Harmonic Drive

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.

• 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

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

• 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 new ultra-flat, ultra-light brushless actuators combine our high-precision/high-performance reducers with a compact, high-output brushless DC motor.

FLA actuators are available with our high-speed, high-efficiency Harmonic Planetary® gearhead or with our high-precision, high-torque Harmonic Drive® reducer. This new series is ideal for wide range of applications such as AGV wheel drives and powered exoskeletons. We offer both 24VDC and 48VDC versions to work with battery-powered applications.

Key Features:

• Ultra-Flat Shape
• Multiple Options Available: Four sizes, multiple ratios, and two voltages
• Lightweight
• Designed to operate with a wide range of third-party servo drives
