Separately excited DC motor
A separately excited DC motor has a documented field circuit supplied separately from the armature circuit.
IEEE-library form of separately excited dc motor: a separately excited DC motor has a documented field circuit supplied separately from the armature circuit.
In plain English
This reference locates separately excited dc motor in Autodesk's IEEE-oriented dc motors family. A separately excited DC motor has a documented field circuit supplied separately from the armature circuit. The schematic must show both supplies and their relevant controls. The public library uses HMO1M12 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
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.
Trace the field source independently from armature power. Separately excited and series-excited motors do not share the same field-current path. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

These public references support the explanation and provide further detail. Their graphics and downloadable files remain with their publishers.
Public IEEE-oriented DC Motors table explicitly lists HMO1M12 as DC Motor - Independent Excitation. This supports the vendor convention context, not reproduction of the publisher graphic.
This illustration was authored independently by Elora Grid to explain the concept. It is not reproduced from a customer drawing, an official standard graphic or a manufacturer CAD file. Its correspondence to an exact IEC or IEEE symbol identifier has not been certified.
