Windings Insulation Material TRIZ Cases

A dual-catalyst cycloaliphatic epoxy approach improves impregnation and curing while preserving storage stability and reducing insulation cavities.

Using ePTFE insulation, this case shows how magnet wire resists hydrolysis in high-pressure, high-temperature motors without extra barrier layers.

A ductile third sheath layer stops encapsulation cracks in motor windings, preserving insulation at high rotation speeds and high slot fill.

An epoxy resin with matched thermal expansion and high-temperature stiffness helps coils resist separation, stress, and rotor loads.

Intermediate elements between stator tooth groups add axial heat paths, cut weight, and support fluid or heat-pipe cooling in rotary machines.

A TiO2-silica filled polyimide multilayer insulation helps magnet wire withstand high voltage and frequency stress without thicker windings.

A three-layer enamel with silica and chromium oxide improves magnet wire corona resistance and thermal life while avoiding bend cracks.

An insulated hybrid stator core combines laminations and SMC portions to enable complex axial flux shapes while cutting eddy current and hysteresis losses.

A dual-layer insulation film uses metal oxide hydrate to form an inorganic layer under partial discharge, extending insulation life at lower cost.

Thicker insulation at stator conductor corners prevents voltage breakdown while avoiding bridging, excess potting material, and added cost.

A spacer and spring keep the varnish nozzle at a consistent gap on uneven stator surfaces, improving coverage and reducing varnish use.

Angled symmetric coil guide grooves let one stator insulator handle different coil diameters, improving winding regularity and coil space factor.

Foam-layer insulating paper creates uniform gaps between self-fusing winding wires, enabling direct coolant flow without varnish impregnation.

A non-combustible layer around coil ends blocks fire and smoke leakage in resin-molded motors when layer shorts occur.

Internal rotor fan blades, ventilation channels, and conductive heat paths cool enclosed electric machines without external fans.

Multi-layer slot molding combines dielectric insulation, thermal conduction, and electrostatic shielding to cut heat and support higher-voltage motors.

A coil covering member contains outgassing while preserving insulation between adjacent armature coils in vacuum equipment.

Nanoparticle-loaded insulation tape plus vacuum impregnation suppresses electric tree growth and extends high-voltage motor winding life.
