Information

This approximation of a two-phase asynchronous induction machine using phasor domain for the electrical subsystem is based on the well-known steady-state equivalent circuit of such a machine. The machine is an extension of the partial Interface package model PartialBasicElectricMachine2ph of an electric two-phase machine. 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 main inductance and two stray inductances as well as a stator and a rotor resistance. 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 slip s may alter only very slowly in comparison with both the nominal frequency f=ω/(2π) and the dominant time constant of the electrical subsystem.
