carbon brush & metal brush slip ring difference
As a more than 15 years experienced customized slip ring manufacturer, Ingiant knows the slip ring technology history very well. Today we would like to introduce the 3 generations of slip ring technology to our valued customers.
1. First generation is carbon brush slip ring, the advantage and shortcoming is as below:
Carbon brush slip ring Advantage:
Cost effective
Fast line speed
Can make to very large size
Apply to large current situation
Maintenance in regular time
Carbon brush slip ring Shortcoming:
Only can transfer current, cannot transfer signal and data
High electric contact resistance
Big noise
Large volume
Ablation in large current, high temperature situation
2. Second generation is single brush(Monofilament) slip ring, it’s a single brush contact with a V-groove, Ingiant can make customized monofilament slip ring per customers requirements, the advantage and shortcoming is as below:
Monofilament slip ring Advantage:
Low noise
Free maintenance
Low torque
Good electrical performance
Signal transfer
Very compact size
Monofilament slip ring shortcoming:
Only can use in low speed situation, cannot work with high speed
Poor shock resistance
Cannot load with large current
Heat dissipation performance just so so
Working lifespan shorter than bundle metal brush slip ring
Cost higher than carbon brush and bundle metal brush, as it’s gold-gold electric contact, mostly for laboratory
Insulation and withstand voltage performance just so so
3. The third generation of technology is fiber bundle brush technology, Ingiant with mature experience on make 3 generation slip ring, the advantage and shortcoming is as below:
Fiber bundle brush slip ring Advantage:
Stable contact point electrical performance
Low torque
Multi point contact, long working lifespan
Silver or gold material for electric contact
Stable signal/data transfer
Low electric noise
Ingiant fiber bundle brush slip ring shortcoming:
Cost higher than carbon brush slip ring, lower than monofilament slip ring
Protection level only can make IP65, cannot make IP68 steep in water work
Size bigger than monofilament slip ring, but much smaller than carbon brush type
