Compact Zero Backlash Actuator with Integrated Servo Drive
New Actuator with Integrated Servo Drive from Harmonic Drive
Beverly, MA, April 30, 2021--- Harmonic Drive LLC, the leader in high precision motion control adds a new compact actuator with an integrated servo drive to its product portfolio. The RSA-8 with an integrated drive does not require a separate external servo drive which greatly simplifies cabling and reduces cabinet space requirements.
Featuring a CSF-1U-CC compact, zero-backlash gearhead, the RSA-8A integrated actuator provides high torque, exceptional accuracy and repeatability. The compact shape and low mass make it ideal for use in robotics. The RSA-IDT Actuator fits between the latest products released, RSF-IDT and FHA-IDT actuators, both in terms of size and specifications. This new actuator perfectly augments Harmonic Drive’s growing line of integrated actuators. Like all of the Integrated Actuators from Harmonic Drive LLC, it communicates via CANopen, and only requires 4 conductors: CANH, CANL, +24VDC, 0VDC. A single-turn 14bit (16384 cpr) gear output sensing encoder has been integrated.
- Actuator + Integrated Servo Drive utilizing CANopen communication conforming to DS402 and DS301
- 24VDC Nominal +7 to 30VDC Supply Voltage Range
- Single Axis BLDC Motor Controller/Driver with CAN & TTL-UART Interface
- Field Oriented Control
- Single Cable with only 4 conductors needed: CANH, CANL, +24VDC, 0VDC
- Zero Backlash
- Shaft or Flange output available
- Pigtail Connectors with 4 exit options
- 14bit (16384 cpr) resolution motor encoder
- Control Modes Including Torque, Velocity, and Position Control, CSP, CSV, CST
- Harmonic Drive HDL Software for initial tuning, commissioning, and analysis
- Homing modes include: single-ended, double-ended, double-ended with 16bit autoscale hardstop homing or teachable position
The RSA-8A-IDT Miniature actuator with an integrated servo drive is one of the latest products developed by our USA-based engineering group at Harmonic Drive LLC in Massachusetts. The RSA joins the recently released family of FHA-Mini integrated actuators.
