YZRYZR Series Wound Rotor Three-Phase Asynchronous Motors for Crane and Metallurgical Use
Wound Rotor Crane Motor XINDALI YZR
YZR is Xindali's wound rotor asynchronous motor for cranes and metallurgical equipment: 1.5–200 kW at the reference duty S3 40%, frames H112–400, 6, 8 and 10 poles (1000, 750, 600 rpm), 380 V 50 Hz. It is designed for frequent starting, braking and reversing under vibration and shock; breakdown torque is 2.3–2.8 × rated. Slip rings are plastic-moulded, brush holders use constant-pressure springs. The crane version is IP44 with class F insulation, the metallurgical version IP54 with class H insulation for ambient up to +60 °C. The same platform yields YZRE with a built-in brake and the marine YZR-H.
