Windings Insulation Shape/Form/Construction TRIZ Cases

Pre-fabricated connector rings automate stator winding-to-lug joining with welded bus bars and insulating overlays to cut assembly cost and discharge risk.

Inductive coils and magnetic cores transfer power across a rotating motor joint without arcing, wear, wire limits, or motor interference.

Arc-shaped cooling grooves with controlled dimensions preserve coil surface strength while lowering coolant flow resistance.

A wedge pressed between preformed coil legs improves contact with stator teeth, lowering coil temperature and insulation fault risk.

Connection bridges link inner and outer slot conductors across wider spans, improving stator winding accuracy and assembly reliability.

Segmented insulation rings with spacer and retaining elements protect hairpin winding heads from vibration cracks and short circuits.

Pre-shaped overlapping insulators wrap each stator conductor to prevent contact, close gaps, and simplify accurate slot assembly.

Selective peeling on segment coil insulation protects bent rising portions while avoiding coil intersections that can trigger partial discharge.

A shortened busbar-to-cover terminal connection limits foreign matter entry while reducing twisting, bending, scrap, and plating cost.

A coated insulation layer inside hairpin holes replaces insulation paper, improving motor heat dissipation, productivity, and cost.

Coil insulation lugs prestress contact-pin seals at stator feedthroughs, improving electronics-compartment tightness and blocking moisture ingress.

A heat-shrink tube conforms to edgewise-bent flat wire to eliminate insulation gaps and lower partial discharge inception voltage.

Embedded conductive insulation in motor slots and winding heads detects partial discharge from converter overvoltage before insulation failure.
