Technical Overview: Automated Stator Manufacturing & Processing Lines
In modern electric motor manufacturing, automated stator processing equipment determines slot fill factors, insulation reliability, and coil geometric consistency. Automated systems built by SMT Intelligent Device Manufacturing (Zhejiang) Co., Ltd. under the brand SMT integrate paper insertion, coil winding, wire inserting, intermediate forming, and slot expanding operations into structured production workflows.
Evaluating automated motor machinery requires analyzing mechanical tooling structure, hydraulic force application, motion control integration, and shop-floor safety protection. This technical documentation reviews core equipment configurations, component specs, operational process steps, and engineering selection parameters for stator coil processing machinery.

Engineering Analysis of Technical Components
  • Model SMT-KCG300 Slot Cover Machine: Utilizes specialized metal tooling dies and roller guidance mechanisms designed for stator slot cover expanding. Dual external button control stations enable symmetrical operational inputs while maintaining structural alignment during high-cycle expansion tasks.
  • DELTA HMI Touch Screen Interface: Provides programmable recipe storage, real-time pressure monitoring, and operational cycle diagnostics. Direct digital parameter adjustments minimize dynamic setup errors when shifting between different motor stack heights.
  • KUNDE Safety Light Curtain Infrastructure: Integrated vertical safety columns monitor operator insertion zones, triggering immediate circuit interruption during physical obstruction to maintain shop-floor safety compliance during automatic forming sequences.
  • Sequential Process Workflow in Stator Assembly
    Achieving uniform wire distribution and preventing phase-to-phase insulation damage requires sequential alignment across four primary manufacturing stages:
    Stage 1: Slot Insulation & Paper Cutting
    Insulation paper is indexed, cut, shaped, and inserted into stator core slots. Precise edge folding prevents mechanical tearing during subsequent copper wire coil insertion.
    Stage 2: Coil Winding & Insertion
    Enamelled copper wire coils are pushed simultaneously with slot wedges into stator core slots using precision spline shafts and inclined guides, preserving wire coating integrity.
    Stage 3: Intermediate Hydraulic Forming
    A vertical hydraulic cylinder drives internal expanding dies and external forming rings. This reshapes end-turn coil overhang dimensions to clear subsequent lacing and housing clearance limits.
    Stage 4: Slot Cover Expansion
    Operating via model SMT-KCG300, the slot cover expanding process locks insulation wedges, eliminates radial wire protrusion, and prepares the stator bore for rotor clearance checks.
    Engineer's Technical Evaluation & Inspection Criteria
    When conducting technical reviews of stator coil processing equipment, motor design engineers must assess parameters based on rigid mechanical tolerances and electrical safety boundaries:
  • Frame Rigidity & Alignment: Heavy-duty welded steel structures prevent frame deflection under hydraulic pressing forces, ensuring axial alignment between the upper forming cylinder and lower fixture dies.
  • Interface Programmability: The DELTA touch screen must support multi-formula storage, permitting quick switching of displacement timing and dwell times for distinct stator stack lengths.
  • Interlock & Safety Compliance: Dual push-button start interfaces combined with KUNDE optical safety curtains must instantly lock out pneumatic and hydraulic actuators whenever a safety perimeter breach occurs.
  • Insulation Integrity Verification: Post-forming inspection requires checking that phase insulation papers are untwisted and that enamel wire coatings exhibit zero scratch marks under high-potential dielectric testing.
