Three Technologies - One Actuator

Exlar's TritexTM Series actuators combine three technologies to deliver for the first time a truly simple and low cost electric alternative for fluid power actuators. Tritex actuators with built-in mechanical converters also replace electric drive systems employing ball screw or gear reducer mechanisms for a complete actuation solution.


Tritex actuators represent an all-electric actuator solution for moving and/or positioning mechanical devices in a large variety of industrial or military grade applications. Tritex actuators eliminate the need for pneumatic and hydraulic cylinders while improving position performance, reducing cycle times and eliminating the maintenance associated with fluid power devices. Ball screw mechanisms, and separately mounted gear reducers are also a thing of the past because rotary to linear converters or mechanical reducers are designed in.


Less is More

The Tritex Series of electric actuators combine a brushless servo motor, servo amplifier and position controller in a single industrial grade enclosure. This eliminates both the external servo amplifier and the expensive and failure prone cables associated with a typical servo system. Component selection, design and installation are completely elminated. Troubleshooting and debugging of individual components; gear reducers, rotary-to-linear converter mechanisms and the complex wiring layout typical of such a system are gone. The panel space for a separately mounted amplifier and installation of that amplifier are no longer necessary.


Rotary Applications

Tritex rotary motors and gearmotors provide high response and precise control of a rotatable shaft similar to that found in any electric motor. The difference is that with Tritex you can program (via your PC) the rotational speed and position of the output shaft in response to external commands. For example, the motor can be commanded to rotate at a controlled velocity and precisely stop at a pre-programmed position upon receiving a command to do so. You can also program the unit to run at a preset velocity until a switch input is received or a pre-programmed torque level is produced (against a load). Alternatively, the rotary Tritex can be set up to follow an analog signal, either voltage or current, representing torque, velocity, or position.


Signals for initiating the preprogrammed velocity and position commands come from optically isolated inputs or directly via the Modbus serial communication channel provided on each Tritex unit. Likewise, isolated output commands of the status and events allow precise coordination with your system controls or machine operator.


Optional Internal Gear Reducer

If the application requires greater torque and less speed than available with the base unit, the Tritex is available with an integral servo grade planetary gear reducer. Gear ratios of 4:1 to 100:1 allow the power of Tritex to be applied over a broad range of torque requirements.

  • Up to 1700 rpm base motor speed
  • Multiple standard and custom mounts available

Remote Amplifier Option

Normally the Tritex electronics are mounted directly within the actuator's housing. Exlar also offers the convenience of the Tritex electronics in a remote enclosure, the TRA500 for applications where physical size or temperature constraints don't allow the electronics to be mounted on the actuator. The remote Tritex electronics work with Exlar's TSM and RSM Series actuators.
