Information

Model of a DC Machine with series excitation.
Armature resistance and inductance are modeled directly after the armature pins, then using a AirGapDC model.
The machine models take the following loss effects into account:

No saturation is modelled.
Series excitation has to be connected by the user's external circuit.
Default values for machine's parameters (a realistic example) are:

stator's moment of inertia 0.29 kg.m2
rotor's moment of inertia 0.15 kg.m2
nominal armature voltage 100 V
nominal armature current 100 A
nominal torque 63.66 Nm
nominal speed 1410 rpm
nominal mechanical output 9.4 kW
efficiency 94.0 % only armature
armature resistance 0.05 Ohm at reference temperature
reference temperature TaRef 20 °C
temperature coefficient alpha20a 0 1/K
armature inductance 0.0015 H
excitation resistance 0.01 Ohm at reference temperature
reference temperature TeRef 20 °C
temperature coefficient alpha20e 0 1/K
excitation inductance 0.0005 H
stray part of excitation inductance 0
armature nominal temperature TaNominal 20 °C
series excitation nominal temperature TeNominal 20 °C
armature operational temperature TaOperational 20 °C
series excitation operational temperature TeOperational 20 °C
Armature resistance resp. inductance include resistance resp. inductance of commutating pole winding and compensation winding, if present.
Parameter nominal armature voltage includes voltage drop of series excitation;
but for output the voltage is split into:
va = armature voltage without voltage drop of series excitation
ve = voltage drop of series excitation
