What it represents
A permanent-magnet DC motor uses a permanent magnetic field rather than a separately connected field winding. Its armature and control connections still require product documentation.
How to read it
- Do not draw a separate excitation supply unless the actual motor has one.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Identify armature polarity
- State motor rating
- Reference speed/control circuit
A distinction that matters
Permanent-magnet construction differs from a separately excited DC field winding.
