Services
Carbon Brushes
Custom-engineered carbon brushes designed for industrial motors and generators. Our precision-manufactured brushes ensure optimal electrical conductivity and mechanical performance. Available in multiple grades including electrographite, silver graphite, and copper graphite compositions for specialized applications.
Brush Holders
Advanced brush holder systems featuring constant force spring technology. Our holders ensure consistent brush contact while reducing maintenance requirements. Available in adjustable, turbine-style, and traction-specific configurations for diverse industrial applications.
Shaft Grounding Systems
Proprietary BPK shaft grounding solutions that mitigate VFD-induced shaft voltages. Our systems use silver graphite brushes to redirect harmful currents, preventing bearing damage and extending motor lifespan in critical applications.
Carbon Graphite Components
Custom carbon graphite components for sliding electrical and mechanical applications. Our self-lubricating solutions perform reliably in extreme environments across aerospace, medical, and industrial sectors.
Spring Assemblies
Precision-engineered spring assemblies designed for consistent pressure maintenance. Our constant force springs improve brush life and performance while reducing maintenance intervals in demanding industrial operations.
Questions
What are carbon motor brushes used for?
Carbon motor brushes conduct electrical current between stationary wires and rotating parts in motors, generators, and alternators while maintaining low friction and wear.
How do I identify my carbon brush grade?
Brush grades are stamped on the brush face and indicate material composition. Common grades include electrographite for high-voltage applications and silver graphite for low-resistance grounding systems.
Why choose Helwig's BPK shaft grounding system?
Helwig's BPK system uses proprietary silver graphite brushes that maintain shaft voltage below 1V peak-to-peak, offering 10+ years of maintenance-free operation in harsh environments.
What causes rapid carbon brush wear?
Low spring pressure accounts for 80% of rapid brush wear cases. Other factors include contaminated operating environments, improper brush grade selection, and misaligned brush holders.
Do you offer custom-engineered solutions?
Yes, our engineering team develops custom carbon brush systems with 48-hour prototyping available. We serve specialized applications in aerospace, electric vehicles, and renewable energy sectors.
