Harmonic Drive

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

• Compact, lightweight, high output
• Standard lineup of actuators with a brake
• High-precision positioning
• Wide operation range
• For 24VDC power supply
• Robust structure (Flexible cable used for the encoder cable)

The RSF-B mini series are AC servo actuators combining a speed reducer HarmonicDrive® for precision control with a high speed, high response AC servo motor, and feature high torque and precision rotary operation.

• Compact, lightweight, high torque
• Advanced positioning accuracy
• Stable controllability

Offers extensive variation: hollow, flat, high torque

• Hollow, flat structure
• Torque/volume ratio is five times that of the direct drive motor (HDS material)
• Series created with 20N・m to 3400N・m torques
• Tailor specifications including output bearings, speed reducers and motor armatures to meet customer-specific needs.
• Comes standard with a 17-bit absolute encoder
• Combined with the HarmonicPlanetary® HPF Series for high-speed rotation (Model nos: 25, 32)
• SG Type Model No. 45 added to SHA Series

The component type HarmonicDrive® for this series is made better than previous models.Its better torque capacity and longer service life delivers better torque to each model in the series.

• High strength
• High load capacity
• Long service life (better rated life)
• Backlash-free
• High efficiency
