Leveraging its world-class gear inspection center, PREETO employs high-precision equipment including ZEISS Industrial CT (3D micron-level defect scanning), Klingelnberg gear inspection centers, ZEISS coordinate measuring machines (accuracy ≤1.5μm), gear meshing testers (dynamic transmission performance validation), and thermogravimetric analyzers. This enables a closed-loop inspection system covering material composition, structural defects, geometric precision, and dynamic meshing performance. The lab achieves nano-level precision verification of all parameters for individual gears, providing a robust technical edge that surpasses industry standards for gear development.
PREETO operates a dedicated reliability laboratory specifically designed drive motors for e-bikes, adhering to rigorous testing protocols. Utilizing equipment such as multi-functional vibration testers (simulating off-road bumps under various temperature settings), temperature and humidity chambers (-40°C extreme cold to120°C extreme heat validation), thermal shock chambers (testing structural tolerance to sudden temperature changes), IPX7-rated rain test chamber simulating torrential downpours), salt spray testers, and noise analysis systems (ambient lab noise <25 dB), PREETO conducts comprehensive accelerating tests under extreme multi-dimensional environmental conditions. This ensures the motor maintains exceptional reliability in core performance areas like torque output during hill climbs, protection against mud and water ingress, cold start capability ability for low temperature, and vibration/noise control, providing all-weather reliable cycling power.
The EMC lab features a high-precision semi-anechoic chamber capable ofaccurately simulating complex electromagnetic environments for stringent testing of mid-drive motor's radiation immunity. A professional-grade shielded chamber.paired with advanced conducted emissions and immunity testing equipment,meticulously detects conducted interference during motor operation, ensuringstable, noise-free power sianal transmission, With this cutting-edge equipment and comprehensive testing system, PREETO continuously breaks through technical bottlenecks in mid-drive motor development, consistently launching innovative products with outstanding performance and superior electromagnetic compatibility.
PREETO leverages its extensive product development experience from the automotive, medical, and embodied intelligence industries into the e-bike sector, delivering solutions built to higher standards.
Considering the real-world application scenarios of e-bike mid-drive motors and optimizing for multiple objectives like transmission efficiency, noise control, and spatial integration, PREETO utilizes its fundamental database and proprietary software to generate multiple feasible design solutions. These undergo multi-round optimization to achieve the optimal design.
Through proprietary tooth profile optimization software, PREETO comprehensively considers factors including load distribution, transmission efficiency, and wear life to effectively reduce meshing noise and enhance transmission smoothness.
Employing professional simulation software, PREETO conducts comprehensive analysis of components, motors, and gearboxes, covering molding processes, electromagnetic performance, strength verification, mechanical properties, thermal behavior, and vibration characteristics. This enables the prediction of potential issues early in the design phase, providing a scientific basis for iterative improvements and ensuring the gearboxes possess outstanding performance and reliability.
