Rotary Actuator FHA-C Series AC Servo Actuator

Features

  • Thin and compact
  • Hollow structure
  • High torque, high stiffness, high accuracy
  • Built-in support mechanism with high-stiffness
  • Series of multi-functional control units also available

The FHA-C series AC servo actuators' flat shape and hollow bore structure makes downsizing of machinery and equipment possible, and makes structuring simple.

The values listed above show the typical values of the output shaft.

  • *1Indicates typical characteristics when combined with a Harmonic Drive Systems screwdriver (driven using an ideal sine wave). (Ambient temperature of 25℃)
  • *2Value with saturated temperature rise when installed on an aluminum radiation plate (17C: □300 × 15 t, 25C: □350 × 18 t, 32C: □400 × 20 t, 40C: □500 × 25 t [mm]).
  • *3The inertia moment and mass values are for when there is no brake.
  • *4The output shaft resolution is (motor shaft encoder resolution when multiplied by 4) x (reduction ratio).
