Why YKS Series High Voltage Motors are the Preferred Choice for Global Heavy Industry

In demanding environments where air quality is poor or ambient temperatures are excessive, standard air-cooled motors often struggle with overheating and internal contamination. This is where the YKS Series (Air-to-Water Cooled) High Voltage Motors excel.

At Changsha Changli Electric, our YKS series is engineered to provide stable power output under conditions that would compromise other motor types.

1. The Power of IC81W Cooling Technology

The defining feature of the YKS series is its IC81W cooling system. Instead of relying on ambient air to cool the internal components, the motor uses a top-mounted air-to-water heat exchanger.

• Contamination Protection: Since the internal air circulates in a closed loop, dust, salt spray, and corrosive gases from the external environment (common in Middle Eastern oil fields or Southeast Asian coastal plants) cannot enter the motor.
• Low Noise: Water-cooling significantly reduces the aerodynamic noise typical of large fan-cooled motors, making it ideal for noise-sensitive installations.

2. Built for High-Power Applications

The YKS series is designed for heavy-duty drive requirements, commonly powering:

• Centrifugal Pumps in water treatment and irrigation.
• Fans and Blowers in large-scale power generation.
• Compressors and Crushers in South American mining operations.

3. Key Technical Specifications

Our YKS motors are manufactured to meet and exceed IEC standards, offering:

• Voltage Range: 3kV, 6kV, 10kV, and up to 13.8kV.
• Protection Class: IP54 or IP55 (Superior dust and water resistance).
• Insulation Class: Class F with Class B temperature rise for enhanced safety margins.
• Efficiency: Optimized electromagnetic design to ensure high efficiency and low vibration.

4. Durability in Extreme Climates

For our clients in Brazil, Chile, and the UAE, the YKS series offers a critical advantage: Independence from Ambient Air Temperature. As long as a cooling water source is available, the motor can maintain optimal operating temperatures even when the outside air exceeds 45°C.

The Changli Electric Advantage: Customization & Reliability

As a specialized technical expert at Changsha Changli Electric, Lisa and our engineering team ensure that every YKS motor is tailored to the specific mechanical load requirements of the client.

• VPI Process: All YKS windings undergo Vacuum Pressure Impregnation to ensure long-term dielectric strength.
• Rigorous Testing: Every unit is subjected to load tests and pressure tests on the water cooler to ensure zero leakage and maximum heat transfer.

Released June 21, 2026, YKS series high voltage water-cooled alternating current motors, a premium type of a c motor and mainstream electric motors ac manufactured by Changsha Changli Electric, perfectly solve overheating and contamination defects of conventional air-cooled ac motors in extreme industrial settings.

The core advantage of these alternating current motors lies in IC81W and IC86W closed air-to-water cooling systems. Different from ordinary a c motor products relying on ambient air for heat dissipation, the internal air of YKS ac motors circulates in a fully closed loop, blocking dust, salt fog and corrosive gas from invading the electric motors ac. Meanwhile, water cooling eliminates fan-induced loud noise, making the alternating current motor fit noise-sensitive production workshops.

Built for heavy-duty high-power drive, this range of alternating current motors widely serves centrifugal pumps, power plant blowers and mining crushers, catering to global users of a c motor in the UAE, Brazil, Chile and Southeast Asia. The ac motors cover frame sizes H355-H1000, power from 160kW to over 10,000kW, and voltages ranging from 3kV to 13.8kV. These electric motors ac reach IP54–IP66 protection grades, adopt Class F/H insulation with Class B temperature rise, and feature optimized electromagnetic design for high efficiency and low vibration. All alternating current motors comply with IEC, GB and GOST standards, with optional NEMA certification. Even when ambient temperature exceeds 45°C, the a c motor can run steadily with continuous cooling water supply. Standard IMB3 horizontal mounting is provided, and customized installation structures are available for all ac motors.

Changli Electric guarantees long-term stability of each alternating current motor. Windings of every electric motors ac adopt VPI vacuum pressure impregnation to maintain stable dielectric strength. All finished a c motor units undergo load and water cooler leakage tests to ensure reliable heat exchange. The professional engineering team customizes ac motors according to clients’ unique load demands.

In conclusion, with sealed cooling, wide power and voltage range, strong environmental resistance and strict quality control, YKS water-cooled alternating current motors are reliable heavy-load electric motors ac and top-tier a c motor solutions for harsh heavy industry worldwide.
