ANSI/IEEE Series-excited DC motor form
IEEE-library form of series-excited dc motor: a series-excited DC motor connects its documented field winding in series with the armature circuit.
In plain English
What does ANSI/IEEE Series-excited DC motor form mean?
This reference locates series-excited dc motor in Autodesk's IEEE-oriented dc motors family. A series-excited DC motor connects its documented field winding in series with the armature circuit. Both winding and armature terminals need to remain identifiable in expanded schematics. The public library uses HMO1M7 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Trace each winding, supply and accessible neutral through the complete machine or transformer connection diagram. Keep the phase arrangement, terminal labels and any clock notation attached to the device; neither the convention label nor this educational outline supplies its ratings.
What the drawings help you do
Follow the field current through the armature path. A series field and a shunt field have different circuit connections. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.
