If - I - Ψ - N
Positioning and objective
The aim of the test “Working point – Sine wave – Motor – If, I, Ψ, N” is to characterize the behavior of the machine when operating at the targeted input values If, I, Ψ, N (Magnitude of field current, magnitude of current, Control angle, Speed).
These four inputs are enough to impose a precise working point.
For instance, a working point can be chosen on the efficiency map, by identifying the field current, current, the control angle, and the speed with different curves or maps displayed in the “Performance mapping / Sine wave / Motor / Efficiency map” test. Then, the “Working point – Sine wave – Motor – If, I, Ψ, N” test allows to compute the performance for this working point.
The results of this test give an overview of the electromagnetic analysis of the machine, considering its topology.
The general data of the machine, like the machine constant and power balance, are computed and displayed. The motor convention is used to build the model.
The magnetic flux density is also computed in every region of the machine’s magnetic circuit to evaluate the design.
- “Fast computation mode” is perfectly suited for the pre-design step (Hybrid model based on Magneto-Static Finite Element computations and Park transformation theory).
- “Accurate computation mode” is perfectly suited for the final design step (Pure Finite Element modeling based on transient computations).
It also gives the capability to make comparisons between the results obtained from the measurements and those obtained with FluxMotor.
The following table helps to classify the test “Working point – Sine wave – Motor – If, I, Ψ, N”.
