2. Circuit diagram of thyristor based speed
control DC motor:

3. Operation/function:
Voltage balance equation. The DC motor's input voltage must overcome
the counter emf as well as the voltage drop created by the armature
current across the motor resistance, that is, the combined resistance
across the brushes, armature winding and series field winding.
If any: Vm = Eb + Rm I.
