General Operation
The Tritex Series of actuators and motors function in the same manner as a brushless
servomotor. The servo amplifier is used to rotate the motor at controlled speed and
torque, and for controlled numbers of revolutions and move times. This rotary motion is
translated into linear motion by the internal planetary roller screw mechanism of the TLM
Series linear actuator. The rotary motion of the motor and the linear motion of the
actuator correspond to the following relationships:
Linear Distance Traveled (in) = (Motor Revolutions)*(Roller Screw Lead)
Linear Speed (in/sec) = ((Motor RPM) / 60)*(Roller Screw Lead)
Linear Force (lbf) = ((Motor Torque (in-lbf))*(2

)*(efficiency)) / (Roller Screw Lead (in))
All of the above relationships require proper anti-rotation of the TLM Series actuator rod.
TLM & TSM Series Linear Actuator Anti-rotation Option
The unique design of the TLM 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 the anti-rotation systems
shown below. The drawings on the next page show the rod and bushing on only one
side of the actuator. For long stroke actuators, the rod and bushing are required on both
sides of the actuator.
