Test bench for electric BLDC-motors and drive systems

Mission and intended purpose of the test rig

Engineering, optimization and validation of functions, performance and endurance of electric drive systems
Analysis of drive-functions in system setup configurations (e.g. ECU and BLDC-Motors, if required including actuation gear or belt drive)
Identification of performance values and dynamic characteristics, as option including enviromental climate control

Test rig setup and modules

Load drive and modulare power-train-configuration for flexible setups
- high dynamic loading drive (e.g. up to ± 15 000 rpm, ± .. 20 Nm with optimized intertia)
- w /o intertia mass, w /o gearbox, free rotating or blocked specimen
Electric supply for the specimen
- Vehicle power circuit emulation (12 / 24 / 48 V) for power and logic supply as well as energy feed-back using high dynamic bi-directional supply units
- Option: Battery switch for connection with battery simulators
- Option: Integrated superCAPs for emulation of vehicle electric supply systems
Temperature or climate control
- Temperature (- 40 … + 150°C) and humidity control (10 .. 85 % RH)
- Standard or customer specific design of chamber, climate control units and interfaces
Measurement technology
- Torque and speed sensors with applicable range and resolution
- Current, voltage, temperature and acceleration sensors (as option)
- Option: Integration of additional electric power measurement devices

Automation system based on National Instruments VeriStand

Manual or automated analysis of characteric curves, efficiencies, harmonics, cogging curves, step response and transfer functions or longterm stability
Test sequencer with data base or NI Test Stand functionality for generic generation of specific test programs
Model-integration capability, high scalability for functional extensions (e.g. fault-insertion)
Automated report-generation with NI DIAdem
