Aug 02, 2018· When the armature windings and field windings are connected in series, the motor is referred to as a “series wound” DC motor. Being connected in series means the current through the armature and the field windings is equal (I total = I a = I f ), which allows the motor to draw a significant amount of current.

Second, it's a matter of definition. A shunt-wound motoruses the same power source in parallel for the field and armature, using a mechanical commutator. Replace the commutator with a Hall-effect sensor and electronic switch and it's a brushlessmotor, but the term "shunt-wound" is not applied. They're still the same basic design, though.
