Consider a mathematical model that describes electromechanical processes in LPIEC using lumped parameters of active elements inductor, stationary and mobile armatures:
The use of the presented modeling and measurement procedures is however limited to coil-guns using magnetic armatures. As the eddy currents and the skin effect in the armature are not considered, further investigations are needed to check whether the obtained accuracy does not result from a compensation of modeling and measurement errors, though the most influent parameter in such system is the air-gap between the coil and the armature, which define the magnetic field strength in the latter.
In previous lessons, simple armatures were applied inside a sculpture, but students had never applied armatures (buttresses) on the outside of a sculpture for support.
Latching armature relays generally are used to measure very low voltages where low thermal offsets are important.
Combined with a plastic cage to cover the armature windings, this design can eliminate costly and troublesome over-molding of the armature.
A streak camera records signals from a crushed fiber-optic diagnostic system, which is used to provide a temporal record of the armature impact with the generator stator (this diagnostic will be described in detail below).
High magnetic linkage can demagnetize the permanent magnets with high armature current during either high-current accelerations or decelerations.
Day 5: Students bring in found materials for armatures and make final decisions on the designs for their sculptures.
Similar slivers dominate the floating Glass Island, 2004, a more complex installation in which a ladderlike wooden apparatus reaches upward, its armature dotted with pins and weighed down with a mesh basket filled with ominous-looking white-topped pins resembling eggs.
Yet despite initial misgivings, Ammann quickly rallied to the notion of exposed steel and the armatures of the twin towers are powerful and dignified expressions of engineering design.
in South Beloit, Ill., has begun producing the PerformancePlus Series of clutch/brakes, which have armatures and other friction surfaces of ceramic material.
