RKF Series Rotary Actuator
|
 |
Features
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. This is combined with a dedicated servo drive that fully demonstrates the performance of the RKF series of implements compact machines and equipment with a high rotational accuracy.
- compact and lightweight
- High power
- High positioning and high rotational accuracies
Used for:
- Semiconductor manufacturing systems
- FPD manufacturing systems
- Electronic component insertion machines
- Measurement analytical and test systems
