Tooling engineered specifically for electrical motor builders, automotive tier-1 suppliers, and pump manufacturers operating across the Plzeň region and Central Bohemia.
The city of Plzeň, situated in Western Bohemia, commands a monumental legacy in European heavy industry, precision mechanical engineering, and modern electro-mobility development. Anchored historically by massive transport machinery, locomotive propulsion systems, and advanced power generation equipment, the region has rapidly modernized into an advanced hub for Tier-1 automotive drivetrains, submersible industrial pumping systems, and industrial robotics. In this highly demanding manufacturing environment, motor reliability directly dictates competitive leverage.
Achieving the operational life cycles demanded by Czech machinery end-users requires eliminating manual winding variations and slot insulation breaches during high-volume production. Our Automatic Servo System Stator Coil and Wedge Inserting Machines serve Plzeň facilities by synchronizing copper or aluminum coil bundle transfer with precise composite wedge insulation pushing in one single, high-efficiency mechanical stroke. By deploying dynamic servo feed controls, the mechanical stress exerted on enameled wire insulation during lamination slot entry is reduced to near-zero levels, completely eliminating micro-abrasions that lead to premature inter-turn short circuits.
Whether configuring lines for asynchronous IEC standard frame stators (sizes 63 through 180), heavy-torque railway auxiliary cooling motors, or specialized low-inertia brushless permanent magnet servo units, our equipment architecture bridges high-speed cycle times with exceptional slot fill capability exceeding 78%.
Engineering teams in Plzeň operate across distinct industrial market sectors, each imposing rigorous technical benchmarks on stator geometry, dielectric integrity, and physical endurance. Our automated inserting lines adapt directly into these native environments:
Plzeň is world-renowned for rail engineering. High-vibration environments demand stators with pristine coil geometries and reinforced Nomex/DMD slot wedges inserted under strict tensile monitoring to withstand sustained thermal shocks.
Hydraulic equipment plants require tight slot packaging for hermetically sealed compressors and chemical pump motors. Single-stroke inserting guarantees zero insulation micro-punctures, preventing chemical wash-out breakdowns.
Tier-1 Czech automotive component lines require automated, repeatable cycle times under 25 seconds per stator core, paired with full digital feedback compatible with ISO 9001 and IATF 16949 audit traceability standards.
Across Central Europe, the European Union's Ecodesign Regulation (EU 2019/1781) has mandated progressive adoption of minimum IE3 and IE4 efficiency classes for low-voltage induction motors, with market pressure rapidly steering Plzeň enterprises toward IE5 ultra-premium efficiency and permanent magnet synchronous motor (PMSM) technologies.
Building an IE5 motor requires an exceptionally dense copper-slot fill factor, narrower tooth openings, and thinner electrical steel laminations (down to 0.35mm and 0.27mm silicon steel grades). Attempting manual coil inserting into tight, high-fill slots under these circumstances causes extreme mechanical strain, scrap rates exceeding 6%, and insulation scuffing. Our automated inserting systems resolve these engineering bottlenecks through:
Precisely guided magazine push blades ensure copper wire bundles slide in parallel, eliminating crossover hotspots and partial discharge risks under high-frequency inverter drives.
Automatic feeding, cold-creasing, cutting, and positioning of slot wedges from roll stock ensures every wedge fits the slot top contour with micrometer-level symmetry.
Programmable insertion force limits prevent mechanical buckling of thin silicon steel lamination stacks, safeguarding the stator magnetic core structure against interlaminar shorting.
Pre-aligned modular changeover assemblies allow shift technicians to convert frame tooling from 2-pole to 4-pole or 6-pole stator configurations in less than 45 minutes.
Our comprehensive motor line automation philosophy eliminates downstream assembly friction. From slot paper lining through final dynamic rotor turning, each cell is engineered to mesh perfectly with adjoining systems:
Automated feeding, folding, and placing of class F/H slot insulation paper without surface scoring.
High-speed continuous winding of multiple wire strands with exact turn-count sensors up to 3000 RPM.
Single-stroke simultaneous transfer of coil groups and composite wedges directly into stator slots.
Solid radial and axial pre-forming of coil overhangs to clear inner bore clearance tolerances.
Tension-controlled continuous cord lacing across both end windings for absolute mechanical shock resistance.
Precision hydraulic calibration ensuring total dimensional compliance with motor end-shield housings.
Machining outer rotor core diameters to preserve micrometer-level concentricity and uniform air gaps.
Controlled tonnage press-fitting of low-carbon steel shafts into rotor core assemblies without distortion.

Operating from Qishi Town, Dongguan—within South China's most sophisticated precision automation corridor—Zunqi Intelligent Equipment Co., Ltd. combines 17 years of dedicated global export experience with direct factory pricing. We bridge Chinese scale manufacturing economics with the stringent quality, safety, and component standards demanded by Czech technical directors.
We do not deliver generic machines. Push blades, guides, forms, and fixtures are machined to your physical stator laminations and proven via video trial runs before dispatch.
Control panels are engineered with familiar brands your maintenance teams in Plzeň already maintain: Siemens, Mitsubishi, Schneider, Omron, Panasonic, and SMC pneumatics.
Our bilingual electrical and tooling engineers maintain a verified response time of under 9 hours, backed by full remote video diagnostics and rapid DHL/FedEx air freight of spare wear components.
Before manufacturing begins, our technical engineering desk reviews your 2D/3D CAD drawings (DWG/STEP), detailing slot inner/outer diameter, stack height, slot entrance gap, wire gauge, and turn specifications. Customers typically courier sample lamination stacks and copper wire to our facility. We perform physical test runs and send full high-definition video verification and sample stators back for electrical surge and hipot testing before crate sign-off.
Yes. All electrical systems dispatched to the European Union and Czech Republic are wired strictly for 3-Phase 400V 50Hz (or 230V 50Hz single phase for auxiliary units). Control circuits adhere to 24V DC safety bus protocols, outfitted with CE-marked safety relays, emergency-stop circuits, and enclosed Lexan safety interlocks.
Standard build times for tooling and machine assembly range from 30 to 45 business days. International sea freight to European ports (such as Hamburg, Rotterdam, or Koper) followed by bonded rail or flatbed truck transport to Plzeň takes approximately 28 to 35 days. We furnish complete commercial documentation, packing lists, CE Certificates of Conformity, Bill of Lading, and Certificate of Origin to streamline customs release.
Every machine is accompanied by a 1-year comprehensive factory warranty and a critical spare parts package (push pins, wedge blades, guide plates, proximity sensors). If your production line introduces new stator frame geometries in the future, we fabricate and ship newly tailored tooling fixtures without requiring machine replacement. Our engineers provide remote interactive parameter setup via video link, while on-site commissioning can be arranged for full turnkey lines.
