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
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:
