Magnetic Circuit TRIZ Cases
- Outer-Rotor String Trimmer Motor With Adhesive-Free Magnet Retention
A toothed magnet base and sealing heat sink simplify outer-rotor string trimmer motors while improving torque, cooling, and durability.
- Axial Flux Inboard Propulsion Layout for Lower Gyroscopic Steering Load
Paired axial flux motors on a perpendicular gearbox input cut gyroscopic steering load while preserving limp-home resilience in inboard vessels.
- Permanent Magnet Rotor Resin Fixing for Higher Holding Force
A segmented resin structure fixes rotor magnets by filling the core gap and partly covering magnet ends, easing manufacture without losing holding force.
- Planetary Outrunner Motor Assembly for Flexible Torque-Speed Output
Combining outrunner motors with a planetary gear train broadens torque-speed output while reducing custom motor development time and cost.
- Permanent Magnet Rotor Offset for Low-Cogging Torque Pulsation
Asymmetrically offset permanent magnets cut cogging and torque pulsation in EV traction motors while avoiding the efficiency loss of conventional fixes.
- Halbach Rotor Assembly with Yoke Magnetization for Easier Build
Pre-magnetized rotor magnets and yoke magnetization form a circular Halbach array with less drag-force interference and higher assembly productivity.
- Axial Flux Boat Propulsion With Stern or Jet Drive Integration
Combines axial flux motors with stern or jet drive layouts to raise electric boat power density while managing integration and cooling.
- Flux-Concentrating Rotor Core Cutout for Lower Leakage Flux
A lower-end core cutout bends flux flow to raise magnetic resistance, reducing leakage flux while preserving rotor rigidity and output.
- Modular Stator Cooling Assembly With Heat Pipes and Low Pressure Drop
A modular U-shaped pipe and heat-pipe layout cools linear motor stators with lower pressure drop, lower leakage risk, and strong thermal performance.
- Permanent Magnet Rotor Bridge Layout for Lower Flux Leakage
A staggered bridge layout in a permanent magnet rotor cuts flux leakage and torque loss while reducing bridge stress concentration.
- Linear Induction Wafer Transport Without Vacuum Bearings
A linear induction maglev handler moves wafers in vacuum without bearings, reducing outgassing, particles, friction variability, and arm deflection.
- Composite Rotor Sleeve With Ferromagnetic Pins for Magnet Retention
Ferromagnetic pins in a laminated composite rotor sleeve improve magnet retention, flux channeling, and heat transfer in high-speed electric machines.
- Rotor Magnet Support Mechanism for Accurate Outer-Surface Attachment
Inclined support members hold rotor magnets against strong magnetic forces, preserving posture and positioning during outer-surface attachment.
- Two-Layer Permanent Magnet Rotor With Interlocking Magnet Interface
Interlocking recesses and projections strengthen bonding between ferrite and rare-earth bonded magnets in a two-layer rotor.
- Axial-Flux Motor Heat Sink Plates for Winding Cooling
Concave metallic plates placed between windings and stator walls draw heat from hard-to-cool zones and improve electric motor cooling.
