Challenges and Answers

Problem: Premature motor winding breakdown from dust and corrosive gas ingress in open-air cooled systems.

Solution: Full-frame sealing avoids damage to crucial internal components by environmental pollutants.

Problem: Conventional motors lose cooling efficiency due to high ambient temperature and sandstorms.

Solution: Isolated internal air circulation removes heat dissipation from the outside weather conditions.

Challenge: Winding failures are frequent, leading to increased maintenance costs and production downtime.

Solution: Less dust build-up reduces the likelihood of insulation degradation and extends service life.

The problem: too much noise pollution that threatens worker safety and facility compliance.

External cooling fan arrangement greatly reduces total acoustic emissions.

FAQ

Q：What is YKK air-air-cooled high-voltage motor?

A：YKK series are enclosed box-type high-voltage three-phase squirrel-cage asynchronous motors equipped with built-in air-to-air heat exchangers. Internal hot circulating air exchanges heat with external cold air for cooling. The standard voltage is 6kV/10kV. The fully sealed structure prevents dust and moisture from entering the stator winding chamber.

Q：What advantages does YKK air-air cooling motor have over open air-cooled HV motors?

A：Fully sealed frame stops dust and corrosive gas from invading windings. Independent internal air circulation operates free from high ambient temperature interference. External cooling fan reduces overall motor noise. Less dust accumulation greatly lowers insulation breakdown risks. Higher protection class allows outdoor installation.

Q：Which industries and equipment are the products suitable for?

A：Widely used in cement, mining, thermal power, chemical, metallurgy and coal industries. Commonly matched with vertical raw mills, large induced draft fans, main circulating water pumps, air compressors and belt drive equipment. Ideal for dusty, corrosive environments.

Q：What causes high temperature rise of YKK air-air cooled motor?

A：Common causes include dust clogging heat exchange fins, faulty external cooling fan, long-term overload operation, poor workshop ventilation, or blocked internal circulation air ducts hindering normal hot air flow.

Q：What are the key regular maintenance items of the product?

A：Blow dust off cooler fins regularly. Inspect cooling fan operation and bearing temperature. Refill bearing grease on schedule. Test winding insulation resistance during shutdown. Check frame sealing strips. Tighten high voltage terminals to prevent overheating.
