Engineered for Yokohama's High-Spec Motor Manufacturing
Meeting the rigorous technical benchmarks of Japan's automotive tier-suppliers, precision robotics developers, and commercial HVAC motor fabricators across Kanagawa Prefecture.
Automotive Tier-1 & EV Auxiliaries
Yokohama serves as a core engineering node for mobility innovation. Our automatic coil and wedge inserting machines support complex multi-pole winding layouts for electric power steering (EPS), coolant pumps, and HVAC blower assemblies, achieving high slot-fill ratios (>78%) without strand nicking or dielectric degradation.
Precision Servos & Industrial Robotics
Robotics manufacturers in Kanagawa require minimal electromagnetic cogging and ultra-compact coil end-turns. The HF-BS20 double-side servo lacing machine and our intermediate-to-final forming presses compact stator overhangs within sub-millimeter clearances, enabling clean installation inside high-density robotic joint housings.
Pumps, Compressors & Maritime Power
Operating in proximity to the Port of Yokohama and Tokyo Bay, regional maritime electrical equipment requires heavy-duty motor windings resilient to saline humidity and thermal cycles. Our rotor turning systems ensure concentric air gaps that mitigate harmonic vibration, while hydraulic shaft presses maintain strict press-fit integrity.

Technological Evolution in Yokohama's Electric Motor Ecosystem
Navigating Japan's stringent energy efficiency benchmarks, labor transformation, and industrial automation modernization.
The IE4 / IE5 Efficiency Mandate
Under the Japanese Top Runner Program and Yokohama’s municipal climate action frameworks, commercial motors must transition toward IE4 and IE5 efficiency ratings. Achieving these thresholds requires higher slot fill percentages with uniform wire placement to minimize copper loss (I²R). Our inserting tools preserve wire insulation integrity at extreme packing densities.
Workforce Demographics & Lean Automation
With Japan’s experienced machining workforce retiring, Keihin factories face a tightening technician supply. Our automated inserting, forming, and lacing lines replace craft-dependent manual coil insertion with repeatable, recipe-driven touchscreens (supporting Japanese and English user interfaces), allowing single-operator oversight over multi-machine cells.
Component Standardization for Maintenance
Yokohama maintenance teams require immediate access to replacement parts. We configure control systems using Japanese and globally standardized architectures—including Mitsubishi Electric, Omron, Panasonic, Schneider, and SMC pneumatics—ensuring zero latency when sourcing local electrical spares or performing plant-wide MES integration.
Why Japanese Engineering Teams Source With Zunqi
Direct manufacturer based in Dongguan's advanced hardware corridor, providing transparent verification, high-tolerance tooling, and lifetime engineering support.
Custom Tooling to Sample
Every blade, former, and wedge pusher is engineered specifically to your stator core laminations or DXF/STEP drawings. We build dedicated tooling that prevents coil cross-overs and core distortion.
Full-Line Synchronization
From slot paper creasing to final coil expansion, lacing, rotor turning, and shaft pressing, we deliver matched machines with synchronized cycle rates to prevent inter-station bottlenecks.
Pre-Shipment Trial Verification
Before packing, we test your machinery using your physical stator cores and wire samples. Customers receive complete high-definition FAT (Factory Acceptance Test) video runs confirming precision.
Export-Grade Industrial Packaging
Machines are secured to bolt-down steel skids, wrapped with VCI vapor corrosion-inhibitor film, desiccant treated, and crated in fumigation-free plywood ready for sea freight to the Port of Yokohama.
