Rotary Current Collector TRIZ Cases
- Dual-Face Brush Assembly for Wind Turbine Lightning Current Transfer
A dual-face brush assembly transfers lightning current between rotating and stationary wind turbine structures.
- Slip-Ring Unit With Radially Offset Brush Elements
Radially offset brush elements in a slip-ring unit transmit analog currents and high-frequency digital signals while minimizing electromagnetic interference.
- Segmented Brush Power Feeding Apparatus Wear Compensation
Alternating tapered brush pieces biased by coil springs maintain surface contact between concentric axis and cylinder bodies for reliable electrical conduction.
- Brush Dorsal Portion Design for Arc Reduction
A brush dorsal portion wider than the blade minimizes electric arcs during commutator contact.
- Dielectric Partition Arc Prevention Between Conductive Elements
A dielectric separating partition forces electric arcs into unstable paths, preventing short-circuits caused by ionization or dust in uninsulated spaces.
- Starter-Generator Brush Lead Butterfly Routing
Butterfly routing spreads brush leads to prevent rubbing against the brush box and inhibit carbon block movement.
- Alternator Slip Ring Labyrinth Seal and Positioning
A conductive ring assembly uses a partition ring and annular wall to form a protective labyrinth structure for the slip ring device.
- Cylindrical Fan Blades for Noise Reduction and Heat Dissipation
Rotary cylinders generate radial airflow via the Magnus Effect to cool components without wing-shaped blade interference.
- DC Motor Brush Holder Shielding Cap for EMC
Conductive shielding cap covers DC motor brush holder to reduce electromagnetic interference, eliminating complex external filtering components.
- Cast CrMoV Steel Alloy for Turbine Components
A cast CrMoV low-alloy steel composition enables turbine component manufacturing with reduced material costs.
- Carbon Brush Using Mesocarbon Powder for Motor Efficiency and Life
Mesocarbon powder with controlled abrasion scrapes commutator carbon film, resolving the trade-off between motor efficiency and service life.
- Brush Holder Assembly with Metal Brush Box Gaps for Heat Dissipation
Metal brush box assemblies mount into resin holder grooves, creating non-contact gaps that improve heat radiation and reduce noise.
- Rotatable Electrical Conduction Structure for Obstruction-Free Plug Access
A rotatable electrical conduction structure uses arc contact terminals to maintain continuous conductivity while allowing plug orientation adjustment.
- Resilient Member for Brush Holder Assembly
An elastic conductive member isolates the brush from the holder to reduce deposit buildup while maintaining stable electrical resistance.
