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
