Integrating FEM Motor Data into Simscape Electrical

By Dr. James Goss (Motor Design Ltd) & Dr. Rick Hyde (MathWorks)

About this webinar

Engineers developing electric motor controls often need to simulate the nonlinear behavior of a motor which depends on things like load torque, speed and rotor angle. The motor design tool Motor-CAD solves for this nonlinear behavior using finite element (FE) analysis. This webinar will show how motor data is extracted from a Motor-CAD model and imported into a Simscape Electrical model as look-up tables. The look-up tables work in Simulink, letting a control engineer perform control design using a motor model exhibiting nonlinear behavior. This approach accounts for behaviors such as saturation and spatial harmonics. This capability is demonstrated for 3-phase machines and an example for 6-phase machines is also provided. This webinar will also show how efficiency map data from Motor-CAD can be imported into a Simcape™ Electrical™ Motor & Drive (System Level) block. This provides fast system-level simulation capability of a motor drive whilst still making accurate predictions about losses.

Highlights

  • Demonstration of exporting flux linkage from Motor-CAD to Simscape
  • Demonstration of exporting iron losses from Motor-CAD to Simscape
  • Exporting current profiles from Simscape back into Motor-CAD for accurate iron loss calculation
  • Exporting efficiency map data from Motor-CAD to Simscape
