Overcoming Stator End-Turn Mechanics & Lacing Tension Challenges
Why modern automated servo lacing is critical for industrial, mobility, and e-traction motors manufactured to European CE and VDE standards.
Dynamic Tension Stabilization
Manual or pneumatic lacing often leads to erratic tension spikes, causing hairline micro-fractures in enamelled insulation wire (IEC 60317). Our multi-axis servo lacing modules regulate continuous string feed tension within ±0.25 N, completely eliminating partial discharge triggers.
Geometric End-Turn Compaction
End turns must maintain strict clearance profiles to prevent phase-to-phase contact and housing interference. Our integrated machines combine 3D end-forming with diamond or chain lacing stitches, drastically shrinking radial coil overhang and maximizing heat dissipation into the lamination stack.
Vibration & Inverter Stress Endurance
High switching frequencies (PWM) from modern SiC inverters expose loose windings to extreme electrodynamic deflection forces. Precision double-sided synchronous lacing firmly consolidates slot phase boundaries, avoiding thermal degradation and short-circuit faults over 20,000+ operating hours.

| Slot Stator Clearance | Non-repeatable radial swell | Pre-formed & tightly anchored | Ensures clean motor frame housing assembly |
| Lacing Thread Compatibility | Polyester cord only | Nomex, Polyester, glass-fiber bands | Full compatibility with Class H / Class N insulation ratings |
Localized Applications in the Graz Automotive & High-Tech Corridor
Graz and the broader Steiermark (Styria) ecosystem represent one of Central Europe's densest advanced mobility hubs. Our stator lacing and production systems integrate seamlessly into high-mix, high-spec Austrian manufacturing workflows.
Tier-1 E-Mobility Sub-Assemblies
Graz is world-renowned for contract vehicle manufacturing and automotive R&D. Our automated machines configure stators for 48V mild hybrid generators, electric power steering (EPS) motors, and high-voltage e-axle traction units demanding stringent PPAP level documentation and IATF 16949 conformance.
Heavy Duty & Off-Highway Drivetrains
Austrian commercial vehicles, agricultural technology, and mountain transit machinery operate in severe shock environments. Our robust double-end stator lacing machines secure high-mass winding heads on heavy-duty traction motors, safeguarding windings against continuous low-frequency vibrations.
High-Efficiency Industrial Pumps & HVAC
Local industrial pump makers in southern Austria require stator lines targeting IE4 and IE5 Super Premium Efficiency standards. By optimizing coil wedge insertion and tight perimeter lacing, our machines reduce copper volume, minimizing ohmic stator resistance (I²R losses).
Trends Shaping Graz Motor Manufacturing: Hairpin, BLDC & Industry 4.0
The transition toward sustainable industrial production in Central Europe is imposing new operational challenges on motor winding, forming, and lacing hardware.
Migration to Hairpin & Continuous Wave Tech
As conventional random wire winding approaches its thermal and volumetric density limit, high-voltage vehicle programs across Austria are deploying hairpin stators. We design hybrid lines that bridge flexible needle winding with automated hairpin insertion, twisting, and CNC lacing for auxiliary EV drivetrains.
OPC-UA & Full Shop-Floor Digital Twins
Modern Austrian production facilities prioritize comprehensive data traceability. Nakro stator lacing machines incorporate Siemens or Beckhoff PLC systems supporting native OPC-UA protocols, logging every stitch tension, insertion force, and cycle speed directly into enterprise MES databases.
Rapid Quick-Change Tooling (SMED)
Shorter lifecycle times in industrial motor design necessitate flexible manufacturing. Our CNC lacing platforms feature quick-swap clamping chucks and multi-recipe touchscreen presets, cutting tool changeover for different stack heights or slot counts to less than 15 minutes.
