Brushless Actuator

Harmonic Drive® rotary actuators deliver both high force and outstanding positional accuracy. Harmonic Drive manufactures our own cross roller bearings, harmonic and planetary gearing, state of the art brushless servo motors and encoders. By having complete control over the design of these critical elements, we have designed the performance matched components needed to develop extremely compact actuators with the highest power density while incorporating unique features such as a hollow shaft. Performance matched precision gearing, motors, and encoders are designed to provide a power dense, cost effective solution.

The availability of these complete servo actuators eliminate the need for machine designers to individually select a motor and gearhead as well as the effort needed to characterize its expected performance. Our highly reliable and performance tested servo actuators and Servo Drives are the fastest means to get your machine design up and running.

The RKF series is compact and includes high torque AC servo actuators with high rotational accuracy, a flange output combining Harmonic Drive® strain wave gearing for precision control and an AC servo motor. The RKF Series is designed to operate with a wide range of third party drivers as well as Harmonic Drive LLC’s RTL Series, and REL Series.
