Technical Mechanics of Stator Coil & Wedge Insertion
In-depth look at our servo-driven mechanical architectures designed to mitigate enamel shearing, maintain slot liner integrity, and deliver high slot fill factors (>80%) in demanding production environments.
Simultaneous Dual-Action Motion Profile
Traditional pneumatic-driven insertion systems produce jerky mechanical shocks that frequently result in microscopic micro-cracks in Grade 2 polyester-imide magnet wire enamel. In contrast, our machines utilize an synchronized dual-servo drivetrain.
The insertion blade pushing mechanism and the wedge feeding pusher execute an algorithmically synchronized motion curve. The inserting fingers guide the pre-formed coils through the narrow stator slot openings while the wedge guides simultaneously advance the pre-creased, pre-cut insulation wedges (Nomex, DMD, or Mylar) right behind the wire bundles.
This closed-loop motion eliminates the risk of wire strays slipping beneath the slot insulation, completely preventing phase-to-ground insulation breakdown during subsequent surge and hipot dielectric verification tests.

Technological Transformation Across South Korean Motor Plants
Strategic macro trends shaping capital investments in stator manufacturing lines across Incheon and the broader capital area.
Push for Ultra-High Efficiency (IE4 / IE5)
Under the South Korean Ministry of Trade, Industry and Energy (MOTIE) energy framework, industrial motors must meet stringent efficiency quotas. This requires tighter stator slot packing ratios and precise wedge crowning to reduce electromagnetic stray losses.
Harmonic OptimizationEV & Urban Air Mobility Electrification
Tier-1 automotive component developers in Namdong are rapidly expanding beyond internal combustion sub-assemblies to produce integrated e-axles, electric brake boosters, high-speed oil pump motors, and electric scooter wheel hub systems.
K-EV Supply ChainSmart Factory Level 4/5 Integration
Korean manufacturing operations increasingly mandate digital traceability down to each stator serial number. Inserters must log insertion force curves, wedge cut lengths, and tool wear metrics directly to centralized corporate MES architectures.
Full TraceabilityTurnkey Cell Delivery & Fast Lead Times
To shorten product launch schedules, manufacturers demand bundled lines incorporating paper inserting, multi-spindle coil winding, simultaneous coil/wedge insertion, intermediate expanding, CNC lacing, and final forming from one reliable supplier.
