Bearings TRIZ Cases
- Magnetic Levitation Stator Structure for Precise Axial Rotor Positioning
Independent stator protrusions and coils generate upward and downward axial forces for flexible, accurate rotor position adjustment.
- Magnetic Bearing Power Converter Layout for Uniform Heat Dissipation
Alternating power devices across two converter lines spread magnetic bearing heat more evenly, cutting cooler size and control chip bulk.
- Ultrasonic Waxing of Bicycle Chains Without Pre-Cleaning
Ultrasound drives wax into chain-link gaps and breaks down oil or grease, enabling uniform bicycle chain lubrication without pre-cleaning.
- Magnetic Bearing Circuit Ring Grooves for Uniform End-Field Flux
Axial grooves in soft magnetic rings smooth end-surface flux in a magnetic bearing, cutting magnetic friction, heat, and rotation loss.
- Magnetic Bearing Power Converter Layout for Heat Dispersion
Alternating two magnetic bearing power converters across parallel lines spreads surplus heat, reducing cooler size and device encumbrance.
- Magnetic Bearing Redundant Control Branch Switching
A duplicated control branch with automatic failover keeps a magnetic bearing servo shaft under control when one control node fails.
- Air-Bearing Probe Storage for Thermal-Stable Profilometer Accuracy
Continuous air supply during probe storage preserves adiabatic cooling, limits thermal expansion, and keeps profilometer measurements accurate.
