Electromagnets Without Armatures TRIZ Cases
- Injection Controller Voltage Boosting for Low Voltage Operation
An injection controller applies boosted voltage to a driving coil when terminal voltage drops below a threshold.
- Magnetizing Small-Diameter Multi-Poled Ring Magnets
Heating small-diameter multi-poled ring magnets above their Curie point reduces current requirements and variation in surface magnetic flux density.
- Coil-Integrated Yoke Manufacturing for Precise Electron Beam Deflection
A coil-integrated yoke uses sequential groove insertion and surface polishing to secure components.
- Superconducting Flux Pump Using Temperature-Regulated Magnetic Circuit
A superconducting flux pump generates magnetic field waves to induce persistent currents within a superconductor.
- Electromagnetic Coil Tactile Feedback for VR Immersion
Electromagnetic coils replace mechanical actuators to resolve the contradiction between device complexity and user immersion in virtual reality.
- Actuator Core Demagnetization for Fuel Injector Reliability
Demagnetizing electromagnet cores reduces residual magnetism, lowering current requirements and preventing coil degradation in dual coil fuel injectors.
- Magnetic Fixing Device with Self-Indicating Resin Layer
Transparent resin layers change refraction rates near Alnico magnets, revealing adsorption states without external control panels.
- 2D Magnetic-Optic Trap Frequency Modulation for Atomic Beam Flux
Frequency modulation extends laser linewidths to increase atomic beam flux, resolving the trade-off between trapping efficiency and atom capture rate.
