R&D Strength
Kechen Motor has a strong and experienced R&D team with extensive backgrounds in motor design, gearbox development, and precision manufacturing. Our engineers bring years of hands-on industry experience, enabling them to efficiently solve complex engineering challenges and deliver reliable designs that meet real-world application requirements. The team is supported by multiple specialized laboratories equipped with advanced testing and analysis systems, including dynamometer test benches, gear measurement centers, and environmental chambers. These facilities support both rapid prototyping and thorough performance evaluation under simulated operating conditions.
Our engineers apply proven design methodologies such as FMEA (Failure Mode and Effects Analysis) to identify and address potential risks early in the development process, and VE (Value Engineering) to optimize designs for cost-effectiveness without compromising quality or performance. They also leverage advanced analysis tools, including high-precision motor performance test systems, starting torque testers, and professional gearbox design software, to ensure each component is precisely tailored for its intended application. This integrated approach helps accelerate development cycles while enhancing product robustness.
To ensure our motors and gearboxes meet the highest reliability standards, we conduct comprehensive validation tests across a wide range of operating conditions. These include cogging torque test to minimize start-up vibration, endurance test to verify long-term durability, NVH test to ensure acoustic comfort, thermal shock test to assess resistance to temperature extremes, salt spray test for corrosion resistance, vibration test to confirm structural integrity under mechanical stress, and EMC/EMI tests to meet international electromagnetic compatibility standards. Each test is performed in accordance with relevant ISO, IEC, or customer-specific requirements, with results carefully documented to support traceability and continuous improvement. By maintaining a tight feedback loop between design, testing, and refinement, we consistently deliver products that perform reliably in demanding applications such as automotive actuators, industrial automation, and home appliances.

Motor and Gearbox Development

Motor Design Highlights

Rotor with Subsidiary Groove Design
The motor runs smoothly due to a subsidiary groove design that greatly reduces cogging torque. This design is particularly suitable for applications requiring precise motion control, such as automotive actuators and industrial automation equipment.

High Power Density Design
Optimized stator/rotor diameter ratio and slot profile achieve 20% higher torque output per unit volume compared to conventional designs.

Minimized Axial End Play Design
The noise of gear transmission systems such as reduction gearboxes can be effectively suppressed with the application of minimized axial end play motor design (end play less than 0.10 mm).

Automated Winding Compatible Design
The rotor design is optimized for automated winding processes, ensuring precise coil placement, consistent wire tension, and high production efficiency for reliable mass production.
