Efficient engine development through modern engine test bench solutions
Engine test benches play a central role in the development, optimization and quality assurance of drive engines - both in the prototype stage and in series production. They make it possible to precisely record and evaluate a wide range of parameters such as power, torque, temperature behavior and emissions under realistic conditions. This shortens development times, detects faults at an early stage and improves engine performance in a targeted manner. Modern test bench systems are also characterized by their high level of automation, safety and adaptability and can be seamlessly integrated into existing test environments.
What advantages does an engine test bench solution with measurement technology from Delphin offer you?
- Greater efficiency in development: Automated test sequences enable fast and reliable tests - from the smallest motors to large drives.
- Maximum flexibility: Modular, adaptable systems for a wide range of testing requirements in development, series testing and endurance testing.
- Precise measurement results: Time-synchronous recording of all relevant measured variables such as temperature, pressure, torque and electrical parameters.
- High level of safety and conformity to standards: Integrated safety mechanisms and compliance with all relevant regulations.
- Cost efficiency through automation: Fully automated inspection processes with the Delphin software application save time and reduce operating costs.
- Simple integration and operation: Intuitive user interfaces and control of the entire test object periphery - from the power supply to the switching matrix.
- Reliable limit value monitoring: Permanent online monitoring of all parameters protects against damage and failures.
- Long-term accuracy: Regular calibration and maintenance ensure reliability over the entire life cycle.
Engine test benches are required in the development phase as well as in series testing and endurance testing. Typical areas of application are
- Cold resistance measurement and extrapolation of winding resistances
- Idle test
- Testing with rated load
- Test with load curve
- Overload test
- Test with braked slider
- Torque-speed characteristic curve
- Testing the voltage series
- Efficiency determination
- Heating test

Reliable complete testing for explosion-proof motors
In the type test field, explosion-protected motors are tested at five independent test stations under real operating conditions - efficiently and in parallel with development. A complete test cycle consists of several coordinated partial tests such as insulation measurement, heating test, torque measurement and runtime test. These test sequences are largely automated, ensuring consistently high quality and repeat accuracy. Control and data acquisition are carried out via the ProfiMessage systems from Delphin. These take over the precise recording of electrical and mechanical measured variables, regulate the test voltages and coordinate the entire test process. They also control complex peripheral components such as relay matrices, frequency converters and the test stand's air conditioning units. Thanks to the intelligent, PC-independent communication between the devices, information such as measured values, control commands or status messages can be exchanged directly. Integrated redundancy in the control system ensures that the test sequence can continue stably and safely even in the event of a fault - a decisive factor in safety-relevant applications such as explosion-protected motors.
