This is a simplified model of a permanent magnet excited DC machine. All losses except ohmic losses of the armature winding are neglected. The armature resistance is dependent on temperature. Additionally, the armature inductance is implemented. Induced voltage and generated torque are calculated in the electro-mechanical converter. By extending from the PartialMachine, shaft flange, inertia of stator and rotor as well as a conditional support/housing flange and a conditional thermal connector are inherited.
