Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Single-phase motor with fan](https://eloragrid.ai/symbols/single-phase-motor-with-fan) IEEE-library form of single-phase motor with fan: a single-phase motor with an associated fan identifies the driven function as well as the electrical load. ## In plain English ### What does ANSI/IEEE Single-phase motor with fan form mean? This reference locates single-phase motor with fan in Autodesk's IEEE-oriented 1 phase motors family. A single-phase motor with an associated fan identifies the driven function as well as the electrical load. Its schematic supply is separate from the airflow or installation detail. The public library uses HMO1M3M for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number. ### A simple example Trace each winding, supply and accessible neutral through the complete machine or transformer connection diagram. Keep the phase arrangement, terminal labels and any clock notation attached to the device; neither the convention label nor this educational outline supplies its ratings. ### What the drawings help you do Link the motor tag to the cabinet or auxiliary fan shown on the layout. A fan annotation identifies driven equipment, not a new electrical phase system. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted. ### This particular reference IEEE-library form of single-phase motor with fan: a single-phase motor with an associated fan identifies the driven function as well as the electrical load. A fan annotation identifies driven equipment, not a new electrical phase system. ### Terms - Winding: A coil of conductor inside an electrical machine or transformer. - Phase: One of the related AC waveforms in a power system. - Terminal: An identified point where a conductor connects.
