modelSymmetricPolyphaseCageWinding
Symmetrical rotor cage
Extends from Magnetic.QuasiStatic.FundamentalWave.Interfaces.TwoPortExtended (Partial two port for graphical programming with additional variables).
Information
The symmetric rotor cage model of this library does not consist of rotor bars and end rings. Instead the symmetric cage is modeled by an equivalent symmetrical winding. The rotor cage model consists of
phases. If the cage is modeled by equivalent stator winding parameters, the number of effective turns,
, has to be chosen equivalent to the effective number of stator turns.
