Factory-direct coil processing equipment engineered by Zhejiang Rilvo Automation. Every system integrates multi-axis servo tension control, rigid mechanical cam linkages, and automated cycle sequencing built to match exact slot geometries.
Operating in close synergy with the Rhine Valley's world-leading precision engineering corridor, industrial equipment deployed into Balzers and the surrounding Principality of Liechtenstein must meet uncompromising European standards for dielectric insulation, dimensional repeatability, and thermal endurance.
Balzers is globally recognized for high-vacuum surface engineering, advanced thin-film coating apparatus, and precision deposition systems. The turbomolecular pumps, rotary motion feedthroughs, and vacuum chamber drives manufactured in this corridor require stator assemblies completely devoid of micro-vibrations and corona discharge.
Our stator coil lacing machines utilize programmable needle tensioning with specialized non-abrasive lacing filament (polyester, Nomex, or braided aramid). By firmly immobilizing coil end turns without piercing magnet wire enamel coatings, our equipment prevents end-turn displacement during extreme vacuum cycles and rapid magnetic field acceleration.
Regional equipment integrators serving Swiss and Liechtenstein mechanical engineering plants frequently develop custom servo actuators, collaborative robotics joints, and automated material handling spindles. These devices prioritize minimal stator overhang and high slot copper fill factors to maximize continuous torque density.
Our dual-end stator lacing and diamond-forming configurations standardize coil overhang geometry down to ±0.2 mm tolerances. Through servo-driven rotary indexing tables and synchronized dual-needle heads, both coil overhang ends are laced simultaneously with selectable stitch styles (single-slot lace, jump lace, or overlapping lock knots), enabling compact enclosure integration.
Tier-1 automotive component developers in the Alpine region design auxiliary electric pumps, steer-by-wire servos, and thermal management compressors. These brushless permanent magnet (BLDC) motors operate under rigorous automotive vibration profiles governed by stringent ISO and VDA specifications.
Rilvo automatic stator coil lacing systems ensure that individual slot windings cannot shift under 30G harmonic vibration environments. By integrating automated cord cutting, knot tension verification, and PLC-monitored thread rupture sensors, our machinery delivers the total auditability and zero-defect output demanded by automotive quality teams.
Manufacturing across Balzers, Schaan, and the St. Gallen Rhine Valley is actively adopting Industry 4.0 production standards. Stator coil fabrication is no longer treated as a manual secondary process, but as a closed-loop data-monitored manufacturing stage.
1. Transition from Manual Cord Tying to Multi-Axis CNC Lacing: Rising labor costs and the demand for zero-tolerance quality assurance make manual coil strapping obsolete in modern European plants. Automated lacing ensures identical knot tightness and eliminates human strain fatigue, reducing cycle times from minutes down to 8–18 seconds per stator.
2. Tight Integration of Inserting, Shaping, and Lacing: Rather than moving stators across unconnected workshops, Balzers engineering projects increasingly combine our DQ-1 / 5 DQ-1 Stator Wire Embedding Machines with 3-dimensional hydraulic coil shaping and automatic lacing stations in a continuous, conveyorized cellular workflow.
3. Enhanced Quality Tracing & Digital Interfaces: Modern production facilities demand industrial fieldbus connectivity (Ethernet/IP, PROFINET, or Modbus-TCP). Rilvo machines integrate Omron or Mitsubishi PLC architectures with intuitive multilingual touchscreen HMIs, allowing local technicians to save up to 100 unique stator recipes and export telemetry data for overall equipment effectiveness (OEE) tracking.
Established in 1998, Zhejiang Rilvo Automation Equipment Co., Ltd. operates an integrated 60,000 m² high-tech campus in the Shatianyang Development Zone of Sanmen, Taizhou, China. We eliminate trading middlemen by designing and manufacturing all precision tooling in-house.
Unlike assembly-only workshops, Rilvo hosts over 150 dedicated precision machining centers, CNC milling units, and grinding apparatus. Needle guides, lacing shuttles, stator index fixtures, and coil inserting blades are heat-treated and machined internally to sub-micron tolerances, ensuring extreme wear resistance.
Led by our President and Chief Engineer—honored with the National Knowledge-Worker Model Award from the All-China Federation of Trade Unions—our team holds 17 national invention and utility patents. We provide full OEM/ODM tooling customisation adapted directly to your proprietary stator lamination CAD drawings.
With an export share reaching roughly 30% of annual output across Europe, South America, and Asia, we ship smoothly under FOB, CFR, CIF, and EXW terms via Ningbo deep-water port (2 hours away). Every machine undergoes sample trial testing with customer parts prior to dispatch, backed by remote video commissioning and full spare-parts provisioning.
