recordDcBrakeSettings
Setting for DC current braking
Information
Lets the user choose the layout, and determines the necessary DC current for DC current braking of an induction machine.
The icon shows the four layout variants. Phases with half the current are depicted with half the line thickness, phases with zero current are depicted with dashed line.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| SI.Current | INominal | 100 | Nominal RMS current per phase |
| String | layout | "Y3" | Braking connection layout |
| Results | |||
| String | terminalConnection | if layout == "Y3" or layout == "Y2" then "Y" else "D" | Terminal connection |
| Boolean | connect3 | layout == "Y3" or layout == "D3" | Connect 3rd terminal |
| SI.Current | Idc | if layout == "Y3" then INominal*sqrt(2) elseif layout == "Y2" then INominal*sqrt(3/2) elseif layout == "D2" then INominal*3/sqrt(2) else INominal*sqrt(6) | DC braking current |
| SI.Current[3] | is | if layout == "Y3" then Idc*{1, -1/2, -1/2} elseif layout == "Y2" then Idc*{1, -1, 0} elseif layout == "D2" then Idc*{2/3, -1/3, -1/3} else Idc*{1/2, -1/2, 0} | Phase currents |
