TPM+ Rotary Servo Actuators

  • TPM+ dynamic: Power with small installation space and very smooth running Actuator with two-stage gearbox designed primarily for rotary applications

  • TPM+ high torque: High torsional rigidity and superior power density. Two or three-stage servo actuator for heavy-duty applications
  • TPM+ power: high torque, small installation space Single or two-stage motor/gearbox combination for linear and rotary applications

More productive – more efficient – more precise

With the servo actuator TPM+ , precision planetary gearboxes and synchronous servo motors are integrated without a clutch for a unit that is flexible in its application. Customers appreciate its power, torque and torsional rigidity in a more compact space. Short overall lengths, high power-density and smooth operation, along with practical, graduated performance settings help promote operating efficiency and cost of ownership.

Increased productivity
The benefits for your machinery and plants: An actuator with a low moment of inertia and an extremely rigid drive train provide for maximum precision and power. A decisive increase in productivity 

Higher efficiency
Low torsional backlash, an output bearing with a high degree of tilting rigidity and integration of the gearbox pinion in the motor shaft result in: smaller motors, reduced energy consumption and lower investment costs.

Higher precision
Low levels of operating noise due to helical teeth and outstanding control properties provide enhanced precision in your machinery and plants. The result: truly cost-effective products
