1) Introduction
The inertial shaker (DYN-IS-40) is used for relatively small structures
requiring excitation in low frequency bands. The shaker is directly connected
to the structure and the inertia motion of the shaker mass provides the
necessary forces to the structure. The shaker has a small, lightweight design
that provides high mobility. For this reason, it is suitable for use as a portable
shaker.

2.3) Theory of Operation
DYN-IS-40 is an electromagnetic actuator. Electromagnetic actuators are
basically a voice coil consisting of magnet and coil. The moving element can
be a coil or magnet depending on the design requirements. The moving
element is usually suspended by an elastic spring. DYN-IS-40 has a stationary
coil (drive coil) whose current is controlled to produce vibration. The
stationary magnetic field is produced by a magnet.
