FANS &
RESONATORS
The piezoelectric resonant blade element can be used as
a single fan blade, a vibration source, a chopper,or mod-
ulator.
The resonant element is easy to use and install. Its low
profile, small size, low power consumption, low EMI, and
thermal operating range make it possible to install in
places forbidden to electro-magnetic devices.
The element resonates at approximately 185 Hz. Mass
may be added to the tip of the element.to increase ampli-
tude and decrease resonant frequency, or, metal may be
trimmed from the tip to decrease amplitude and increase
resonant frequency. The elements are particularly useful
for establishing feasibility of a piezoelectric device for a
resonant application,such as a chopper.
Custom Configurations: Other piezo resonator features
are available in custom configurations, including: different
amplitudes, frequencies, sizes , thermal operating ranges
(up to 150°C), low temperature / low vacuum operation,
and non-magnetic constructions.
DESCRIPTION OF RESONATOR
P IE Z O E L E C T R IC
R E S O N A N T B L A D E
E L E ME N T
The piezoelectric resonant element is powered electro-
statically rather than magnetically. The metal portion of
the blade is driven at resonance by a piezoelectric bender
section at the base of the blade.
PRINCIPLE OF OPERATION
The resonant blade element requires an oscillating drive
signal matched to the resonant frequency of the blade.
This may be provided by a frequency generator / amplifier
or inverter circuit.
Piezo Systems provides a simple
inverter circuit (PN:
EIN-406 described on page 9).
Output frequency of the inverter is adjusted manually by
turning a trim pot on the PCB.
INVERTER DRIVE CIRCUIT
The resonator evaluation kit includes one piezoelectric
resonant element and one inverter drive circuit.
