New Electro-Dynamic Exciter System Selection Guide

The Modal Shop, A PCB Group Company, announces the release of a new system selection guide for their complete electro-dynamic exciter family of products.  The electro-dynamic exciter family includes small permanent magnet shakers rated from 110 lbf (489 N) down to 4 lbf (18 N).  Available designs include the revolutionary new SmartShaker™ with integrated power amplifier, a variety of mini, modal, dual purpose platform and accelerometer calibration shakers, and the new SmartAmp™ power amplifier.  The selection guide provides an overview of the basic shaker specifications.  A simple graphical representation of shaker systems paired with appropriate power amplifiers indicates the corresponding system force ratings.  Kit model numbers simplify the selection and ordering process, insuring that all the necessary shaker, amplifier, stingers, cooling blowers (if needed), and accessories are included.

The SmartShaker™ is a revolutionary innovation in electro-dynamic excitation.  The small footprint exciters eliminate the bulk, weight and aggravation of the traditional companion 19 inch rack-mount power amplifiers by integrating solid state power amplifier electronics inside the shaker package.  This Integrated Power Amplifier design concept follows the PCB Piezotronics® tradition of simplifying the test and measurement process by integrating the needed electronics, much like the original ICP® accelerometers miniaturized and moved the “charge amplifier” to inside the sensor package.  The small overall size (3.6 x 3.5 x 5.3 in (9.1 x 8.9 x 13.5 cm)), weighing just 7 lbs, makes it a new class of portable solution for university test laboratories and benchtop vibration studies.

The modal shaker systems range from 13 lbf to 100 lbf rating.  Each modal shaker features a through-hole armature with a chuck and collet stinger connection for easy setup and attachment to the test structure.  With all the shakers weighing under 33 lbs, they provide excellent force-to-mass ratio with nearly half the weight and twice the force as other common modal shakers.  These highly portable, rugged and easy to setup shakers are ideal for structural testing and experimental modal analysis applications, ranging from small electrical components to powertrain assemblies to large aircraft.

The innovative dual purpose platform shaker systems integrate a through-hole armature design ideal for adapting stingers for modal applications into a traditional load-bearing platform shaker for vibration control applications.  These models range from 40 lbf to 110 lbf rating, supporting static loads from 7 lb to 10 lb.

All of the shaker systems are backed by the PCB Group Total Customer Satisfaction Guarantee.  Visit the shaker family web page ( for complete specifications and data sheets on the entire line of vibration excitation products.  For additional information on these or other services, contact THE MODAL SHOP, INC., 3149 E.
