Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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 (6)

INominal

Value: 100

Type: Current (A)

Description: Nominal RMS current per phase
layout

Value: "Y3"

Type: String

Description: Braking connection layout
terminalConnection

Value: if layout == "Y3" or layout == "Y2" then "Y" else "D"

Type: String

Description: Terminal connection
connect3

Value: layout == "Y3" or layout == "D3"

Type: Boolean

Description: Connect 3rd terminal
Idc

Value: 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)

Type: Current (A)

Description: DC braking current
is

Value: 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}

Type: Current[3] (A)

Description: Phase currents
