Product Details

Brief Introduction

 

Engineered for enhanced dielectric integrity, this explosion proof AC motor integrates advanced electromagnetic wire technology and structural safeguards to prevent inter-turn faults in hazardous environments.

 

Core Insulation Systems:

Thermal-Class Wire Selection: Utilizes F/H-class modified polyester (QZ(G)-155) and polyester-imide (QZY-180) windings, resisting thermal aging at  continuous operation.

Mechanical Stress Mitigation: Reinforced slot liners and vacuum pressure impregnation (VPI) eliminate abrasion risks from vibration or loose windings.

Environmental Defense: IP55-sealed construction blocks moisture/chemical ingress, while corrosion-resistant enamel prevents hydrolysis in humid conditions.

Electromagnetic Stability: Harmonic-resistant winding configuration suppresses voltage spike damage from frequent starts/stops or VFD harmonics.

 

Manufacturing protocols include:
• Strict needle-hole tests ensuring uniform enamel thickness per IEC 60317
• surge comparison testing validating inter-turn insulation strength
• Optimized slot fill rate minimizing thermal hotspots and mechanical stress
• Anti-fretting coatings on winding ties preventing micro-abrasion

 

The 132-frame motor executes:

Real-time thermal monitoring via embedded PT100 sensors

Accelerated aging simulations for thermal cycles

Partial discharge detection terminals for predictive maintenance

Ground-wall insulation rated for 3kV RMS withstand voltage

 

Certified for Zone 1/21 explosive atmospheres (chemical/petrochemical), explosion proof AC motor extends service life through synchronous protection against thermal degradation, electromagnetic stress, and environmental contaminants. Excludes lower-class insulation materials like standard polyester (QZ-130) or acetal wires.
