8 : 2.Glossary
Name Symbol Description
Total Mass M
tot
Moving Mass M
ms
It is the weight of the moving apparatus inside MOVER.
It is very important in MOVER ID, compared with the total weight.
Mms/Mtot The higher it is the more efficient is MOVER ID
Resonance frequency |Z|
nom
It is the frequency where the maximum absolute impedance is detected. It is
measured without loads on the moving mass of MOVER.
Nominal Impedance |Z|
nom
Max Impedance at Fs F
s
It is the value of the absolute impedance at resonance frequency
Suspension Compliance (1) C
ms
It is the reciprocal value of the spring stiffness. Suspensions in MOVER are
magnetic and then strongly non-linear, displacement-dependant
Linear Mass Displacement X
max
It is the displacement within the behaviour of MOVER is linear
Peak Mass Displacement X
mech
It is the maximum allowed displacement before mechanical damages can occur
DC Resistance R
e
Electric resistance in W measured at the terminal connectors of MOVER
Coil Inductance @ 100 Hz L
e
It is the inductance of the coil, measured without the moving mass at 100 Hz.
Nominal Bl Bl It is the magnetic flux generated from an infinitesimal section of the electric wire
with 1A current passing in it, multiplied per the wire length. Its unit is the Wb*m,
but an equivalent unit is the N/A: force conversion factor.
Motor Strength Factor (Bl)
2
/R
e
It is directly proportional to the efficiency of the motor
Frequency Response Hz Suggested frequency range for MOVER. It can go further but with lower efficiency.

Standard AES2-2012
Fixed support
(DD MOVER only)
n/a It is the unmovable surface where MOVER is installed.
Moving object
(DD MOVER only)
n/a It is the part of your system to be moved by MOVER.
Connection plate
(DD MOVER only)
n/a It is the external connection disk present only in MOVER DD versions.
Suspension system
(DD MOVER only)
n/a It is a system of springs flanking your MOVERs DD, required to allow them to do
their job.
Stiffness
(DD MOVER only)
k Stiffness or spring constant it is the ratio between force vs displacement of a
spring. Measurement unit N/mm (force/displacement). It is in general considered
linear and bidirectional (equal in compression and extension).
Total Stiffness
(DD MOVER only)
k
tot
It is the total stiffnesses generated by all the springs present in your external
suspension system.
Connection plate
(DD MOVER only)
n/a It is the external connection disk present only in MOVER DD versions.
8 : 3.How many MOVERs do I need?
There is no specific rule to calculate how many Movers you will need, because this number is strongly dependant on the desired effect, on
loads acting on the Movers and other factors.
It is usually suggested to use at least one Mover DD/ID each 350 kg (770 lbs) if a strong vibration/movement effect is required.
