The Benefits of Using engine test bench

Engine Test Bench - What's Behind It

The motor test bench plays a central role in the ongoing development of electromobility - a sector characterized by innovation and technological progress. At a time when the demand for sustainable and efficient transport solutions is increasing, the motor test bench offers an indispensable platform for the development, optimization, and validation of the electric motor. By using the motor test bench, manufacturers can ensure that they meet the high reliability and performance requirements that are crucial for success in the electric mobility market. This is important not only to ensure vehicle performance and safety, but also to comply with strict international standards and regulations, and an essential part of this process is HiL (Hardware-in-the-Loop) testing, which allows the interaction between the electric motor and the vehicle electronics to be simulated and analyzed under real-life conditions.

The engine test bench is therefore an essential tool for the development, validation, and optimization of the electric motor. The test facilities are designed to provide precise data on the performance of a motor by measuring operating parameters such as power, torque, efficiency, and behavior under different load conditions.

Our engine test bench is designed for comprehensive testing of various performance parameters of AC/EC or BLDC motor units. For the tests, the test specimen is coupled with a torque measuring shaft and a static or dynamic brake load or a tool holder. This configuration makes it possible to map various test scenarios and collect precise data on the performance of the motors. Find more information in our download section also. 

With our in-depth understanding of the dynamics of the electromobility market, we support you, for example, in the development of an optimal drive system. This includes the careful selection of the motor type and size, the coordination of the power electronics, and the integration into the overall system to ensure harmonious and efficient operation. Taking into account functional requirements and safety-relevant functions of the drive, we use advanced simulation tools such as FluidFEM to verify concepts before mass production. This enables us to meet complex requirements in the field of drive technology and support you throughout the entire development process.

Our SCHENCK ex “Formula 1” test bench allows us to fine-tune any type of engine with speeds up to 18,000 rpm and powers up to 1,000 hp.

The engines are then equipped with numerous sensors (temperature, pressure, knock, cylinder pressure, etc.) in order to carry out tuning under optimum safety conditions.

The ROTOTEST test bench is comparable to a set of engine benches coupled to each drive wheel of the vehicle. Unlike a traditional (roller) test bench, it is an extremely precise measuring instrument thanks to high-resolution torque sensors measuring the force directly at the wheel hubs.

This new type of dynamometer is similar to a roller dynamometer but has much greater precision and testing flexibility. Among the main advantages, we find the absence of slippage between the wheels and the bench, the very low inertia of the system as well as a precise and independent measurement of all losses by friction.

In addition, this system does not damage the tires and adapts to all vehicles, regardless of running gear geometries.

Passing to the bench makes it possible to draw all the quintessence of the mechanics and to optimize engine performance as much as possible according to predefined reliability criteria. In addition, this makes it possible to guarantee the safety of the engine during the first run and after an often expensive engine reconstruction, the mechanical aspect then being validated upstream on a test bench.
