Actuator Systems for Telescopes

The Challenge

  • Use of rotative systems in telescopes for tracking/tracing stars/planets in their orbits
  • Extremely slow movement combined with fast reaction to interference factors at the same time (wind loads)
  • Very small cogging
Torquemotor vom Typ RMI 300-150 als Antriebsystem für Teleskope

The Solution by FGB

  • Torque motor of the type RMI 300-150
  • Speed: 1/day
  • Cogging 0,2 Nm
  • Low inductance and resistance to allow fast balancing of interference factors
