TPM / TPMA

TPM & TPMA High Torque
Rotary Servo Actuators

The servo actuator TPM/TPMA is characterised by compact design and highest dynamic.

TPM / TPMA overview

• up to 60% shorter overall length and much lower weight than conventional servomotor-gearhead designs
• higher acceleration rates for quicker cycle times
• high stiffness and low inertia
• eliminate need for flanges and couplings - utilizes large dual tapered roller bearings, eliminating the need for additional support bearings in the customer's application
• can be operated with most brushless servo controllers on the market
• low torque ripple for extremely smooth operation
• high positioning accuracy with < 3 arcminutes of backlash standard; reduced backlash version < 1 arcminute
• maintenance free

Specifications

• TPM - available in 5 models,
  providing 40- 1600 Nm acceleration torque and 50- 330 rpm speed
• TPMA - available in 3 models,
  providing 480-2600 Nm acceleration torque and 20- 55 rpm speed
• backlash standard < 3 arcmin;
  reduced < 1 arcmin
• efficiency > 93%
• standard version with resolver

Options

• mechanical holding brake
