Actuators


RSF Series


AC servo actuators RSF series

Features

The RSF series servo actuator combines a high performance brushless servomotor with a high accuracy Harmonic Drive™ gearhead to deliver high-torque with precision. When combined with a performance matched servo drive, the RSF actuator delivers precise, reliable motion control for machines requiring both high torque and long life.
  • Compact and lightweight
  • High Torque
  • Accuracy less than 1 arc-min

Used for:

  • Semiconductor manufacturing systems
  • FPD manufacturing systems
  • Electronic component insertion machines
  • Measurement analytical and test systems
