Electric Motor HIL Solution

Electric motor simulation

  • High-precision digital capturing of 3-phase PWM signals
  • Fast signal measurement and analysis
  • Simulation of various position sensors
  • High timing resolution
  • Various additional multipurpose signals


Purpose
The EMH (electric motor HIL) solution is based on the DS5202 FPGA Base Board. It gives you all the I/O channels that are needed for HIL simulation of electric motors, such as high-precision digital capturing of 3-phase PWM signals and position sensor simulation, plus several digital and analog I/O channels. It combines the features of the DS5202 PWM and PSS solutions with many additional multipurpose channels, and enables efficient testing of electronic control units (ECUs) for electric motors on a single I/O board.

Use Case
A typical use case is a hardware-in-the-loop (HIL) simulation where the electric motor including the electronic power stage is simulated by means of the dSPACE modular real-time hardware. Simulation models like dSPACE Automotive Simulation Models – ASM Electric Components Library are used for simulating the electric components. The gate driver signals (typically PWM signals) coming from a controller are measured by the DS5202 EMH solution, and calculated motor current signals are sent back to the controller by means of analog voltage signals, which can also be provided by the DS5202 EMH solution. In addition, the DS5202 EMH solution provides the necessary position sensor signals for the ECU.
