M DC
DC motor
A DC motor represents a documented DC electrical load whose armature and any field winding arrangements need to be identified.

What it represents
The DC motor form identifies a documented direct-current load. Its armature path and any field supply or series connection must be established from the selected machine arrangement, rather than assuming one excitation method.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.
How to read it
- Follow armature polarity and field references separately.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.
Information to show or reference
- State DC voltage/rating
- Identify armature terminals
- Reference excitation circuit
A distinction that matters
A DC motor form is not automatically a permanent-magnet motor form.
