Actuator

The RH series are compact, high torque, high rotational accuracy DC servo actuators combining a speed reducer HarmonicDrive® for precision control with a DC servo motor. The RH series is coupled with a dedicated servo driver which maximizes the performance of the series, making high rotational accuracy in compact machines and equipment possible.

• High resolution
• High directional positional accuracy
• Compact body and high-output torque

The RSF series is a high torque, high rotational accuracy AC servo actuator combining a speed reducer HarmonicDrive® for precision control with an AC servo motor.

• High output
• High positional accuracy, high rotational accuracy
• Output shaft: Shaft type

The RSF supermini series are compact, high torque, high rotational accuracy AC servo actuators combining a HarmonicDrive® with an ultra-small AC servo motor.
Coupled with the dedicated driver HA-680 for 24VDC power supply, the RSF supermini series delivers high rotational accuracy in compact machines and equipment
