IEEE / ANSI

ANSI/IEEE Electromagnetic brake actuator form

This reference locates electromagnetic brake actuator 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.

Drawing use: Schematic
Application: Control circuits
Reference family: IEEE / ANSI / Manufacturer
Form evidence: 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.

A distinction that matters

The symbol does not specify braking torque or release timing.
