and reliable operation, and lower vibration and noise levels than comparable products, meeting environmental protection requirements.
Application Fields
Suitable for hazardous areas classified as Zone 1 and Zone 2 in explosive atmospheres. Widely applied across industries including petrochemicals, coal mining, metalliferous mining, ports, power plants, and mechanical engineering, to drive various general-purpose machinery—such as fans, compressors, feedwater pumps, crushers, hoists, centrifuges, machine tools, and transport equipment—making them the ideal driving solution.
