Product Description:
The R86GEAA-R2-NS-NV-00 is a servo motor developed by Pacific Scientific for the R Servomotors series. As a rotary actuator, it converts drive current into controlled mechanical motion for coordinated positioning or velocity control in automated machinery and material-handling cells. The combination of electromagnetic torque production and built-in feedback makes this motor suitable for closed-loop operation with matched drives and controllers.
At stall, the motor can deliver 32.7 Nm continuously, providing a clear baseline for static load support under rated cooling. Its 7.5-inch square frame matches standard NEMA mounting patterns used in many industrial installations. A 24 V dc brake is integrated so the shaft can be held when power is removed, which is useful on vertical axes. Rotor inertia is 6.57 × 10⁻³ kg·m², which affects acceleration response when the motor is coupled to reflected load inertia. The motor can reach a peak output of 66.6 Nm during brief transients, permitting rapid indexing during short-duty events. Its rated base speed is 2500 rpm, which fits common gearbox ratios and drive voltage ranges. Primary motion feedback comes from a size 21 transmitter-type resolver, allowing the drive to monitor rotor position during operation.
A rare-earth magnetic circuit that uses samarium cobalt helps maintain flux density over temperature changes while keeping the motor compact. The stack length measures 6 inches, providing the active axial iron needed for the stated torque output without increasing motor width. Installation follows the English mounting convention, so bolt patterns and shaft geometry use inch-based dimensions. The housing style is standard for the series, and the motor has no shaft seal, so the machine must provide external protection against fluid ingress. No secondary feedback channel is fitted, and a standard winding works with the resolver interface for typical three-phase drive operation in this frame class.
