YZYZ Series Squirrel Cage Three-Phase Asynchronous Motors for Crane and Metallurgical Use
Squirrel Cage Crane Motor XINDALI YZ
YZ is the squirrel cage version of Xindali's crane and metallurgical motors, built on the same platform as YZR: 1.5–30 kW at S3 40%, frames H112–250, 6 poles (1.5–11 kW) and 8 poles (7.5–30 kW), 380 V 50 Hz. The rotor has no slip rings or brushes, which simplifies maintenance; locked-rotor and breakdown torque are 2.0–2.5 × rated. Versions: IP44 with class F insulation for cranes and IP54 with class H insulation for metallurgical shops up to +60 °C. The version with a built-in disc brake is YZE (static torque 15–400 N·m for travel, 30–800 N·m for hoisting).
