Title

YBX4-280S-2 High-Efficiency Explosion-Proof Three-Phase AC Motor

Brief Introduction

Designed specifically for hazardous environments, this ATEX-certified motor features an advanced bearing system engineered to uphold flameproof integrity under demanding operational conditions.

Explosion-Proof Bearing Design Highlights:

• Dual Flame-Path Interfaces: Utilizes both cylindrical shaft-bearing surfaces and flat end-shield junctions to effectively isolate internal components from external explosive atmospheres in frame sizes 280 and above.
• Precision Radial Clearance Management: Accurately machined bearing seats maintain minimal gaps below ignition limits, while accommodating temperature-induced expansion.
• Dynamic Sealing Mechanism: Equipped with integrated oil injection channels and purge ports to prevent buildup of combustible materials in high-frequency operational settings.
• Non-Invasive Fastening System: Captive bolts secure the end-shields without penetrating the motor housing, preserving the structural integrity of the flameproof enclosure.

Key Safety Features Include:

• Anti-loosening tabs on all threaded components to prevent vibration-related disengagement
• Electrical continuity across all isolated flame-path surfaces
• Triple-verification of running clearances after final assembly
• Use of conductive grease to safely dissipate static charges

YBX4-280S-2 Frame Capabilities:

• Pressurized bearing housings that contain potential internal ignition
• Interlocking labyrinth seals to block dust and debris ingress
• Accessible ports for flame-path inspection and maintenance
• Anti-corrosion coatings applied to all critical contact surfaces

Certified for use in Zone 1/21 classified environments such as petrochemical plants and milling operations, this explosion-proof AC induction motor meets and exceeds IECEx standards. Every component within the bearing system—including end shields, caps, and shaft sleeves—is pressure-tested individually to ensure maximum safety before final assembly.

Why choose Simo Brand YBX4 series of Motor?

The YBX4 Low-Voltage Explosion-Proof Motor is equipped with a flameproof enclosure that effectively isolates internal components—such as those that may produce sparks, arcs, or excessive heat—from the surrounding explosive gas environment. This design significantly reduces the risk of ignition in hazardous areas, especially during motor startup. The motor features high-quality copper windings arranged evenly to maintain long-term operational stability and resist deformation. With strong bearing torque and quick response, the motor delivers smoother performance and operates with reduced noise levels. For specialized requirements, we also offer professional customization services tailored to your specific application needs.
