A three-phase AC motor is a load supplied from three documented phases.

## What it represents

A three-phase AC motor is a load supplied from three documented phases. Its winding connections, protection and starter are recorded in the power schematic or linked motor data.

## How to read it

- Check whether the drawing shows a simplified load or an expanded terminal connection.
- 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 supply and rating
- Reference winding connection
- Show starter and overload protection

## Important distinction

A three-phase motor representation does not specify star or delta terminal links by itself.

## Facts

- Drawing role: Rotating or linear load
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HMO13, VMO13 (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.
