Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

IEEE / ANSI

ANSI/IEEE permanent-magnet synchronous generator symbol

This entry covers the permanent-magnet synchronous generator as it appears in an IEEE-oriented drawing library. The machine has a magnet rotor and no field winding, so output voltage rises with speed and cannot be trimmed by an excitation regulator; voltage control is done by the converter or by the load.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented 3 Phase Synchro Generator with Permanent Magnets functional form. Autodesk publishes this block under its IEEE Symbol Preview for generators. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

A permanent-magnet generator has no field winding to regulate; a wound-field synchronous generator has an exciter and regulator.

Symbols

Permanent-magnet synchronous generator

A permanent-magnet synchronous generator provides an AC source using a permanent magnetic excitation system. Any converter between this source and the AC network must be shown separately.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / Manufacturer

A distinction that matters

Permanent-magnet excitation does not mean direct grid connection is appropriate for every machine.
