Model - Motor - Maps
Positioning and objective
The aim of the test “Characterization - Model - Motor - Maps” is to give maps along the three dimensions, If-Jd-Jq, for characterizing the 3-Phase synchronous machines with wound field.
These maps allow for predicting the behavior of the electrical rotating machine at a system level.
