Windings TRIZ Cases
- Armature Winding for Rotary Electric Machine Magnetic Balance
Asymmetric armature winding pairs coils with opposite polarity to improve magnetic balance, reducing whirling and torque ripple.
- Generator Stator End Winding Coil Support Assembly
Tensioned studs threaded into inner braces apply precise clamping force to generator stator end winding coils, eliminating manual glass banding labor.
- Electro-hydraulic Stator Wedge Installation Tool
Electro-hydraulic tool applies uniform axial force to drive wedges over filler layers, reducing installation time from 20 seconds to 7 seconds per wedge.
- Rotary Electric Machine Frame Grooves for Stator Rigidity
Axial grooves in the drum portion lower press-fitting loads and inhibit stator core deformation, resolving contradictions between strength and shape.
- Motor Bus Bar Terminal Scrap Reduction
Segmented neutral and phase terminals on a motor bus bar reduce sheet metal scrap by optimizing layout for efficient punching.
- Planar Motor Stator Layer Arrangement for Parasitic Capacitance Reduction
Grouping longitudinal and inclined stator layers reduces parasitic capacitance, enabling high-frequency drive current modulation with lower energy losses.
- Rotary Electric Machine Unit Axial Length Reduction
A rotary electric machine unit positions a terminal block outside a conductive member holder in the radial direction to shorten axial dimensions.
- High-Speed Generator Oil Cooling Air Gap Friction
Segmented oil and air cooling passages prevent oil entry into the rotor-stator gap, reducing windage friction at speeds above 12,000 rpm.
- Slotless Winding Manufacturing via Cylindrical Tube Support
A three-axis winding head creates cylindrical slotless windings on a removable tube.
- Integrated Bus Bar Terminal Block Assembly for Motor Connections
A terminal block assembly integrates bent bus bar bodies with connector and coil terminals to secure motor wire connections.
- Hall Effect Sensor Mounting Bracket for Motor
Supporting columns extend from winding slot teeth to position the sensor, increasing creepage distance against high voltage breakdown.
- Automated Connected Coil Assembly Mounting for Magnetic Resolvers
A connected coil assembly forming unit and coil mounting unit automate sequential winding and placement of single coils on electronic member projections.
- Modular Insulation Module for Linear Motor Iron Core
Integrated insulation module merges partition walls to secure coil positioning and prevent short circuits during assembly.
- Electric Motor Stator Terminal Radial Extension for Axial Size Reduction
Radial terminal extension sandwiches coils to reduce axial enclosure size without lowering motor output.
- Stator Assembly Torque Measurement Coupling
Direct fusion welding of stator teeth to the holder eliminates coupling parts, reducing manufacturing cost and improving torque measurement reliability.
