Product Description:

The R63GENA-TS-NF-NV-00 servo motor is manufactured by Pacific Scientific and belongs to the R Servomotors series. As a brushless product type intended for closed-loop motion systems, it supplies commandable torque to position or regulate loads in assembly cells, pick-and-place gantries, and other automated equipment. The motor couples directly to a drive via English mounting provisions and is delivered in a standard housing that simplifies installation inside machinery where space, reliability, and repeatability are controlling factors. A factory-assigned configuration without an internal holding brake reduces length and inertia for applications that rely on external mechanical restraint.

Under steady thermal conditions, the motor can supply 8.3 Nm of continuous stall torque, a value available at zero speed for tight position control. During rapid acceleration, it tolerates load surges up to 20.5 Nm, allowing short duty peaks without exceeding thermal limits. The rated mechanical speed of 3400 rpm aligns with typical servo drive voltage bases and supports mid-range actuator velocities. Rotor inertia is kept to 0.81 kg·m² × 10⁻³, enabling fast response with minimal overshoot when the drive issues torque commands. Overall dimensions are set by a 5.75-inch square frame that matches legacy patterns. The design omits a shaft seal and uses standard windings.

A 3-inch stack length sets the active lamination depth and balances torque density with heat dissipation. The permanent-magnet rotor uses rare earth (samarium cobalt) material, increasing flux while resisting demagnetization at elevated temperatures. For velocity feedback, the motor integrates a Tachsyn resolver, supplying analog speed and position data to older control platforms, while a 1000 ppr line-driver encoder provides digital incremental signals for newer servo amplifiers. This dual feedback arrangement broadens drive compatibility, allowing integration into axes that demand responsive torque and precise positioning.
