tating platform. The transmission between
the stator and rotor takes place via sliding
contacts and is extremely reliable.
Advantages: Application areas for Slip Rings:
• Rugged design for industrial use • Packaging machines
• Modular system construction • Printing machines
• Two-cavity system for load- and signal trans- • Textile machines (spinning machines)
mission • Special purpose machines
• Available in open or encapsulated design • Robots and handling equipment
• Protection rating for encapsulated model • Machine tools ( jig grinding machines)
IP 50 to IP 64 • Lifting platforms
• Long service life • Cranes
• Individually replaceable brush rings • Cable reels
• Replaceable rotors • Pipeline inspection systems
• Load and signal channels can be combined (down hole equipment)
selectively • Video surveillance (CCTV) equipment
• Variable overall length depending on the • Medical technology (Magnetic resonance
