Motor  Efficiency Map Scalar Control (UI)
Positioning and objective
The aim of the test “Performance mapping – Sine wave – Motor – Efficiency map scalar UI” is to characterize the behavior of the machine in the "TorqueSpeed" area.
Input parameters like, “the maximum LineLine voltage, the maximum line current and the maximum speed” of the machine are considered.
The main difference with the test “Performance mapping – Sine wave – Motor – Efficiency map scalar Uf” is that the speed of the base speed point is not fix by a user input (Rated power supply frequency) but deduced by the internal process of computation to maximize mechanical power.
One type of command mode is available: scalar command.
Input parameters define the torquespeed area in which the evaluation of the machine behavior is performed.

Characterization of the corner point on the torquespeed curve 
In the results, the performance of the machine at the base point (base speed point) and the maximum speed (maximum speed point), set by the user are presented.
A set of curves (like a TorqueSpeed curve) and maps (like an Efficiency map) are computed and displayed.
