Product Description:

Pacific Scientific designs the R86GENA-R2-NS-NV-00 as a brushless servo motor in the R Servomotors series. The device converts electrical command signals into controlled mechanical rotation for tooling, conveyors, and indexing tables on automated lines. Integrated frameless resolver feedback allows the drive to monitor rotor angle directly, which supports stable velocity and torque control during changing load conditions. The motor uses a standard housing with English face mounting, so it can fit existing machine layouts and connect to couplings, belts, or gear reducers without unusual adapters.

At stall, the motor can deliver a continuous torque of 32.7 Nm, allowing it to hold load without overheating under proper cooling conditions. For rapid acceleration or short disturbance rejection, the electromagnetic system provides up to 66.6 Nm of peak torque for brief intervals. During normal motion, it operates at a rated speed of 2500 rpm, which supports sustained duty in typical servo applications. Dynamic response is influenced by a rotor inertia of 6.57 × 10⁻³ kg·m², helping the axis balance stability and responsiveness during reversals. The motor uses a 7.5 in square frame, which suits common mounting patterns and supports alignment with matching mechanical components.

Performance is supported by a magnet array made from rare earth (samarium cobalt), which provides strong magnetic flux and good stability across temperature changes. The motor is supplied with no brake, so any holding force after power removal must come from the drive or external mechanics. It also has no shaft seal, making it better suited to installations that are protected from direct liquid exposure. A stack length of 6 inches provides the active length needed for the winding and magnetic circuit. This layout helps the motor support its rated output while remaining within the package size used for this frame.
