Title:
YKK 3556-4 Three-phase Asynchronous Heavy Duty Motor
Brief Introduction
The SIMO YKK3556-4, a 6000V three-phase asynchronous heavy duty motor, emerges as a flexible and dependable power option for a wide range of high-pressure industrial fields. Designed to perform reliably in tough working environments, it steadily delivers superior operational results while bringing substantial energy-saving advantages, thus becoming a go-to choice for vital industrial processes globally.
In the cement production sector, this motor has been effectively installed to drive large ball mills at a prominent cement manufacturing facility in Central China. Working in a setting filled with heavy dust and constant high-load demands, the heavy duty motor's IP54 protection grade successfully keeps dust out. Its sophisticated IC611 cooling mechanism maintains steady thermal performance even when the surrounding temperature hits 39°C. With an impressive 92.6% efficiency rate, it has helped the facility cut down annual electricity use by more than 15,000 kWh compared to the obsolete motor it replaced. Moreover, its steady and powerful torque output ensures the high-inertia ball mill starts smoothly, avoiding expensive production halts due to startup issues.
For metallurgy, it powers blast furnace exhaust fans at a Northeast China steel mill. F-class insulation withstands high temperatures, while a 0.86 power factor reduces reactive loss, slashing monthly utility costs by 9% during 24/7 operation.
In high-altitude water supply, it serves a Southwest China plateau pump station (2800m+). Its enhanced insulation adapts to thin air, ensuring stable water pressure for 50,000+ residents even at -15°C winters.
CE-certified and backed by SIMO's global service network, it's a trusted solution for cement, metallurgy, and plateau water supply sectors.
