Windings Insulation Shape/Form/Construction TRIZ Cases
- Deformable Wire Guide for Electric Machine Coil Winding
A deformable wire guide conforms to conductors during winding to maintain precise tension and alignment.
- Electric Motor Winding-Free Space Reduces Capacitive Coupling
Stator slots with winding-free space and conductive shielding rings decouple high-frequency currents, reducing bearing wear in frequency converter motors.
- Rotary Electric Machine Bus Bar Cooling
An inner diameter bus bar occludes radial clearances between coil ends, directing refrigerant flow to improve cooling performance in rotary electric machines.
- Stator Protective Wall for Rotating Electric Machine Noise Reduction
A stator protective wall shields coil connection portions from cooling air flow to suppress pressure variations and reduce fan noise.
- Stator Winding Crank Shape Reduces Coil End Height
Segmented crank conductors lower coil end height to prevent overhanging while maintaining insulation reliability.
- Stator Insulator Yarn Securing Passage Design
Passage portions in the stator insulator guide securing yarn around lead wires, eliminating needle puncture risks that damage insulation integrity.
- Stator Guide Body Contours for DC Motor Winding Assembly
Segmented guide body contours ensure reliable electrical connections while minimizing installation space and preventing incorrect assembly.
- Electric Machine Active Part with V-Shaped Winding Overhang
Segmenting coils into independent parts and adjusting their inclination reduces unnecessary projection, lowering weight and resistive losses.
- Flexible Insulating Conductor for Rotating Electrical Machine Slot Packing
A conductor with a flexible insulating covering material allows wires to move relative to each other, enabling the bundle to deform and fill winding slots.
- Armature Asymmetric Gaps Heat Dissipation
Asymmetric gaps between tooth sections and edgewise coils facilitate heat transfer to the core, reducing thermal resistance caused by insulator thickness.
- Elastic Plug Sealing for Electric Motor Lead Wires
Injection pressure deforms tapered elastic plugs against partition walls, preventing sealant leakage through lead wire drawing portions.
- Segmented Motor Insulator Ribs Strength
Segmented insulator members with parallel ribs prevent deformation when thickness reduces for higher coil space factor.
- Stator Bus Bar Overlap Reduces Winding Complexity
Overlapping bus bar ends merge multiple wire connections into one operation, reducing winding complexity and motor size.
