High-speed Flender electric motors series KF equipped with a standard cylindrical shaft and keyway connection, they are used to perform manufacturing operations for machining various types of raw materials (wood, metal, glass and synthetic materials). Stable operation with a high degree of dynamics and accuracy.
Depending on the performance requirements, there are 6 standard size options to choose from, which in turn include several different dimensional variations. All electric motors are characterized by compact design, bearing assemblies are protected from dust and moisture penetration, surface cooling due to self-ventilation, adjustable electrical interface, continuous operation and intermittent mode without load with an increase in power by about 20% of the nominal values.
This series is available with single- and double-bearing bearings, with various types of terminal blocks, with and without a brake system, and many additional options are available for protection, reinforcement and monitoring.
