Introduction

The YB2-H series of the explosion-proof three-phase induction motors is a completely enclosed fan-cooled induction motor of the squirrel-cage type. The motors are designed and manufactured according to national standards for electrical equipment in explosive working environments and are flameproof, high performing, and quiet. The squirrel cage motors drive marine machinery, such as pumps, ventilators, separators and hydraulic machines in working conditions where explosives or hazardous materials are present. The motors are in accordance with the following standards:
IEC60034    Rotating electrical machines
IEC60068   Basic environmental testing procedures
IEC60072   Dimensions and output ratings for rotating electrical machines
IEC60092   Electrical installation in ships

Construction
1. IP44 or IP56 (TEFC) protection
2. Cylindrical shaft extension. B3 and B35 motors with two shaft extensions are available upon request, but the second shaft extension can only transmit a rated output with direct coupling. The shaft is made of high grade steel No 45.
3. Terminal box is in full conformity with IEC publication 60034-8. Clearance between two neighboring conducting parts is not less than 8mm and all creepages is not less than 12mm. An extra terminal is provided inside the box for grounding.
