AC Induction Motor For Sale

Title:

YBX4-280S-2 Explosion-proof High Efficiency 3 phase AC Motor

Brief Introduction

Engineered for explosive atmospheres, this ATEX-certified motor integrates specialized bearing systems to maintain flame-arresting integrity under rigorous operational conditions.

Explosion-Proof Bearing Architecture:

Dual-Interface Flame Paths: Combines cylindrical shaft-bearing interfaces and planar end-shield joints to seal internal cavities from external hazards in 280+ frame sizes.

Radial Clearance Control: Precision-machined bearing seats maintain critical gaps below ignition thresholds while accommodating thermal expansion.

Dynamic Sealing Systems: Integrated oil-injection channels with purge ports prevent combustible residue accumulation in high-cycle applications.

Non-Penetrating Fasteners: Captive bolt assemblies secure end-shields without compromising enclosure integrity, eliminating wall-piercing violations.

Critical safety implementations:
• Anti-rotation tabs on all threaded connections prevent vibration-induced loosening
• Grounding continuity across isolated flame-path surfaces
• Triple-verified running clearances post-assembly
• Conductive grease formulations dissipate static charges

The YXB4 280S-2 frame executes:

Pressurized bearing housings containing internal explosions

Interlocked labyrinth seals blocking particulate ingress

Accessible flame-path inspection ports

Corrosion-resistant coatings on critical interfaces

Validated for Zone 1/21 environments (petrochemical, milling), AC induction explosion-proof motor exceeds IECEx requirements through redundant containment barriers. All bearing system components – including end-shields, bearing caps, and shaft sleeves – undergo individual pressure testing prior to final assembly.

Main Technical Parameters

Why choose Simo Brand YBX4 series of Motor?

The YBX4 LV Explosion Proof Motor uses a flameproof enclosure to isolate electrical parts that may generate sparks, arcs, and dangerous temperatures from the surrounding explosive gas mixture. For special environments, the selection of explosion-proof motors can minimize accidents such as explosions caused by electric sparks generated when the motor is started. The copper wire can ensure that the motor works stably for a long time and is evenly arranged, so it is not easy to deform. The bearing torque is large and the response is good, so the motor works more stably and the noise is lower. If you need product customization, we also have professionals who can provide services.
