Product Description:
The working principle of the electrdynamic vibration exciter is similar to a loudspeaker whereby electrical conductor is moved
by the action of electromagnetic force in the magnetic field. The
force to accelerate the moving part is generated by the balance
between driving current and magnetic flux. Therefore, by
controlling the driving current, one can control of the vibration
generator.
The maximum acceleration level of the electromagnetic vibration
exciter is determined by the maximum current and the load. At low
frequency, displacement of moving part will impose a limitation and
the acceleration will not reach high level. The resonance frequency
of the moving element is set higher than the upper limit of the
frequency range.
The performance of vibration generator can be reflected by the
chart that display the maximum acceleration under different
frequency. By using a log-log plot, the displacement can be
restricted to a linear representation with slope of 6 dB/octave.
Features:
- Rugged suspension system and linear motion guiding, strong carrying
capacity, good guiding functions, high stability

Applications:
Vibration test is a process of exciting or
shocking some part or device to observe its reaction in real
environment. Vibration test is widely applied in many fields,
ranging from circuit board, airplane, ship, rocket, missile,
automobile, household appliance and other industrial products.
Labtone can offer you the whole vibration and
testing proposal, and provide you with the quality certificates of
products according to national and international standards,
including GB, GJB, UL, JIS, DIN, ISO, BS, MIL, IEC and ASTM
standards.
