Product Description:

The R65GENA-TS-SS-NV-02 is a brushless servo motor manufactured by Pacific Scientific for the R Servomotors series. In closed-loop motion systems, it supplies controlled torque and speed so that pick-and-place arms, indexing tables, or conveyor sections follow commanded profiles within a few encoder counts. The motor couples directly to a drive amplifier and external reducer, providing the electromechanical interface required for industrial automation tasks that repeat movement with high accuracy and short cycle times. This arrangement suits axes that need repeatable starts, stops, and speed changes during normal production.

At stall, the windings can deliver a continuous torque of 13.6 Nm without exceeding rated temperature, and the motor can reach a peak torque of 33.3 Nm during short acceleration or indexing moves. The nominal speed is 2000 rpm, and a properly sized drive can maintain stable velocity up to that point. A 5.75-inch square flange aligns with NEMA 23/34 hole patterns for direct coupling to gearheads or mounting plates. Dynamic response is supported by a rotor inertia of 1.26 kg·m² × 10⁻³, which helps the motor reverse quickly while resisting small load disturbances. The standard housing dissipates heat by natural convection, avoids the need for an auxiliary fan, and fits within compact electrical cabinets.

The stack length is 5 inches, giving the motor an overall depth that remains compact while enclosing the standard winding set. High-energy magnets made from rare earth samarium cobalt increase flux density, allowing the motor to produce rated torque from a compact frame. Position and velocity are reported through the factory-installed Tachsyn package, so a separate encoder channel is unnecessary. The motor uses an English mounting interface, and it comes without a holding brake or shaft seal. If the axis must remain fixed at standstill, holding torque must be supplied by the drive or by a separate mechanical device.
