Squirrel Cage

Modelica Standard Library

	Description
	The Squirrel Cage component models a squirrel cage/symmetrical damper cage in two axes.

	Equations
	$R_{r_{actual}} = R_{r} (1 + α (T_{hp} - T_{ref}))$ $v_{{SP}_{r}} = R_{r_{actual}} i_{{SP}_{r}} + L_{r σ} {\overset{&period;}{i}}_{{SP}_{r}}$ $\frac{2}{3} LossPower = R_{r_{actual}} (i_{{SP}_{r_{1}}}^{2} + i_{{SP}_{r_{2}}}^{2})$ $T_{hp} = {\begin{array}{c} T_{heatPort} & Use Heat Port \\ T & otherwise \end{array}$
