Rotary Actuator FHA-C mini Series AC Servo Actuator

Features

  • Thin and compact
  • Hollow structure (the absolute encoder model does not have a hollow structure)
  • High torque, high stiffness, high accuracy
  • Built-in support mechanism with high-stiffness
  • Series of multi-functional control units also available
  • A 24VDC input power supply specification has been added for the absolute encoder as well just as it is with the incremental encoder model in conventional products.NEW
    New Product News Vol.6

The FHA-C mini series are AC servo actuators that provide high torque and highly accurate rotary operation.
AC Servo Actuators are comprised of a ultra-thin speed reducer HarmonicDrive® for precision control combined with a ultra-flat AC servo motor. For encoders, you can select the incremental encoder or absolute encoder.
