gives the opportunity to observe the stator current, the speed, the torque, and the ux
of SM and also the DC voltage. The scope Voltages xes the input and output volt-
ages of the inverter, and the scope Power, the active power consumed from the grid.
The following schedule is simulated: initial excitation, speeding-up to the speed of
2000 rpm (with eld weakening), reverse to −500 rpm, reverse to 100 rpm; the load
torque is 250 N-m. The plots of speed, torque, ux linkage, and mains power are
given in Figure 5.109. The processes of SM magnetization and ux weakening at
speeds more the 1500 ...
