Electric Machines TRIZ Cases
- Non-Oriented Electrical Steel Sheet With Uniform AlN Precipitation
Uniform AlN precipitate distribution through incubation and controlled annealing stabilizes magnetic flux density and reduces iron loss.
- R-Fe-B Sintered Magnet Grain Boundary Design for High Coercivity
Localized heavy rare earth diffusion into widened grain boundaries raises coercivity in R-Fe-B sintered magnets while reducing Dy, Tb, and Ho use.
- Coil Segment Forming with Pivoted Rotation for Layered Assembly
Pivoting one slot insertion portion while moving the holder clear lets coil segments overlap into layers with fewer lifting steps.
- Non-Oriented Electrical Steel Sheet for Low-Loss Punching Accuracy
Controlled composition, grain size, and annealing reduce mechanical anisotropy while preserving low iron loss in punched motor cores.
- Stator Coil Expander for Uniform Slot Insertion
Annular piece members expand a wound stator coil uniformly, enabling one-step slot insertion with stable posture and less manual effort.
- Ester-Based Lubricating Oil Composition for EV Cooling and Flash Point
Balances EV cooling, electrical insulation, and flash point by tuning ester-based base oil viscosity, specific heat, and density.
