Electric Machines TRIZ Cases
- Stator Coil Insertion Layout to Prevent Springback Gaps
A coil presser and outer restrictor hold stator coil ends after slot insertion, preventing springback gaps and improving layout uniformity.
- Stator Coil Insertion Guides to Prevent Insulator Twisting
Sequential first and second guide members keep slot insulators open during stator coil insertion, preventing catching, twisting, and buckling.
- Axial Motor Stator Fastening Plate for Cooling and Core Positioning
A grooved fastening plate positions spaced magnetic cores without pressure plates, improving axial motor cooling, magnetic conduction, and torque.
- Electric Motor Venting Layout to Keep Respiratory Membranes Dry
A bus bar group is placed between the coolant jet and vent opening to keep the respiratory membrane air-permeable without enlarging the motor case.
- Laminated Stator Core Welding Layout to Suppress Yoke Iron Loss
By shifting fitted welds away from the yoke outer edge, this stator core structure cuts residual stress and suppresses iron loss.
- Electrical Steel Sheet Coating to Suppress Nitriding in Motor Cores
A nitriding-suppressing coating lets one electrical steel sheet deliver high rotor strength and low stator iron loss after stress-relief annealing.
- Rotary Electric Machine Housing With Integrated Stator Cooling
Integrated fluid chambers and channels cool stator surfaces and end windings, cutting motor temperature and cooling system complexity.
- Tangential Motor Rotor Core Layout for Lower Harmonic Noise
Magnetic isolation holes in a tangential motor rotor core smooth air-gap flux density, cutting harmonic noise while improving torque stability and efficiency.
- Flat Wire Motor Winding Layout for Three-Branch Current Balance
Equal-span, six-layer flat wire winding balances three parallel branches to cut AC loss, limit hot spots, and simplify motor production.
- Laminated Motor Core Separation for Dimensional Accuracy
Pressing the element laminate during orthogonal separation avoids excess magnetic attraction and improves laminated motor core accuracy.
- Rotating Electric Machine Case Flow Path for Uniform Stator Cooling
A variable-thickness case flow path offsets refrigerant heating downstream to keep stator cooling more uniform along the machine.
- Stator Coil Laser Welding Across Dual Stations With One Oscillator
A shared laser oscillator welds stator coil segments at two stations with timed irradiation, raising throughput while limiting heat and insulation damage.
- EV Lubricating Oil Composition for Cooling and Flash Point Balance
An ester-based EV lubricating oil balances low-viscosity cooling with electrical insulation and a high flash point through tuned base-oil properties.
- Sintered R-T-B Magnet Composition for High Coercivity and Br
Controlled Nd/Pr and Cu diffusion raises high-temperature coercivity while preserving Br and reducing Tb use in sintered R-T-B magnets.
- Axial motor, powertrain, and electric device
A grooved stator fastening structure positions magnetic cores on step surfaces while improving axial motor heat dissipation and torque.
