Technical Data
An Industry Standard for over fifty years.
A Servo-Tek DC tachometer generator provides a
convenient and economical means of converting
rotational speed into an isolated analog voltage
signal suitable for remote indication and control.
While this catalog contains information on our
most popular models, we also manufacture
countless special tach generators.
Construction
Most of our DC tach generators are housed in
aluminum casings protected in accordance with
Mil-C-5541 or Mil-A-8625 or high performance
plastics. Alnico permanent magnets are used.
Armature shafts are stainless-steel, and rotate
on fully shielded stainless-steel ball bearings.
Commutators are manufactured from an alloy
containing at least 90% silver. Armature
laminations are wound with Isomid insulated wire,
over Teflon slot insulation. The entire armature
is then baked, resulting in a NEMA Class H
insulation system.
Linearity
Linearity at any speed is better than 0.1% of the
output at that RPM.
Bidirectional Operation
All Servo-Tek tachometer generators operate in
either rotational direction. That direction can be
determined by output voltage polarity. Output (in
either direction) is held to a tolerance of 0.25% of
the average output.
Stability
Optimum brush and commutator combination
gives 0.1% stability. Highly stable output gives no
evidence of long-term drift.
Breakdown Voltage
Servo-Tek DC tachometer generators are factory
tested with an AC potential of 1250 volts RMS
applied for one second between (either) terminal
and shaft. E-Series units are tested with 500 volts.
Temperature Range
Most
of
are
designed
in
ambient
-55oC to +100oC. Voltage output at 25oC will not
deviate by more than 0.01% per degree of change
within the range of -20oC to +75oC. All units are
temperature compensated, with the exception of
D-Series and E-Series tach generators.

Ripple
The ripple RMS value will not exceed 3% of the
DC value at any speed in excess of 40 RPM on
standard units. On the low ripple units, the ripple
RMS value will not exceed 1.5% of the DC value.
A peak to peak ripple of 1.5% is available on some
models.
