Manufacturing Dynamo-Electric Machines TRIZ Cases
- Stator Plug-In Coil End Detection Using 3D Laser Profiling
3D laser profiling locates stator plug-in coil free ends before and after welding to improve alignment accuracy and weld seam quality.
- Motor Bearing Holder Assembly to Suppress Creep Noise
Pre-loading the second bearing with a holder and press-fit shaft suppresses vibration and creep noise in a piston pump motor.
- Stator Coil-End Holder Layout for Faster Conductor Joining
Rotatable positioning members align stator coil ends in rows, cutting manual joining time while maintaining assembly quality.
- Modular Deflector Cover for Convertible Motor Ventilation
A modular deflector cover switches rotating electric machines between self-ventilated and forced cooling while cutting installation cost.
- Rotor Magnet Position Sensing in Axial Magnetic Sensor Motors
Using the rotor's own magnets for axial magnetic sensing removes separate position magnets, simplifying rotary machine structure and manufacture.
- Inductive Winding End Alignment With Radial Compaction
Radial alignment and compaction shorten winding free ends for welding, reducing space occupation while improving clamping strength and fault resistance.
- Axial Flux Machine Assembly for Clean, Precise Installation
Magnetically stacked rotor and stator parts simplify axial flux machine transport and create the operating air gap during installation.
- Hook-Shaped Stator Coil Joints for Jig-Free Laser Welding
Meshed hook-shaped coil ends enable low-power laser welding without precise jigs, reducing insulation rework and improving stator assembly reliability.
- Hairpin Terminal Alignment for Precise Stator Winding Assembly
A programmable pusher aligns and bends hairpin terminals in a slotted core to improve winding coupling precision without slowing production.
- Connection Ring Lug Geometry for Gap-Free Stator Conductor Welding
A widened fitting portion and narrower clamping portion spread stator conductors for gap-free contact and more reliable welding.
- Stator Coil Layout for Radial Access to Intermediate Protrusions
Shorter outermost and innermost coil protrusions open radial access to intermediate stator connections, easing busbar joining and laser work.
- Wire Winding Nozzle With Adjustable Rod for Bulge Control
A movable rod beside the winding nozzle adjusts wire reformation to suppress lift and bulging on rectangular magnetic poles.
