Test example: Series excited DC machine at single-phase AC
voltage started with a series resistor
At sinusoidal source voltage, a series resistor limiting the
armature current, is reduced according to a ramp, causing the DC
machine to start, and accelerating inertias against load torque
quadratic dependent on speed, finally reaching nominal speed.
Simulate for 2 seconds and plot (versus time):
- dcse.ia: armature current
- dcse.wMechanical: motor's speed
- dcse.tauElectrical: motor's torque
Default machine parameters of model DC_SeriesExcited are
used.
Note:
Since both the field and the armature current are sinusoidal, the
waveform of the torque is the square of sine. Due to the additional
inductive voltage drops, output of the motor is lower, compared to
the same motor (DCSE_Start) at DC voltage.
