General Operation

The EL100 series of actuators function in the same manner as a brushless servomotor. The
EL100 actuator must be connected to a servo drive controller to properly commutate the motor
and control the torque, speed and position of the actuator. This rotary motion is translated into
linear motion by the internal planetary roller screw mechanism of the EL series linear actuator.
The rotary motion of the motor and the linear motion of the actuator correspond to the following
relationships:
/
Motor Torque in − lbf × 2π × Efficieny
=
All of the above relationships require proper anti-rotation of the EL series actuator rod. The
unique design of the EL series linear actuators allows the extending rod to rotate. This
simplifies the setup of the actuator by allowing the user to rotate the rod and thread it in and out
of the actuator for mechanical attachment or system testing.
This feature also requires that the rod be kept from rotating when used in its dedicated
application to insure proper linear motion. In most applications, such as those where the load is
coupled to linear bearings or some other support device, the load cannot rotate, providing anti-
rotation for the extending rod of the actuator.
For applications in which the load is free to rotate, Exlar offers anti-rotation systems. Contact
Exlar engineering if the application requires a dedicated anti-rotation system.
