# ANSI/IEEE Electromagnetic brake actuator form Canonical URL: https://eloragrid.ai/symbols/ansi-electromagnetic-brake-actuator Publisher: Elora Grid Updated: 2026-10-28 Lookup label: HSV1Y4 Drawing use: Schematic Reference families: IEEE / ANSI, Manufacturer ## Symbol convention Convention: IEEE / ANSI Form: Magnetic Brake Autodesk IEEE Symbol Preview: Solenoids, block HSV1Y3. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Electromagnetic brake actuator](https://eloragrid.ai/symbols/iec-electromagnetic-brake-actuator) IEEE-library form of electromagnetic brake actuator: this representation identifies an electromagnetic brake actuated through its documented electrical circuit. ## In plain English ### What does ANSI/IEEE Electromagnetic brake actuator form mean? This reference locates electromagnetic brake operating mechanism in Autodesk's IEEE-oriented solenoids family. This representation identifies an electromagnetic brake actuated through its documented electrical circuit. The public library uses HSV1Y3 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number. ### A simple example Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence. ### What the drawings help you do Show coil supply, control and any suppression separately. The symbol does not specify braking torque or release timing. Show coil supply, control and any suppression separately. The symbol does not specify braking torque or release timing. 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 electromagnetic brake operating mechanism: this representation identifies an electromagnetic brake actuated through its documented electrical circuit. The symbol does not specify braking torque or release timing. ### Terms - Normally open / normally closed: The contact state in the normal condition defined for the drawing. - Coil: A wound conductor that can produce a magnetic field when energised. - Signal: Electrical information passed between devices, rather than necessarily the main power supply. Concept diagram: Identify the device and form → Read the connections and state → Check the equipment reference A guide to reading this reference.
