Permanent magnet synchronous machine (dynamic model)#
Block appearance in REPEAT VISION#
The Permanent magnet synchronous machine (dynamic model) block implements a generalized dynamic model of a synchronous electric machine with permanent magnets. The model assumes that the stator magnetic field induced by the permanent magnets is sinusoidal.
