This series of dedicated three-phase induction motors for compressors is designed considering the special working conditions of compressors. With center heights ranging from H80 to H355 mm and a power range of 0.55–355 kW, the insulation class is F. The temperature rise is rated according to Class B under standard conditions and Class F under service factor conditions. The motors feature service factors of SF = 1.15 and SF = 1.2, and adopt a special bearing configuration to ensure long-term normal operation of the bearings.

The lead wires can be custom configured according to customer requirements, protected with cable conduit sleeves and equipped with threaded connectors at both ends. This series of motors offers stable performance, making them suitable for long-term continuous operation of compressors and fully meeting the operational requirements of compressor applications.
