Product Description:

Pacific Scientific manufactures the R63GENA-TS-NS-VS-00 as part of its R Servomotors series. It is a servo motor for closed-loop motion systems, where commanded current from a matched amplifier is converted into controlled rotary movement. The unit is suited for indexing tables, pick-and-place heads, and material-handling axes that need accurate positioning, fast response, and stable torque during repeated cycles. In this type of application, the drive continuously corrects current based on feedback so the motor can track commanded speed and position with repeatable accuracy. Its form factor supports installation in automated equipment where dependable servo performance is required throughout normal production duty.

The motor provides a continuous stall torque of 8.3 Nm, which allows it to hold a load at zero speed while energized. For short acceleration demands, it can reach 20.5 Nm of peak torque to support quick indexing and speed changes. Nominal operation occurs at 3400 rpm, which suits many standard servo drive combinations. A rotor inertia of 0.81 × 10⁻³ kg·m² helps the axis respond quickly with controlled speed transitions. The square frame measures 5.75 in. on each side, and a 3-inch lamination stack fits within the housing. Rare-earth samarium-cobalt magnets support high flux density, and the standard winding supports stable thermal behavior during continuous operation. This balance of torque, speed, and inertia makes the motor appropriate for axes that alternate between holding, accelerating, and settling.

Machine builders mount the unit with an English flange pattern that matches inch-based pilot dimensions. Because it is supplied with no brake, stopping and holding functions must be provided by the drive or by external mechanical hardware. Rotor speed and position information are produced by a Tachsyn transducer, which combines tachometer and resolver functions in one device. There is no secondary feedback device installed, which reduces connector count and simplifies cable routing in compact machine layouts. The feedback arrangement keeps the interface simple when only the primary transducer is needed for control.
