Test

We develop and supply customized special-purpose test equipment, delivering solutions optimized for each customer’s specific objectives. At KNR Systems we strive to be a trusted partner in research and development, supporting innovation through tailored engineering and technical expertise.

Robot

KNR Systems provides hydraulic robotic arms, standard mobile robots (robot arm platforms), hydraulic components, and robotic solutions based on its unrivaled hydraulic robot technology.

Traction Motor

As a core component of electric vehicles, the traction motor plays a vital role in determining driving performance and energy efficiency. Therefore, accurate evaluation and optimization using dynamometers is essential. Through comprehensive testing, automotive manufacturers can measure and assess key parameters such as output power, torque, efficiency, and durability of the traction motor—ensuring high-quality development and reliable performance across various driving conditions. Among KNR Systems testing solutions, the electrically driven NVH Dynamo stands out with world-class specifications of up to 20,000 rpm and 400 kW. It can be used not only for electric vehicle motor testing, but also for a wide range of systems including battery test platforms.

Motor Dynamometer 160kW ~ 400kW

KNR Systems develops its own state-of-the-art dynamo motors, engineered with advanced technology for electric vehicle motor testing. These high-performance machines feature low inertia, low vibration, and high-speed rotation, making them ideal for precise evaluation of EV powertrains. The end rings are reinforced with carbon fiber, effectively resisting deformation caused by strong centrifugal forces at high speeds. Additionally, the bearings utilize an oil mist lubrication system, ensuring both excellent cooling efficiency and enhanced durability.
