Direct factory supply of high-voltage motor controllers, custom CNC enclosures, heavy-duty AGV brushless drives, and marine-grade lithium power systems tailored for Seoul OEMs.
As Seoul advances its zero-emission commercial vehicle policies and automated warehouse infrastructure across Gyeonggi-do, the demand for compact, high-efficiency, liquid-cooled high-voltage motor control units (MCUs) has intensified. As China's premier high-voltage controller manufacturer, our engineering team delivers industrial-grade drive solutions that balance raw power density with thermal durability.
By transitioning from traditional Silicon IGBTs to Wide-Bandgap Silicon Carbide (SiC) power modules, our controllers operate at operational DC bus voltages ranging from 300V to 800V. Switching losses are reduced by up to 65%, enabling higher switching frequencies (up to 20 kHz) without thermal choking. This provides Seoul EV platform integrators with 5–8% greater battery range per charge cycle.
Our controllers leverage dual 32-bit automotive-grade ARM Cortex microcontrollers running advanced Space Vector Pulse Width Modulation (SVPWM) algorithms. The system executes real-time Field-Oriented Control, decoupling direct-axis (d-axis) and quadrature-axis (q-axis) currents. The result is smooth, instantaneous torque delivery from zero speed with dynamic efficiency maximization across variable torque demands.
To maintain junction temperatures below 105°C during continuous heavy torque duty, our controllers feature embedded pin-fin liquid channels engineered into CNC-machined lightweight aluminum alloys. Designed to interface seamlessly with standard vehicle cooling loops, these modules prevent thermal throttling under high ambient urban heat and extended highway operation.

Seoul’s dense topography, stringent environmental legislation, and rapid adoption of automated smart infrastructure present unique engineering challenges. Our high-voltage controllers and integrated powertrain systems are active across key capital sector applications.
Last-mile commercial logistics between Incheon Port and Seoul require durable 400V/800V motor conversion kits. Utilizing our Electric Powertrain EV Conversion Kits for Commercial Vans, Korean fleet operators retrofit diesel platforms into quiet, zero-emission delivery vehicles compliant with the Seoul Green Transport Zone regulations.
High-density automated logistics hubs in Yongin and Hwaseong require exact micro-positioning and heavy torque delivery. Our High Torque 5000W - 10KW BLDC Servo Motors & Controllers provide dual-channel vector guidance, enabling seamless 24/7 robotic operations across automated assembly floors.
Seoul’s clean water corridor initiative requires non-polluting propulsion systems. Our integrated 36V/48V Marine Yacht LiFePO4 Battery Packs and Waterproof Controllers give passenger water ferries high continuous energy discharge, resistant to water ingress and saline corrosion.
South Korea's national K-EV strategy, coupled with Seoul's ambition to achieve carbon neutrality in municipal transportation, is accelerating the demand for reliable tier-1 component sourcing from specialized Chinese manufacturers.
With over a decade of dedicated research into motor control algorithms and high-voltage power conversion, our factory combines advanced SMT automated production with high-precision internal CNC fabrication.
We manufacture custom aluminum enclosures in-house using multi-axis CNC milling machines. Utilizing Colour Anodized Sandblasting Aluminum CNC Parts, we deliver IP69K-rated structural controller housings with optimal thermal contact surfaces and zero porosity.
Every high-voltage controller unit undergoes 100% automated optical inspection (AOI), full-load dyno thermal testing, dynamic high-voltage insulation tests, and Hardware-In-the-Loop (HIL) simulation to verify stability under harsh operational faults before dispatch.
Our dedicated international engineering desk offers direct CAD integration support, custom CAN bus matrix matching, and fast-track prototype sampling within 7 to 10 business days for Korean engineering teams.
Addressing common technical, logistical, and compliance inquiries from South Korean purchasing directors and chief engineers.
Our controllers are built with multi-stage internal EMI filtering networks and shielded CNC aluminum housings. We work closely with Korean system integrators to supply complete test reports (CISPR 25 Class 5) to streamline your local KC certification process smoothly.
Yes. We support customized CAN 2.0B, CAN-FD, SAE J1939, and standard MODBUS protocols. Our software engineers can pre-program custom DBC files and telemetry handshake commands tailored to your vehicle logic prior to delivery.
Standard prototype samples ship within 7 to 10 business days. Production batches ship via direct ocean freight to Incheon Port (approx. 24–48 hours transit) or express air freight to Incheon International Airport (ICN) within 24 hours.
Absolutely. Thanks to our full internal precision CNC turning and milling facilities, we can modify heat sink geometry, mounting tab dimensions, and liquid-cooling port orientations based on your 3D STEP files.
We support Korean innovation across all stages. The MOQ for prototype engineering units is 1 piece. For custom OEM mass production runs, MOQs start as low as 10 to 50 units depending on customization requirements.
Our dual microcontrollers monitor real-time NTC/PT100 thermal sensors embedded directly inside the SiC power module and motor stator windings. If temperatures approach maximum thresholds, the controller executes a smooth, dynamic current derating routine rather than an abrupt shutdown, preserving vehicle safety.
