Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Single-phase synchronous motor](https://eloragrid.ai/symbols/iec-single-phase-synchronous-motor) IEEE-library form of single-phase synchronous motor: this representation identifies a single-phase synchronous machine function. ## In plain English ### What does ANSI/IEEE Single-phase synchronous motor form mean? 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. ### 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 State the supply, starting and any excitation interface required by the actual motor. Synchronous operation differs from induction-motor operating slip. State the supply, starting and any excitation interface required by the actual motor. Synchronous operation differs from induction-motor operating slip. 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 synchronous motor: this representation identifies a single-phase synchronous machine function. Synchronous operation differs from induction-motor operating slip. ### 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.
