Home / Products / Exlar Automation / Rotary Actuator / Motor / Drive / Tritex II® DC Rotary Actuator
Actuation Division
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.
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.
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.

RDM/G Motor Type RDM = Tritex II DC Rotary Motor (60, 75, 90 mm) RDG = Tritex II DC Rotary Gearmotor (60, 75, 90 mm)
AAA = Frame Size BBB = Gear Ratio C = Shaft Type D = Connections E = Housing Options F = Brake Options GG = Feedback Type
HHH-HH = Motor Stators Motor options are described with a 3-digit code. The first digit calls out the stack length, the second digit designates the rated bus voltage, and the third digit identifies the number of poles. Please refer to the mechanical/electrical specifications for motor torque and actuator rated force.
III = Voltage JJJ = Option Board
* Some options are not available with every configuration. For options or specials not listed above or for extended temperature operation, please consult Exlar Applications Engineering.
IP Ratings for Exlar Actuators
*Power supply current is based on software current limit, not thermal limit. Consideration for peak current should also be considered when sizing power supplies. For output torque of RDG gearmotors, multiply by ratio and efficiency. Please note maximum allowable output torques found at bottom of page. **Ratings based on 40˚ C ambient conditions.
*Add armature inertia to gearing inertia for total inertia.
Side load ratings shown above are for 10,000 hour bearing life at 25 mm from motor face at given rpm.
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.
For RDG gearmotors, multiply torque by ratio and efficiency. Divide speed by gear ratio. * RDM060 test data derived using NEMA recommended aluminum heatsink 10” x 10” x 1/4” at 40°C ambient
