Product Description:
The R86GEBA-R2-NS-VS-00 servo motor is produced by Pacific Scientific for the R Servomotors series. It delivers controlled rotary motion to automated equipment such as pick-and-place arms, conveyors, and packaging stations. As a closed-loop actuator, it converts electrical input into mechanical output while returning shaft position to the drive, enabling accurate speed and torque regulation in industrial automation lines. Its performance characteristics suit mid-power axes that require quick reversals without excessive overshoot.
Under continuous load, the shaft can sustain 32.7 Nm of torque at zero speed, and this continuous-stall figure is the working limit for holding or low-speed indexing. During acceleration, the electromagnetic system supplies up to 66.6 Nm of peak torque for brief overloads. A nominal velocity of 2500 rpm supports direct coupling to moderate-speed machinery. The rotor inertia of 6.57 kg·m²×10⁻³ balances fast dynamic response against controller stability. Position data is provided by a frameless resolver in size-21 format, which transmits sine and cosine reference signals to the drive. Mechanical integration follows the English mounting pattern. The 6-inch stack length fits common machine layouts, and both the winding and housing style are standard.
A built-in 100 V DC brake locks the rotor when power is removed, which helps hold vertical loads. The frame is 7.5-inch square, matching common equipment footprints and improving surface heat dissipation. A Viton shaft seal shields internal bearings from dust, coolant, or washdown fluids. Torque density is enhanced by magnets made from samarium cobalt, a rare-earth alloy with high thermal stability. The design omits secondary feedback, reducing cabling and keeping the system architecture simple.
