Squirrel Cage Crane Motor .
YZ Series Squirrel Cage Three-Phase Asynchronous Motors for Crane and Metallurgical Use
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).
