Two Carbon Fibre Axes with Linear Motor (8 axes)

Demands

• Compact gantry shape for the fastest pick & place sequences
• ISO 5 cleanroom compatibility for particle-sensitive production
• 3-shift, 7-day duty without positional drift
• Redundant drive design for safe fault tolerance
• Quick swap of energy chains and cables to minimise downtime

Implementation

• Inherently rigid double linear-motor axis built from carbon-fibre beams
• Linear magnetic measuring systems with 1 µm feedback
• Intermediate service levels allow tool-less chain replacement
• Cable chains sized with spare capacity for future tooling lines
• Integrated collision protection on every payload axis
• Direct-drive linear motors provide high dynamics for sub-second moves
