modelAsynchronBase
Asynchronous machine base, 3-phase abc
Extends from AsynTransform (Park transform).
Information
The stator contains one winding each in d-axis, q-axis, o-axis.
The rotor contains n_r windings each in d-axis and q-axis (at least one).

Parameters.Asynchron !
v, i: stator-voltage and -current abc v_s, i_s: stator-voltage and -current dqo v_rd[n_r], i_rd[n_r]: rotor-voltage and -current d-axis v_rq[n_r], i_rq[n_r]: rotor-voltage and -current q-axis
The equations are valid for all dqo reference systems with arbitrary angular orientation.
Special choices are
omega[2] = omega defines 'stator' system, rotating with stator frequency omega[2] = w_el defines 'rotor' system, rotating with rotor speed el (el = mec*pp) omega[2] = 0 defines the inertial system, not rotating. with omega[2] = der(term.theta[2])
