Windings TRIZ Cases
- Slot-Less Armature Coil Module Fixing for Precise Positioning
Coil modules engage a base member circumferentially to secure slot-less armatures with accurate positioning and lower cogging torque.
- Waterproof Fan Resin Layout to Block Thermal-Stress Water Ingress
A positioning member keeps the circuit board off the frame wall so waterproofing resin can resist thermal-stress gaps and protect the fan electronics.
- Intersecting Bus Bar Terminal Assembly for Compact Hairpin Motors
Intersecting bus bars nested in an insulated body cut terminal space in hairpin motors while improving bus bar isolation and mounting safety.
- Redundant Brake Control Units for Fail-Operational Braking
A backup control unit mirrors the primary brake controller so valves and motor control continue during electronic failure, improving vehicle safety.
- Stator Interconnection Layout for Uniform Phase Resistance
Axially arranged interconnection traces equalize stator coil wire lengths across phases, improving resistance balance and machine efficiency.
- IPM Rotor Magnet Structure for Flux Direction and Pole Strength
Dual magnets and joint-side support improve pole-piece strength while directing flux outward to reduce leakage and magnet use.
- Coded Auxiliary Tooth Vernier PM Motor for Higher Torque Density
Coded auxiliary stator teeth superimpose magnetic fields to raise vernier PM motor torque density without adding more permanent magnets.
- Busbar Sensor Assembly for Coreless Motor Current Measurement
Two symmetric magnetic field sensors on a busbar measure motor current without a heavy metal core, cutting space, weight, and cost.
- Iron-Core Linear Motor Forcer With Integrated Aerostatic Guidance
Integrated air channels and magnetic preload create a frictionless air film, improving geometric accuracy while reducing bearing assembly complexity.
