Manufacturing Dynamo-Electric Machines TRIZ Cases

Simultaneous heating and pressurization bond all electrical steel sheets at once, cutting repeated lamination steps and compressive stress.

Chucks hold and tension winding wires before cutting, keeping wire ends aligned for automated motor coil manufacturing with less hardware.

Radial pushers compact wire ends in ferromagnetic core seats before twisting, reducing springback and improving alignment for accurate welding.

Gripping winding wires under tension before cutting keeps coil ends orderly, enabling simpler and more reliable motor winding automation.

Variable pitch spacing aligns undulated stator coils by radial slot position, reducing insertion strain and insulation damage.

Integral sintering joins the cylindrical magnet and armoring ring without shrink-fitting, improving rotor productivity and torque transmission.

A guided and pressed winding approach pre-curves rectangular wire to raise copper fill factor and thermal contact without wire deformation.

Sliding expanders, claws, and pushers keep holding force uniform on irregular motor stators to extract copper reliably without support changes.

A rotating pick-up and arrangement unit places hairpins in radial rows on concentric paths for faster, lower-cost stator core insertion.

Bladeless winding mat forming uses movable receiving and shaping tools to cut conductor stress while allowing variable pitch, length, and shape.

Partial stripping on three sides of stator flat wire ends enables laser joining with low axial height while protecting insulation and creepage distance.

Concentric bushings and a rotating carousel align and insert winding wires automatically, improving speed and precision while reducing wire stress.

Replace defective preformed coils inside a wind turbine generator using local wedge renewal and resin filling to preserve insulation and thermal conduction.

A CNC robotic platform refurbishes commutators in place, cutting disassembly, contamination exposure, and manual inconsistency.

Caulked plastic deformation locks the motor housing to the bracket, reducing EPS noise, vibration, defects, and extra fasteners.

A folded wave winding layout equalizes adjacent stator wire voltages, reducing partial discharge risk without thicker insulation or complex welding.

An overmolded sealing and cooling element isolates the stator from aggressive process gases while preserving cooling and machine life.

Offset first and second wave winding mats create single-layer start and end regions, enabling odd winding layers without added weight or space.

Movable impregnation and heating modules keep motor components stationary, reducing handling shocks while improving resin impregnation quality.

A grooved jig and radial pressing jig align segment coils into annular multi-layer assemblies without separate jigs, cutting size and cost.

A single bending member moves circumferentially and axially to form stator coil ends sequentially, cutting device size and interference.

Controlled winding and bending align stator coil ends without manual shaping, protecting insulation film and improving productivity.

Discrete protrusions on an annealing jig cut friction from thermal expansion mismatch, preserving iron core accuracy and oxide film uniformity.

Continuous gripping on a rotating index table removes re-gripping between bending stages, cutting hairpin conductor takt time.

Staggered completion timing for opposite-direction coil end bending avoids strong contact and protects stator segment insulation.
