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.

First referenceCompare with

HMO1M16

IEEE / ANSI

ANSI/IEEE Single-phase synchronous motor form

This reference locates single-phase synchronous motor in Autodesk's IEEE-oriented 1 phase motors family. This representation identifies a single-phase synchronous machine function. The public library uses HMO1M16 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

Drawing use: SLD / Schematic
Application: Power distribution
Reference family: IEEE / ANSI / Manufacturer
Form evidence: 1 Phase Synchronous AC Motor. Autodesk IEEE Symbol Preview: 1 Phase Motors, block HMO1M16. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

Synchronous operation differs from induction-motor operating slip.
