YRKKYRKK / YRKK-W Series High-Voltage Wound-Rotor (Slip-Ring) Induction Motor
YRKK High Voltage Wound Rotor Motor HUALI
YRKK are totally enclosed high-voltage slip-ring motors: rotor resistance starting gives smooth acceleration with limited current and high torque for heavy inertia loads — mills, crushers, compressors, hoists. Voltage 6 kV (frames 355–1000) and 10 kV (450–1000), output 185–5600 kW, 4–12 poles, catalogue efficiency 93.2–96.2 %. Air-to-air cooling IC611 (IC616 with separate fan), IP44/IP54, class F insulation with class B rise, S1 duty, IMB3. Open version — YR series (IP23, IC01). Russian equivalents: AKZ, AKN. References: YRKK710-6-1800 (10 kV, Shenyang Bozhong), YRKK630-8-1000 at Chongqing Runjiang cement plant.
