RSF-Mini
These brushless servo actuators utilize zero backlash Harmonic Drive® precision gears with an AC servomotor. The RSF Mini Series is designed to operate with a wide range of third party drivers as well as Harmonic Drive LLC’s DCJ Series, DDP Series, DEP Series, and HA680 drivers. The RSF Mini actuators are ideal for small robot joints as well as semiconductor and LCD manufacturing equipment.
Key Features:
- Zero backlash
- Exceptional positional accuracy
- Compact design
- High rotational accuracy
- High resolution
- Easy-to-operate dedicated driver

1) The table shows output values of the actuator.
2) All specifications are applicable for actuators mounted on an aluminum heat sink of size: 150 x 150 x 6(mm)
3) Values for saturated actuator temperature. Other values are for actuator temperature of 25°C.
4) The moment of inertia is the total value of the motor shaft and Harmonic Drive® gear converted to the output side.
5) All values are typical.
6) Quad encoder resolution is (motor shaft encoder resolution) x 4 x (gear ratio)
