Field oriented control of a synchronous machine with a smooth (wound) rotor

In this animation the stator (three phase symmetrical winding, phase width , terminals 1U, 1V and 1W) is fed by a three phase current and the rotor (smooth rotor, distributed winding, phase width , terminals + and -) is fed by a DC current. The machine is field oriented at all times which allows the rotor speed to be dynamically controlled by controlling the rotor torque (through the torque producing component of the stator current ). The instantaneous stator currents (, and ) phase and amplitude follow from: (1) the rotor angle, (2) setting the torque producing component of the stator current, and (3) setting the flux producing component of the stator current. is assumed (load torque is zero) so that the rotor accelerates/decelerates according to the applied electromechanical torque (i.e. dynamic conditions are animated). Equations of motion were implemented as shown in 'Geogebra Physics Simulation - Tutorial' by Kornél Rokolya (Youtube).
