Choosing a Simulation Model (Electric Motor Simulation Toolkit)
When you simulate an electric motor, you have multiple choices of the motor model functions. This topic gives a brief introduction to the built-in models of this toolkit and provides a comparison among different models to help you decide which one to choose.
The Electric Motor Simulation Toolkit allows you to simulate an AC Induction Motor (ACIM) using the constant parameter model.
To simulate a permanent magnet synchronous motor (PMSM), you can use either of the following models.
- Constant parameter model
- Variable parameter model
- Finite element analysis (FEA) model
For a switched reluctance motor (SRM), you can simulate the motor using either of the following models.
- Linear model
- FEA model
Comparing the Models
| Constant parameter model / Linear model | Variable parameter model | FEA model | |
|---|---|---|---|
| Requirements | Requires various parameters of the motor. | Requires RTT files, ANSYS motor model files, or external models that contain motor parameters information. | Requires RTT files which describe the FEA model. |
| Resources | Involves relatively smaller amount of calculations and thus requires less resources. | Involves medium amount of calculations. Requires more resources than the constant parameter model and less resources than the FEA model. | Involves heavy calculations and a more complex algorithm. Requires more resources when you compile the code on FPGA targets. |
| Fidelity | Lowest. | Medium. | Highest. The simulation is very close to the real-world situation. |
