Lenze g500-B Bevel Helical Right-Angle Geared Motors
The Lenze g500-B Series (featured model: g500-B450/m550-P90L4 1.5 kW IE3) is Lenze's flagship right-angle bevel helical geared motor platform, engineered for maximum mechanical efficiency, wear-free bevel gear operation, and high radial load capacities. Achieving gear transmission efficiency up to 96% across all reduction ratios, g500-B gearboxes feature lightweight aluminum housing construction (g500-B45, B110, B240, B450) and rigid cast iron housings (g500-B1500, B4500), covering output torques from 45 Nm to 4,500 Nm. Matched with modern **Lenze m550 IE3 Premium Efficiency Three-Phase Motors** (or Lenze Smart Motors), g500-B right-angle geared motors provide 100% direct 1-to-1 mechanical compatibility to replace legacy **Lenze GKS Series** gearmotors in roller conveyors, mixers, packaging systems, and material handling plants.
