These examples illustrate the connection between different ways of specifying a machine.

In particular they show the calculation of

- impedance matrix from transient data
- impedance matrix from equivalent circuit
- transient data from equivalent circuit
- equivalent circuit from transient data

for transient order n = 1 to 3.
The parameter values are chosen in such a way, that the circuit-data

(see 'Diagram layer' of the examples)

r_r[1:n], r_s} and {xsig_r[1:n], xsig_s}

remain the same for d- and q-axis. This facilitates checking.
For machines **with** field-winding (synchronous), d- and q-axis differ, if n > 1

xm[2:n] > 0, coupling terms exist in d-axis
xm[2:n] = 0, no coupling terms in q-axis

whereas for machines **without** field-winding (asynchronous), the q-axis diagram is valid for both axes d and q.
