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.
