modelPartialBasicElectricMachine3ph
Extends from PartialBasicMachine (Basic model for generalized electric machines).
Information
This partial model is an extension of the model of a generalized electric machine
PartialBasicMachine.
Hence, it consists of the same mechanical subsystem.
The model defines a three-phase machine (if the default value of the
'number of phases'-parameter m is used).
The electrical subsystem contains two electrical plugs of type
ComplexPlug (meaning six electrical pins of type ComplexPin).
The rms values of the branch voltages and branch currents are calculated from the
corresponding phasors.
The model does not include any current phasor balance or any power calculation.
Remark:
This partial model is suitable for modeling multi-phase machines in
general.
It is not restricted to the well-known three-phase machines.
In order to model a system with different number of phases, the
'number of phases'-parameter m has to be changed in all
appearing multi-phase components and connectors.
