FLA Rotary Actuator

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: Three sizes, multiple ratios, and two voltages
  • Light Weight
  • Designed to operate with a wide range of third-party servo drives
