TPM+ DYNAMIC rotary servo actuators

  • TPM+ DYNAMIC: Outstanding dynamics, compact dimensions and extremely smooth running. Actuator with two-stage gearbox designed primarily for rotary applications

Dynamic. Shorter. Quieter.

Experience extraordinary dynamics thanks to modern motor technology with high power density, a low moment of inertia and optimal torsional rigidity. Benefit from the reduced installation length: The coupling-free connection integration of the motor and gearbox and the space-saving attachment of motor instruments make the TPM+ DYNAMIC over 50% more compact than conventional gearbox motors. Helical-toothed precision planetary gearboxes ensure low-vibration and silent operation.

Your benefits

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

Enhanced productivity

The increased rigidity and dynamics generate higher output in your machine

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
