Pain Points vs. Solutions

Your Challenges:

· Air-cooled motors overheat in enclosed workshops with poor ventilation

· Excessive fan noise disrupts operations in sound-restricted areas

· Dust accumulation clogs air ducts, causing frequent maintenance shutdowns

· Ambient temperature fluctuations reduce motor reliability during peak seasons

Our Water Cooling Solutions:

· Internal water coolers maintain stable temperatures regardless of external conditions

· Fanless design reduces operational noise by 60-70%

· Sealed housing prevents dust infiltration, extending service intervals

· Consistent heat dissipation enables full-load operation in 45℃ environments

Technical Advantages

The YKS series provides 20-25% more power density than the regular air-cooled motors. Our 800 frame size hits 6300 kw power - no more parallel motor options. The small design allows a simplified system architecture and fewer possible sources of failure.

The cooling system consists of corrosion-resistant aluminum alloy cores with watertight sealing. Salt spray testing for 1500+ hours confirms reliable performance for heat exchangers in coastal and chemical settings. Operating temperature range: -25℃~45℃ up to altitude 2000 meters

The direct heat transfer to the liquid allows thermal efficiency to be higher than air cooled counterparts. The temperature increase is negligible even in heavy-duty continuous cycles, therefore preserving the winding insulation and increasing the life of the motor by 30-40%.

Production Process

FAQ

Q：What is YKS water-cooled high voltage motor?

A：YKS series are box-type water-cooled high voltage three-phase squirrel-cage aSynchronous Motors with rated voltage of 6kV/10kV. A built-in water cooler inside the frame dissipates heat through circulating cooling water without exposed cooling fans. It is suitable for closed, dusty and noise-restricted workshops, widely used for high-power continuously-operated equipment.

Q：What are the core advantages of water cooling compared with air-cooled HV motors?

A：Higher cooling efficiency with smaller size and lower temperature rise under the same power. No axial cooling fan, greatly reducing operating noise. No dust accumulation in air ducts, suitable for severe dusty conditions such as cement, chemical and mining industries. Heat dissipation is not affected by ambient temperature, enabling stable full-load operation in high-temperature workshops. Better overall tightness to avoid winding short circuit caused by dust accumulation.

Q：Which industries and equipment is YKS water-cooled high voltage motor applied to?

A：Mainly applied in thermal power, nuclear power, chemical, metallurgy, cement and large pump stations, matched with boiler induced draft fans, circulating water pumps, main air compressors, vertical raw material mills and large steel rolling equipment. Ideal for underground machine rooms, closed workshops and areas with strict noise and dust control requirements.

Q：What causes abnormal overheating of YKS water-cooled motor?

A：Common causes include insufficient cooling water flow or excessively high inlet water temperature, scale accumulation inside water cooler blocking pipeline and reducing heat exchange efficiency, incompletely opened water valves or folded pipelines causing flow restriction, long-term motor overload operation, and water circuit leakage leading to dry burning of the cooler.

Q：What regular maintenance items are required for YKS water-cooled high voltage motor?

A：Test cooling water flow and temperature difference regularly, conduct acid cleaning to remove scale periodically. Check water cooler and pipe joints for water leakage. Replace bearing lubricating grease on schedule, monitor bearing temperature and vibration. Measure insulation resistance and DC resistance of high voltage windings annually. Clean high voltage terminal box and fasten terminals. Inspect frame tightness during shutdown to avoid water vapor penetrating windings.
