YBX4 Series Flameproof Three Phase Asynchronous Motor

YBX4 series of flameproof three-phase asynchronous motors are the basic series of fully enclosed, fan-cooled, squirrel cage and flameproof three-phase asynchronous motors developed by our company. And it has the characteristics of excellent performance, safe and reliable use, lower vibration and noise than similar products, and meets environmental protection requirements. The energy efficiency ratings of the motors are YBX4-IE4.

This series of motor is mainly applied in areas with mixed dangerous and explosive gases, such as underground coal mine (non- excavation working faces), petroleum, chemical engineering, mining industry, metallurgical industry, power and natural gas areas which contains gases like methane.

The Difference Between YBX3 and YBX4 Explosion-proof Motors

The main difference between YBX3 and YBX4 explosion-proof motors is the different energy efficiency grade standards. The YBX3 energy efficiency grade conforms to the GB18613-2020 energy efficiency grade 3 standard, which is IE3, and the YBX4 energy efficiency grade conforms to the GB18613-2020 energy efficiency grade 2 standard, which is IE4. Compared with IE3, the cost of IE4 has also increased significantly.
