A star winding joins one end of each phase winding at a common point.

## What it represents

A star winding joins one end of each phase winding at a common point. The external phase terminals and the common point determine the winding topology.

## How to read it

- Check whether the common point is internal or brought out as a neutral terminal.
- 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

- Show phase winding ends
- Identify common point
- Reference terminal designations

## Important distinction

A drawn star point does not mean that it is accessible for external connection.

## Facts

- Drawing role: Three-phase winding
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- 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.
