modelPartialBasicElectricMachine2phPwr
Basic model for two-phase electric machines (no current phasor balance, but using power calculation)
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 two-phase machine.
The electrical subsystem contains four 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.
Two values of active and reactive power (for each branch)
are computed and made available via two output signals.
Remark:
This partial model is suitable only for modeling two-phase machines.
