Cooling/Ventillation Arrangement TRIZ Cases
- CO2-Oil Coolant Circulation System to Reduce Motor Stirring Resistance
See how a gas-liquid separator splits CO2 and oil into dedicated cooling and lubrication paths,
- High-speed hall-less three-phase vacuum cleaner motor
See how back-EMF detection replaces Hall sensors to achieve 80,000+ rpm in vacuum motors, reduc
- Single-Piece Motor Casing With Continuous Internal Cooling Channels
Integrated inspection caps preserve cooling channel continuity in a cast motor casing, improving sand removal, sealing, and heat exchange.
- Spiral Cooling Passage Layout for Uniform Motor Coolant Flow
Rectifying partition walls in widened spiral casing passages smooth coolant distribution, expand cooling range, and reduce pressure loss.
- Electric Drive Unit Fluid Path for Pump-Free Cooling and Lubrication
Housing baffles, a collar, seals, and conduits guide fluid to cool and lubricate bearings while reducing pressure without an auxiliary pump.
- Cooling Jacket Gap Bridging for Quieter Electric Machines
A swellable gap-filling material bridges the cooling jacket and housing during operation to cut vibration and sound without heavier walls.
- Truss-Supported Multilayer Insulation for Cryogenic Motor Rotors
Lightweight truss-separated low-emissivity layers cut heat transfer to superconducting coils while withstanding centrifugal loads.
- Rotating Multilayer Insulation for Lightweight Superconducting Motors
Passive multilayer insulation cuts radiative heat transfer to superconducting coils while avoiding heavy cryogenic coolers and plumbing.
- Axial Flux Motor Stator Cooling With Hydraulic Chambers
Separate hydraulic chambers cool axial flux stator windings directly, improving power density, compactness, and assembly.
- Motor Cooling Seal Assembly for Rotor Cavity Isolation
An elastomeric seal with a compressed annular bead isolates stator coolant from the rotor cavity to prevent air-gap leakage and drag loss.
- Stator Winding Cooling Body That Avoids Parasitic Currents
A high-conductivity, electrically resistive cooling body removes winding heat without changing inductance or inducing parasitic currents.
