This example investigates the maximum torque per amps (MTPA) of a quasi static permanent magnet synchronous machine. The machines is operated at constant speed. The current magnitude is kept constant and the current angle is rotated from 0 to 360 degrees within the simulation period of one second.

In this simulation the angle is the following angles are calculated:

The intention is to compare the results of the following simulation models in one plot:


The resistors connected to the terminals of the windings of the quasi static machine model are necessary to numerically stabilize the simulation.

Plot the following variable(s)
