YB3-63\u2013355 Flameproof Three-Phase Induction Motors\nThe YB3-63\u2013355 series flameproof three-phase induction motors are our latest generation of products, developed on the basis of the YB and YB2 series by incorporating advanced technologies in electromagnetic design, manufacturing processes, and materials. These motors offer the advantages of high efficiency and energy savings, generous temperature rise margin, long service life, excellent performance, low noise, advanced flameproof construction, high reliability, and ease of operation and maintenance.\n
\nThe efficiency of this series complies with GB 18613-2006 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Small and Medium Three-Phase Induction Motors, meeting Energy Efficiency Level 2. The power ratings and installation dimensions align with IEC standards and are identical to those of the YB and YB2 series motors.<\/p>\n
This series conforms to:
\n\nGB 755-2008 Rotating Electrical Machines \u2013 Rating and Performance
\n\nJB\/T 7565.1-2011 *Technical Specifications for YB3 Series Flameproof Three-Phase Induction Motors (Frame Sizes 63\u2013355)*
\n\nThe explosion-proof performance complies with:\n
\n\nGB 3836.1-2010 Explosive Atmospheres \u2013 Part 1: Equipment \u2013 General Requirements
\n\n\nGB 3836.2-2010 Explosive Atmospheres \u2013 Part 2: Equipment Protection by Flameproof Enclosure \u201cd\u201d
\n\n\nThe motors are designed as flameproof types ExdI Mb, ExdIIAT4 Gb, and ExdIIBT4 Gb, suitable for hazardous locations in underground coal mines (excluding coal face excavation areas) and factory environments with explosive gas atmospheres of Classes IIA and IIB, temperature groups T1\u2013T4.<\/p>\n
