Squirrel Cage

Squirrel Cage  Description The Squirrel Cage component models a squirrel cage/symmetrical damper cage in two axes. Equations ${R}_{{r}_{\mathrm{actual}}}={R}_{r}\left(1+\mathrm{\alpha }\left({T}_{\mathrm{hp}}-{T}_{\mathrm{ref}}\right)\right)$ ${v}_{{\mathrm{SP}}_{r}}={R}_{{r}_{\mathrm{actual}}}{i}_{{\mathrm{SP}}_{r}}+{L}_{r\sigma }{\stackrel{.}{i}}_{{\mathrm{SP}}_{r}}$ $\frac{2}{3}\mathrm{LossPower}={R}_{{r}_{\mathrm{actual}}}\left({i}_{{\mathrm{SP}}_{{r}_{1}}}^{2}+{i}_{{\mathrm{SP}}_{{r}_{2}}}^{2}\right)$ ${T}_{\mathrm{hp}}=\left\{\begin{array}{cc}{T}_{\mathrm{heatPort}}& \mathrm{Use Heat Port}\\ T& \mathrm{otherwise}\end{array}$ Variables
