TPM+ HIGH TORQUE rotary servo actuators

  • TPM+ HIGH TORQUE: High torsional rigidity and high power density. Two or three-stage servo actuator for heavy-duty applications

Stronger. More compact. Higher torsional rigidity.

This servo actuator takes you even further: with 50% more torque and improved performance.

Even better power transmission due to the more rigid drive train offers higher acceleration and shorter cycle times. Effectiveness from which you benefit. An additional planet in the gearbox significantly increases the torsional rigidity of the particularly short and light servo actuator. The coupling-free integration of the motor and gearbox and the efficient attachment of motor instruments are the formula for success.

Your benefits

Greater precision

The high torsional rigidity and the ample torque reserve ensure extremely stable drive control in the case of disturbing forces.

This reliable servo actuator therefore guarantees the highest precision for your tasks.

Small footprint for your machine

The short installation length of the servo actuators enables a more compact design of your machines and plants

Improved efficiency

The low moment of inertia and high power density mean the power which is supplied is utilized more efficiently

Our know-how – your benefit

The TPM+ product family is convincing. With its dynamics, torque and torsional rigidity! In combination with extremely short overall lengths and high power density, this ensures greater operating efficiency in all your production applications.

Increased productivity and higher OEE

  • Bayonet-coupling connector for fast installation
  • External surfaces with smooth design reduce proneness to fouling

Simplified machine design and smaller footprint

High power density and short overall length for a compact machine design

Reliability and service life

Robust bearing with long service life
