The YB2 and YBX2 Series High-Voltage Explosion-Proof Three-Phase Asynchronous Motors (Frame size 355-560) are high-end products developed by combining advanced foreign technology with our company’s long-standing successful experience in producing high-voltage medium-sized motors. These motors are designed using the latest design methods and materials, and incorporate the results of our research and development.

This series of motors complies with the following standards:

• GB 755-2008 "Rotating Electrical Machines - Rating and Performance"
• GB 3836.1-2010 "Explosive Atmospheres - Part 1: General Requirements"
• GB 3836.2-2010 "Explosive Gas Atmospheres - Part 2: Equipment Protected by Flameproof Enclosures ‘d’"

The explosion-proof marking is ExdIIBT4 Gb, suitable for use in II Class B areas, with a temperature classification of T4 and a protection level of Gb. This motor can replace ExdIIAT4 Gb products.

The YB2 and YBX2 Series motors feature excellent explosion-proof performance, high reliability, compact structure, high efficiency, energy-saving, safety, environmental friendliness, low vibration, low noise, and easy installation and maintenance. These motors represent a new generation of high-voltage explosion-proof three-phase asynchronous motors and are a replacement for the YB560-710 series (IC511 air-cooled structure) high-voltage explosion-proof three-phase asynchronous motors.

They are ideal for driving various general-purpose machinery, such as compressors, water pumps, crushers, winches, centrifuges, cutting machine tools, transportation machinery, and other equipment. Whether used indoors or outdoors, in high-altitude or humid climates, the YB2 and YBX2 Series High-Voltage Explosion-Proof Three-Phase Asynchronous Motors provide exceptional driving power and have earned the trust and praise of users.
