Industry-Leading DC Powered Rotary Actuator

The Tritex II DC powered rotary actuator houses a servo drive, digital positioner and servo motor in a single, compact package. These advanced actuators offer the highest power density and smallest footprint servo driven devices on the market. Their small size and innovative design make it easy to incorporate a fully electronic solution in the space of your existing hydraulic or pneumatic cylinder. Now you can precisely control motion and solve your application requirements with a single, fully integrated device.

Programmable Power and Performance

The DC powered Tritex II rotary actuators integrate a 750 W servo amplifier with a highly capable motion controller. These rotary motors and gear motors consistently deliver high response and precise control. Using your PC, you can quickly and easily program the actuator to follow an analog signal (either voltage or current), representing your preferred torque, velocity, or position. Gear ratios from 4:1 to 100:1 provide ample power to meet a wide range of applications that demand high turndown and accuracy. Standard features include analog following for position, compound moves, move chaining, and individual torque control for each move. Tritex II is the ideal solution for most motion control applications.

Compact Size and Low Operating Costs

This robust rotary actuator solution delivers outstanding reliability and performance, and features a small form factor. With the servo drive and digital positioner housed in a single, sealed package, space requirements are minimized. The innovative integral design eliminates labor costs associated with mounting and wiring panels. This solution simply requires an economical DC power cord and a standard communication cable for digital and analog I/O. Also there is no need for expensive, high maintenance servo cables, and associated long distance signal issues are a thing of the past.

Other Advantages

  • Maximum power, precision and speed in a compact package
  • DC electronics for mobile and/or battery powered applications
  • Superior replacement for pneumatic and hydraulic cylinders
  • Programmable software enables automated sequencing
  • Multiple feedback types to best suit any application
  • Digital and analog I/O and popular communication networks
  • Engineered for closed loop servo systems
  • 100% duty cycle for hundreds of millions of strokes
  • Sealed housing for extended life and reduced maintenance

Output Torque at Motor Speed for 10,000 Hour Life. Two torque ratings for the RDG gearmotors are given in the table above. The left hand columns give the maximum (peak) allowable output torque for the indicated ratios of each size RDG gearmotor. This is not the rated output torque of the motor multiplied by the ratio of the reducer. It is possible to select a configuration of the motor selection and gear ratio such that the rated motor torque, multiplied by the gear ratio exceeds these ratings. It is the responsibility of the user to ensure that the settings of the system do not allow these values to be exceeded. The right hand columns give the output torque at the indicated speed which will result in 10,000 hour life (L10). The setup of the system will determine the actual output torque and speed.

Output Torque at Motor Speed for 10,000 Hour Life.Two torque ratings for the RDG gearmotors are given in the table above. The left hand columns give the maximum (peak) allowable output torque for the indicated ratios of each size RDG gearmotor. This is not the rated output torque of the motor multiplied by the ratio of the reducer. It is possible to select a configuration of the motor selection and gear ratio such that the rated motor torque, multiplied by the gear ratio exceeds these ratings. It is the responsibility of the user to ensure that the settings of the system do not allow these values to be exceeded. The right hand columns give the output torque at the indicated speed which will result in 10,000 hour life (L10). The setup of the system will determine the actual output torque and speed.
