Product Description:

The R65GMNA-TS-LG-NV-00 is a brushless servo motor manufactured by Pacific Scientific within the R Servomotors series. Designed for closed-loop motion platforms, it supplies controlled rotary power to indexing tables, pick-and-place heads, and similar duty cycles in automated machinery. Closed-loop feedback allows the motor to respond quickly to changing load and position commands during repetitive automation cycles. It uses a factory-assigned winding and is supplied without an integrated holding brake or shaft seal, which helps keep the motor compact when external braking or sealing is provided elsewhere in the machine.

Continuous stall torque is rated at 13.6 Nm, which is the steady torque the motor can deliver at standstill without exceeding temperature rise limits. For short moves, the motor can generate up to 33.3 Nm of peak torque to support rapid acceleration or brief overloads. The rotor inertia is 1.26 kg·m² × 10⁻³, which supports responsive servo tuning and stable motion control. Nominal operation is rated for 2000 rpm, giving a broad usable speed range with standard R-series drives. The motor uses a compact 5.75" square frame with a standard housing style and a standard winding.

Magnetic excitation is provided by rare earth (samarium cobalt) magnets, which offer strong flux density and stable performance across a wide operating temperature range. The active laminate stack measures 5 inches in length, setting the motor's axial footprint and supporting the torque level of this frame. Rotor position and velocity feedback are generated by a Tachsyn transducer, allowing compatibility with controllers that use tachometer and resolver signals. This feedback arrangement is useful in systems that rely on analog velocity and position information instead of fully digital encoder protocols. Installation uses a Metric flange pattern for mounting on compatible machine faces.
