modelDCpm
DC machine permanent magnet excited
Extends from Partials.DCpmBase (DC machine permanent magnet excited, parameter).
Information
The field (stator) winding is replaced by a permanent magnet system, no compensation and commutation poles exist.
For pu input refer to the (electrical) angular machine velocity pp*w_nom and use
L_base = R_base/(pp*w_nom)
The permanent magnet exciter flux Psi_pm can be determined either from the steady-state equation, leading to
Psi_pm = (1 - R*I_nom/V_nom)*Psi_nom Psi_nom = V_nom/(pp*w_nom)or from the induced armature voltage at nominal (compare with the synchronous machine).
