What it represents
This representation distinguishes the publisher's derived or shunt-excitation DC motor form.
Document the field connection separately from the armature circuit.
Shunt, series and separately supplied field arrangements are different connection topologies.
How to read it
- Document the field connection separately from the armature circuit.
- Shunt, series and separately supplied field arrangements are different connection topologies.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Document the field connection separately from the armature circuit.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
Shunt, series and separately supplied field arrangements are different connection topologies.
