SCALEXIO for Electric Motors: Flexibility, Speed and Power

Comprehensive solutions for HIL tests of electric motors
  • Freely programmable FPGA
  • Simulation models for electric motors
  • Electronic load with energy recovery
Wixom, Michigan, September 05, 2013: dSPACE has announced the introduction of an even more flexible and powerful solution for hardware-in-the-loop (HIL) testing of electric motors. Combining the flexible architecture of SCALEXIO with its freely programmable FPGA board DS2655, plus a scalable electronic load, users can test electric motor control systems in a more realistic environment by emulating the real motor and generator currents. 
User-Programmable FPGA
The powerful SCALEXIO DS2655 FPGA Base Module is user-programmable to define high-fidelity, custom models for simulating complex, highly dynamic systems. In a SCALEXIO HIL simulator, the FPGA is frequently used for simulating electric motors requiring very fast, computationally intensive simulation in applications such as hybrid vehicles or wind turbines. Modules can be mounted on the DS2655 base board to provide the necessary number of I/O channels.
The FPGA device can be configured graphically with standard dSPACE tools, so that users can react flexibly to new requirements, such as new I/O interfaces or faster simulation. dSPACE also provides the simulation models for HIL tests of electric motors and associated power electronics and batteries.
Electronic Load with Energy Recovery  
The solution for electric motor simulation includes a scalable dSPACE electronic load module. It emulates motor and generator currents of up to 100 A at voltages of up to 60 V. With this voltage range, the load allows auxiliary to be emulated in vehicle electrical systems of up to 48 V. The electronic loads can be used in parallel to provide higher current capability.
The Electronic Load Module features energy recovery capabilities, which considerably increases overall system efficiency and provides energy saving during testing. Lower energy consumption also means that less heat is generated, and therefore, less active cooling is necessary. Additional benefits are reduced space requirements and noise.
System Structure
The Electronic Load Module can be integrated within the SCALEXIO system or installed externally. The ECU under test can be connected directly to the Electronic Load Module, resulting in short power signal connection and reduced possible signal interference.
dSPACE will be presenting a demo system at the eCarTec trade fair in Munich on October 15.-17., 2013 (booth 503, hall A6).
