No load curve
Positioning and objective
The aim of the test “Characterization - Open circuit – Generator – No Load” is to characterize the behavior of the machine when running in a no–load state.
The analysis of the machine’s no-load characteristics is a first step to evaluate the
relevance of the machine design regarding not only parameters such as: topology,
winding architecture, composition of coils and choice of materials, but also the
impact of the applied field current value in the magnetic saturation of the
machine.
Warning: When a delta winding
connection is considered, the computation doesn’t consider circulation currents.
That can lead to a different result than what expected in transient
computation.
In such case, it is recommended to perform a transient computation in Flux® environment. The application “Export to Flux” allows exporting the model with the corresponding scenario ready to be solved.
The following table helps to classify the test “Open circuit – No Load”.
| Family | Characterization |
|---|---|
| Package | Open circuit |
| Convention | Motor & Generator |
| Test | No Load |
