Lenze g500-H Coaxial Inline Helical Geared Motors
The Lenze g500-H Series (featured model: g500-H1000/m550-P90L4 1.5 kW IE3) is Lenze's state-of-the-art coaxial inline helical geared motor platform, engineered for maximum energy efficiency, high power density, and seamless integration with variable frequency drives. Achieving gear transmission efficiency up to 94% to 96%, g500-H gearboxes feature lightweight aluminum housing construction (g500-H450 and H600) and rigid cast iron housings (g500-H1000 and H1400), covering output torques from 45 Nm to 1,400 Nm. Matched with modern **Lenze m550 IE3 Premium Efficiency AC Motors** (or Lenze Smart Motors), g500-H geared motors provide 100% direct 1-to-1 mechanical compatibility to replace legacy **Lenze GST Series** gearmotors in roller tables, belt conveyors, pumps, and packaging machinery.
