YRKK 630-8GT 3 Phase Asynchronous 6 Pole AC Motor 1800kW

Brief Introduction

The SIMO YRKK series wound rotor induction 6 pole ac motor, represented by the YRKK630-6GT model, is a robust high-power industrial drive designed for heavy-duty operations requiring exceptional starting torque and stable long-term performance. Produced by Xi'an Simo Motor Co., Ltd., a trusted global motor manufacturer, this series integrates advanced engineering to meet the demands of mining, metallurgy, power generation, and cement industries.

With a rated output of 1600 kW and a speed of 995 r/min at 50 Hz, the YRKK630-6GT operates under S1 continuous duty. Its high-voltage stator (10000 V, 114.2 A, star connection) and wound rotor (1758 V, 542.4 A, star connection) deliver strong starting torque via external resistance, enabling smooth acceleration under heavy loads. A power factor of 0.85 ensures efficient energy use, while Class 155 thermal insulation and IP54 protection enhance reliability and safety.

Built for harsh environments, the YRKK series 6 pole ac motor uses an air-water cooling system, supporting operation at altitudes up to 2100 m and temperatures from -15 °C to 40 °C. The robust bearing system (NU238ECM drive end, 6336/C3 non-drive end) reduces vibration and extends service life, and the 10340 kg frame provides excellent mechanical stability. Compliance with OXD.511.007 standards guarantees adherence to global quality benchmarks.

Wound rotor induction motors are ideal for high-torque applications:

Mining: Crushers, ball mills, and bulk material conveyors.

Metallurgy: Rolling mills and process fans in steel production.

Power Generation: Boiler feed pumps and induced draft fans.

Cement: Kilns and large exhaust fans in cement plants.

The SIMO YRKK series 6 pole ac motor balances power, durability, and efficiency, offering a low-maintenance solution that maximizes productivity.
