Information

This approximation of a two-phase synchronous machine using phasor domain for the electrical subsystem is based on the behaviour of the steady-state equivalent circuit of such a machine. This behaviour is defined by appropriate equations. The machine is an extension of the partial Interface package model PartialBasicElectricMachine2phPwr_wBalance of an electric two-phase machine including both the current balances and the power calculation.
The model has four electrical connectors of type ComplexPin (i.e. it has two electrical ports) and one mechanical rotational flange. The stator is assumed to be fixed in the housing.

The electrical submodel has two phases. Each phase consists of a constant inductance (stator's self-inductance) and an electromagnetic force (emf) realising the effect of the rotor current on the stator via the mutual inductance. All inductances are assumed to be ideal (electrically linear, no saturation).
The mechanical submodel contains a shaft which is fixed to the rotor.

Using this model, one can carry out steady-state or quasi-stationary investigations of the electrical subsystem. The mechanical subsystem may show transient behaviour which must be sufficiently slow.

Attention!!!
To ensure that the phasor domain-based model works in a quasi-stationary mode, the torque angle δ (also called rotor displacement angle) may alter only very slowly in comparison with both the nominal frequency f=ω/(2π) and the dominant time constant of the electrical subsystem.
