Shenzhen HengDrive Technologies Co., Ltd. is one of the most reliable manufacturers and suppliers of bldc controller in China. With abundant experience, we warmly welcome you to wholesale bulk bldc controller made in China here from our factory. We also accept customized orders.
Bldc controller
Our company specializes in the design, development, and high-volume manufacturing of advanced Brushless DC (BLDC) controllers, serving industries ranging from electric vehicles and drones to industrial automation, medical devices, and home appliances. With over a decade of focused engineering experience, we have perfected the production of high-efficiency, low-noise, and highly reliable BLDC controllers that meet the rigorous demands of modern motion control.
Bldc controller Manufacturing Process & Technical Excellence
Every BLDC controller we produce goes through a tightly controlled manufacturing workflow:
SMT Assembly & PCBA Manufacturing:
Our fully automated SMT lines use high-precision placement machines (including Yamaha and Panasonic models) to mount components on PCBs with ±0.02mm accuracy. We use only 105°C-rated capacitors, automotive-grade MOSFETs, and high-Tg PCBs to ensure thermal stability and longevity.
Firmware Programming & Calibration:
Each controller is pre-programmed with customizable firmware supporting sensorless/sensored FOC (Field-Oriented Control), trapezoidal or sinusoidal commutation, and CAN/UART/PWM communication. We calibrate current sensing and phase advance parameters at multiple temperature points to guarantee consistent performance from -40°C to +125°C.
Conformal Coating & Potting (Optional):
For harsh environments, we apply acrylic or polyurethane conformal coating (IPC-CC-830 compliant) or full resin potting, achieving IP67/IP68 protection against dust, moisture, and vibration.
100% Functional Testing:
Every unit undergoes automated testing including: phase current balancing, over-voltage/under-voltage lockout, over-temperature cutoff, hall sensor signal integrity, and regenerative braking response. Test data is stored traceable by serial number.
Factory Advantages & Core Competencies
High Production Capacity:
With 8 SMT lines, 12 automated test benches, and a 10,000 m² ISO 7 (Class 10,000) cleanroom for assembly, we output over 500,000 BLDC controllers monthly while maintaining < 0.3% field return rate.
R&D Integration:
Our 35+ in-house engineers provide turnkey support – from schematic design and PCB layout (Altium/Cadence) to firmware optimization. We offer custom current ratings (5A – 300A), voltage ranges (12V – 96V), and form factors (down to 35×25×10mm).
Agile Supply Chain:
Strategic partnerships with Infineon, STMicroelectronics, and Toshiba ensure stable supply of critical components, with 6–8 week lead times for custom designs and 3–5 days for standard models.
Cost Efficiency:
In-house mold making, PCB fabrication (sister facility), and automated testing reduce intermediate costs, enabling us to offer prices 15–25% lower than European equivalents without sacrificing quality.
Certifications & Quality Compliance
Our commitment to safety and global standards is validated by the following certifications:
- ISO 9001:2015 (Quality Management System) – covering design, manufacturing, and after-sales service.
- IATF 16949:2016 (Automotive-grade) – mandatory for our BLDC controllers used in electric water pumps, cooling fans, and EPS systems.
- ISO 13849 (Functional Safety) – for controllers integrated into machinery requiring PLr d or e levels.
- CE & UKCA (EMC Directive 2014/30/EU) – passed radiated/conducted emissions and immunity tests per EN 55011 and EN 61000-4 series.
- RoHS & REACH – full compliance with lead, mercury, and phthalate restrictions, with material declarations available upon request.
- UL 508C (pending for selected models) – for industrial control equipment destined for North American markets.
- IP67 / IP68 (third-party verified by SGS) – for potted controller variants.
Quality Assurance & Traceability
We implement a closed-loop quality system: raw materials are IQC-inspected; production lot samples undergo accelerated life testing (ALT) including 1000-hour 85°C/85%RH humidity bias test, -40°C to +125°C thermal shock (200 cycles), and 10g vibration sweep. Every controller's serial number encodes production date, firmware version, and test station ID, enabling complete recall or analysis within 24 hours.
Customization & OEM/ODM Support
We offer full OEM/ODM services: from modifying current sense gain, adding Bluetooth/CAN gateway, or redesigning the power stage for ultra-low inductance motors. Our minimum order quantity (MOQ) for custom designs is only 500 units, with engineering samples ready in 15 working days.
Choosing us means partnering with an ISO/IATF-certified manufacturer that combines advanced automation, component-level reliability, and post-sales technical support. Whether you need a standard 24V/20A six-step controller or a fully customized 96V/200A FOC unit for an electric forklift, our production system delivers consistency, safety, and performance.
