A permanent-magnet synchronous generator provides an AC source using a permanent magnetic excitation system.

## What it represents

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.

## How to read it

- Distinguish machine output from the downstream converter's controlled network output.
- 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

- State machine rating
- Identify winding terminals
- Reference converter interface

## Important distinction

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

## Facts

- Drawing role: Generating source
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HPW1G6, VPW1G6 (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
