Induction motor star equivalent circuit
Conversion table for induction motors using star equivalent circuit
The conversion table was created to the best of our knowledge but there is no guaranty that it is 100% correct. Please double check critical values in the Automation Studio help before using them. If you find any errors or have any suggestions please create an issue on github.
The table uses the following notation:
|
The configuration column shows the Automation Studio configuration. Each branch in the tree is presented as a list. For example the value shown in the left picture is written as:
Induction Motor Number of pole pairs |
|
The structure column shows the same value in code. Each element of the structure is presented as a list. For example the value shown in the left picture is written as:
