WebApr 10, 2024 · (b) Avoid Force Shunts. A force shunt is any device or path through which a portion of the force flow or load is diverted. Whereas “shunt” typically describes electrical current, the concept remains true for the “flow” of mechanical force. Avoiding force shunts is critical for accurate weighing of tanks, platforms, or scales. WebDec 29, 2015 · In a DC shunt motor, the armature and field (shunt) windings are connected in parallel. A parallel circuit is also known as a shunt circuit; thus, the term, “shunt motor” is used. Image credit: National Instruments Corporation. Where: I total = supply current. I a = current though armature windings. I sh = current through shunt (field ...
WebA shunt is a hollow tube surgically placed in the brain (or occasionally in the spine) to help drain cerebrospinal fluid and redirect it to another location in the body where it can be reabsorbed.
