#### Description

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 with the simulation period of one second.

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

`phiv`

= angle of voltage phasor
`phii`

= angle of current phasor
`phis = phiv - phii`

= angle between voltage and current phasor
`theta`

= rotor displacement angle
`epsilon = phis - theta`

= current angle

##### Note

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)

`smr.abs_vs[1]`

against `epsilon`

: RMS phase voltage against current angle
`smr.tauElectrical`

against `epsilon`

: electromagnetic torque against current angle
`phi`

against `epsilon`

: phase angle between voltage and current phasor against current angle
`theta`

against `epsilon`

: rotor displacement angle against current angle
