One modular system – numerous possibilities for planetary servo gear units

  • P1.G.. – the ingenious introduction to servo drive technology
    Simple, compact, and cost-optimized, performance class P1.G.. is the efficient solution for standard applications with modest requirements in terms of precision and overhung loads. It is ideal for cost-effective automation solutions on a limited budget.
  • P2.G.. – the robust basis for increased requirements
    Performance class P2.G.. is the right choice for applications with slightly higher mechanical loads, without compromising on compactness, efficiency, or reliability. It offers a robust basis and reserve overhung load capacity.
  • P3.G.. – the cost-effective all-rounder for demanding applications
    Performance class P3.G.. combines cost-effective efficiency with a high level of technical performance. Using the high-quality main bearing arrangement of performance class P5 and the same mechanical interface, in conjunction with the cost-optimized design of performance classes P1 and P2, makes it ideal for applications with high overhung and dynamic loads.
