Technical Advantages

Your operations benefit from four core innovations. The increased safety rotor/stator configuration limits hot spots during normal operation and overload conditions. Integrated top-mounted heat exchangers dissipate thermal energy efficiently without external coolant systems. Large-capacity terminal boxes feature extended creepage distances meeting Ex e requirements for 11,000V applications. Premium SKF bearings reduce vibration to under 2.8mm/s while F-class insulation withstands continuous 155°C temperatures. This combination delivers 15% longer service life compared to standard explosion-proof designs.

Production Process

Every motor undergoes rigorous manufacturing stages. Stator cores utilize silicon steel laminations with laser-cut precision. Copper windings receive triple VPI impregnation cycles for void-free insulation. Air-air coolers feature aluminum fins with 0.8mm spacing for maximum heat transfer. Rotor balancing achieves G2.5 grade standards across all speed ranges. Final assemblies pass 100% hipot testing at 2.5x rated voltage plus routine vibration analysis before shipment.

Industry Applications

YAKK motors power critical equipment across hazardous sectors:

· Petrochemical: Compressors and pumps handling flammable hydrocarbons in Zone 1 areas

FAQ

Q：What regular maintenance items for YAKK air-air-cooled high voltage increased safety motor?

A：Clean heat exchanger fins monthly to prevent blockage. Verify air duct sealing integrity quarterly. Test insulation resistance and PT100 sensors semi-annually. Never modify terminal boxes or internal components. Inspect cooling fans daily for abnormal sounds.

Q：What is the difference between YAKK increased safety motor and YB2 flameproof high voltage motor?

A：YAKK uses Ex e principles to prevent ignition sources, while YB2 contains explosions through flameproof gaps. YAKK suits equipment without arc risks; YB2 handles broader hazards. Cooling methods differ: closed air-air versus open fan systems. YAKK dimensions exceed YB2 due to integrated heat exchangers.

Q：What advantages does air-air cooling IC611 have compared with water-air cooling IC81W?

A：Eliminates pipelines, pumps, and water treatment infrastructure. Removes leakage, scaling, and freezing concerns. Ideal for water-scarce regions or strict anti-leakage sites. Installation complexity drops significantly with simpler inspection routines.

Q：What are the core structural features of YAKK increased safety motor?

A：Special rotor/stator design minimizes spark potential. Top-mounted air-air exchangers enable closed-loop heat dissipation. VPI corona-resistant insulation handles prolonged high voltage stress. Oversized terminal boxes provide safe creepage distances preventing discharge.

Q：What is YAKK air-air-cooled high voltage increased safety motor explosion-proof symbol?

A：Standard marking is Ex e ⅡT4 Gb, certifying Zone 1 and Zone 2 compatibility per GB 3836.3 increased safety standards for flammable gas environments.
