Linear Servo Conversion Kit
US PATENT NO. 7,243,562
The EMS Linear Servo Conversion
Kit provides the hobbyist with a means of linearizing the
output from a standard Futaba S-148 or S-3151 servo*. When using
servo horns to convert rotational motion into linear motion,
the amount of output displacement from the servo is not consistent
throughout the full range of the servo. The EMS Linear
solves this problem and provides much more precise control
over any application to which it is applied.
This breakthrough new product
has been engineered with the serious hobbyist in mind.
Using injection molding to achieve tolerances to less than
the thickness of a human hair and 3D computer modeling, EMS
has designed a truly innovative product. With over 1
million test cycles under its belt, the EMS Linear is built
The unique solution utilized
by the EMS Linear uses a drum to coil and uncoil the output
arm at a fixed radius to ensure linearity. The control
horn is confined in 5 degrees of motion to maximize precision.
The drum is molded from a high performance co-polymeric plastic
with high ultimate tensile strength and fatigue properties
while the housing is an industrial grade engineering resin
made to withstand the harsh requirements of everyday use.
EMS Linear "Drum"
Great for everything from throttle
control in airplanes and gas cars to animatronics to actuating
remote control submarine control surfaces. The EMS Linear
converts the torque generated by the Futaba S-148 or S-3151 servos into
more than 3 Lbf push / pull with a maximum travel of ¾ inch.
Installation takes just minutes and requires no special tools.
* Futaba S-148 / S-3151 is not included.
