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.
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.
Assembly of rotor/pulleys and armatures
is performed on Partsembler indexing carousels of cone-lock design.
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.
