FLK Series for Three-Phase Induction Motors in Screw Compressors

Description
The FLK series three-phase motors are designed for screw compressors, with housings made of high-strength cast iron. The terminal box can be mounted on the top or side. Rated power ranges from 1.15 to 1.35. Temperature rise should be tested at 80K under rated load; the motor temperature should be 99K, and the bearing temperature should not exceed 95°C. To ensure long-term stable operation, the FLK series three-phase induction motors use special bearings. Additionally, since the motor’s cable is directly connected to the compressor’s electrical control panel, extension cables of custom lengths are available. The cables are equipped with protective tubing and sealing glands at both ends.
