For the hardware-in-the-loop simulation of electrical machines, such as motors or generators, dSPACE offers the Electronic Load Module. The module is optimized for high-speed operation as required for simulating electric motors such as those in electric steering systems. It can work as both a current sink and a current source to provide bidirectional current flow, i.e., it generates or consumes real current on ECU motor outputs. The Electronic Load Module can be combined with the FPGA Base Board to meet the required fast reaction times for controlling electrical machines. The FPGA Base Board computes parts of the simulation model for the electrical machine and operates the Electronic Load Module.
