Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

M 3PH

IEEE / ANSI

ANSI/IEEE three-phase ac motor symbol

The three-phase motor form identifies a load connected to a documented three-phase circuit. Star/delta links, starter and overload information are separate details that should be linked rather than inferred from the machine representation.

Form evidence

Autodesk IEEE-oriented 3 Phase Motors functional form. Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

Three-phase representation does not by itself establish a star or delta connection.

M 3PH

Symbols

Three-phase AC motor

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.

A distinction that matters

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