Stuttgart represents the engineering heart of European mobility and precision machinery. Our stator manufacturing lines and armature cells are engineered specifically to comply with German automotive and industrial tier specifications.
For manufacturers across the Neckar valley and throughout Baden-Württemberg, transitioning from internal combustion platforms to electric traction architectures demands extraordinary reliability, high copper fill factors, and traceability down to the individual serial number. Our automated stator production lines are engineered to integrate seamlessly into this rigorous industrial landscape.
Automated needle winding, hairpin inserting, and trickle resin impregnation designed to feed powertrain sub-tier facilities across Sindelfingen, Zuffenhausen, and Untertürkheim. Ideal for auxiliary EPS drives, HVAC compressors, and 800V e-axle traction stators.
Baden-Württemberg is world-renowned for CNC centers and precision robotics. Our three-phase stator lacing and coil insertion machines build ultra-balanced, low-vibration induction and PMSM stators capable of exceeding 24,000 RPM continuous duty.
Dedicated assembly lines for automated guided vehicle (AGV) hub motors and industrial warehouse conveyor drives. Stations support outer-rotor winding, hall sensor integration, and end-of-line electrical diagnostic validation.
Strategic engineering shifts: Navigating high copper slot fill factors, DIN EN ISO 50001 energy audits, and Industry 4.0 data exchange across German manufacturing operations.
As German engineering groups accelerate their electrification targets, procurement officers in Stuttgart face stringent demands. Manufacturing lines cannot merely function as standalone equipment; they must communicate via standardized industrial protocols like OPC UA and Profinet, synchronize with plant-wide MES systems, and provide complete lot traceability down to the specific lamination stack batch.
Furthermore, energy conservation regulations have forced motor manufacturers to shift from standard IE2/IE3 induction motors toward IE4 and IE5 ultra-premium efficiency brackets, as well as brushless permanent magnet synchronous motors (PMSM). Meeting these targets requires higher slot fill rates—often exceeding 78% in traditional round-wire inserting and upwards of 85% in advanced hairpin configurations. Nakro Intelligent Equipment delivers tool designs with micro-polished insertion blades and precision servo-driven wire dispensers that prevent micro-scratches on enamel insulation, keeping partial discharge rates at zero even under high-voltage inverter switching pulses.
| Stator Technology Focus | German Industry Benchmark | Nakro Technical Specification | Quality & Operational Benefit |
|---|---|---|---|
| Coil Slot Filling Factor | > 75% for IE4 / IE5 Efficiency | Up to 82% (Round Wire) / > 86% (Continuous Flat Wire) | Reduced copper loss, compact thermal envelope |
| Control Architecture | Siemens S7-1500 / Profinet / OPC UA | Standardized Siemens / Beckhoff PLC Core Integration | Seamless integration with Stuttgart MES architectures |
| End-of-Line Testing (EOL) | VDE 0530 / DIN EN 60034 Standards | Surge (5kV), Hipot (AC/DC), Insulation Resistance & DCR | Immediate identification of inter-turn insulation weaknesses |
| Line Cycle Time (Taktzeit) | Sub-30 seconds per station | 18 – 28 seconds (Depending on slot & turn geometry) | Maximized hourly output for high-volume Tier-1 programs |
