Import Efficiency Map Data from Motor-CAD

This example shows how you can import efficiency map data from Motor-CAD to parameterize the Simscape™ Electrical™ Motor & Drive (System Level) block. This provides fast system-level simulation capability of a motor drive whilst still making accurate predictions about losses.

Model Overview

Efficiency Data

The plot below shows the original scattered efficiency data from simulating a drive cycle in Motor-CAD plus the derived regular grid efficiency data for use by the Motor & Drive (System Level) block. The MATLAB® meshgrid and griddata functions determine the regular grid data.

Validation

The plot below shows efficiency values extracted from simulation results using the parameterized Simscape Electrical block.
