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
- Load center airbag has high static stiffness and low dynamic
stiffness, strong carrying capacity, perfect performance on
amplitude variation
