FAQ

Q：What is the meaning of each letter in the model YXKS?

A：Y represents three-phase aSynchronous Motor; X indicates high efficiency; K denotes closed structure air circulation; S means water cooling. YXKS is a high-efficiency three-phase motor with air-water cooling closed circulation.

Q：What cooling structure does YXKS motor adopt?

A：It uses an independent air-water closed circulation cooling system with a built-in water cooling heat exchanger. Internal air circulates to remove heat, while cooling water carries heat out of the motor, providing stable heat dissipation under heavy load and low speed conditions.

Q：What energy efficiency standard does YXKS air-water-cooled motor meet?

A：The entire series achieves IE4 ultra-high efficiency grade through optimized silicon steel sheets and copper windings that reduce iron and copper losses.

Q：What standard parameters of protection grade, insulation class and voltage are available?

A：Standard configurations include IP54/IP55 protection, Class F anti-harmonic insulation, S1 continuous working system, with common voltage grades of 3kV, 6kV, 10kV, and support for customized voltages.

Q：What working conditions and industries are YXKS motors suitable for?

A：These motors excel in high temperature, dusty, poorly ventilated, and heavy-load environments—widely used in thermal power, metallurgy, cement, and chemical industries with large fans, water pumps, ball mills, and compressors.
