Features
The RSF series servo actuator combines a high performance brushless servomotor with a high accuracy Harmonic Drive® gearhead to deliver high-torque with precision. When combined with a performance matched servo drive, the RSF actuator delivers precise, reliable motion control for machines requiring both high torque and long life.
- Compact and lightweight
- High Torque
- Accuracy less than 1 arc-min
Used for:
- Semiconductor manufacturing systems
- FPD manufacturing systems
- Electronic component insertion machines
- Measurement analytical and test systems
