# ANSI/IEEE Single-phase series-connected AC motor form Canonical URL: https://eloragrid.ai/symbols/ansi-single-phase-series-connected-ac-motor Publisher: Elora Grid Updated: 2026-10-28 Lookup label: HMO1M10 Drawing use: SLD, Schematic Reference families: IEEE / ANSI, Manufacturer ## Symbol convention Convention: IEEE / ANSI Form: 1 Phase AC Motor in Series Connection Autodesk IEEE Symbol Preview: 1 Phase Motors, block HMO1M10. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Single-phase series-connected AC motor](https://eloragrid.ai/symbols/iec-single-phase-series-connected-ac-motor) IEEE-library form of single-phase series-connected ac motor: this representation distinguishes the publisher's single-phase AC motor with series connection. ## In plain English ### What does ANSI/IEEE Single-phase series-connected AC motor form mean? This reference locates single-phase series-connected ac motor in Autodesk's IEEE-oriented 1 phase motors family. This representation distinguishes the publisher's single-phase AC motor with series connection. The public library uses HMO1M10 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 Document the actual field/armature or winding connection from the selected machine. Single-phase supply character does not establish an ordinary induction-motor winding arrangement. Document the actual field/armature or winding connection from the selected machine. Single-phase supply character does not establish an ordinary induction-motor winding arrangement. 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 series-connected ac motor: this representation distinguishes the publisher's single-phase AC motor with series connection. Single-phase supply character does not establish an ordinary induction-motor winding arrangement. ### Terms - AC: Alternating current: electricity whose direction changes periodically. - Winding: A coil of conductor inside an electrical machine or transformer. - Phase: One of the related AC waveforms in a power system.
