Harmonic Drive LLC has announced a new RSF-5 miniature actuator with an integrated servo drive. This product eliminates the need for an external drive and greatly simplifies cabling while retaining high-positional accuracy and torsional stiffness in a compact housing.

The RSF Mini and Supermini series is a family of compact actuators that deliver high torque with exceptional accuracy and repeatability. As part of the RSF Supermini family, an integrated servo drive version utilizing CANopen communication is now available. Since it communicates via CANopen, only 4 conductors are needed: CANH, CANL, +24VDC, 0VDC. A single-turn 14bit (16384 cpr) gear output sensing encoder has been integrated.

Harmonic Drive noted it has incorporated more features and capabilities into this actuator while maintaining a compact size and low mass. The RSF-5B-IDT Miniature actuator with an integrated servo drive is one of the latest products developed at Harmonic Drive LLC in Massachusetts, USA. The RSF joins the recently released family of FHA-Mini integrated actuators.
