Manufacturing Dynamo-Electric Machines TRIZ Cases

Self-aligning collars and extraction bolts detach a motor from a gearbox safely, cutting maintenance time and lifting equipment needs.

Separating outer-ring press-fit from rotor shaft insertion avoids opposing axial forces, reducing bearing damage and extending service life.

Preformed coupled coils are deformed, annealed, and resin-coated to simplify motor coil connections and improve mass-production efficiency.

Overlapping press molding on opposite coil sides balances load direction, reducing strain and improving recess groove accuracy.

Measured resin extrusion and preheating replace fixed tablets, cutting motor core filling waste while improving slot fill control and throughput.

Pressed adhesive tape captures ferrous particles that washing leaves on magnetic rotors, while rotating the rotor for complete surface cleaning.

Plug-in wave winding wires replace complex interlacing, enabling automated coil production with reliable connections and low wire stress.

Preplaced insulation material melts over winding bond points, combining joining and insulation to prevent shorts with fewer process steps.

A two-pass laser scan uses high then lower energy to deepen pin-pair welds while reducing spatter, voids, and conductivity loss.

Direct hydraulic cooling in separated stator chambers boosts power density while a connecting element routes conductors and simplifies assembly.

A shaped strand joined to two flat wires improves winding insertion, fill factor, strength, and conductivity in electric machines.

A translatable collection drum fine-tunes conductive element alignment, cutting stator winding cycle time without robot complexity.

Projection-shaped rectangular wire tips are laser welded near the butting surfaces to remove trimming, cut waste, and shorten stator production.

Closed-loop laser paths form and connect molten pools to bridge stator conductor end gaps for faster, more reliable winding welds.

Radial nozzle motion turns arc-like winding into linear pole-relative travel, keeping wire rod tension stable and improving alignment.

Region-specific conductor layers and short-pitch winding reduce internal voltage drop, harmonics, torque ripple, and insulation stress.

An adjustable encoder in a recessed endshield channel cuts tolerance stack-up and simplifies precise motor sensor alignment.

Mixed halogenated monomers form a workable pre-ceramic polymer, enabling tailored SP1, SP2, and SP3 ceramic properties after thermolysis.
