A single-phase AC motor represents a load supplied from a documented single-phase source.

## What it represents

A single-phase AC motor represents a load supplied from a documented single-phase source. Its actual winding, starting component and terminal arrangement require the selected motor connection diagram.

## How to read it

- A simplified motor image does not show every start or run winding.
- 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 voltage
- Reference motor terminal diagram
- Show starting/protection arrangement

## Important distinction

Single-phase supply and the motor's starting method are different drawing attributes.

## Facts

- Drawing role: Rotating or linear load
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HMO1M9, VMO1M9 (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.
