Product Description:

The R33HENC-R2-NS-NV-00 servo motor is built by Pacific Scientific within the R Servomotors series. Designed for closed-loop motion axes in assembly, material handling, and packaging machinery, it converts drive current into controlled rotary displacement while reporting position back to the controller. The unit is intended for compact installations that need responsive torque, accurate shaft positioning, and repeatable motion during frequent starts, stops, and speed changes.

In continuous operation, the motor sustains a stall torque of 2.5 Nm, meaning it can hold static loads at that level without overheating during steady holding duty. For rapid indexing or start-stop sequences, it delivers a peak torque of 6.54 Nm, giving the drive additional headroom during acceleration and short overload events. Its base mechanical speed is 6000 rpm, a rating that suits processes requiring high shaft velocity, such as labelers or centrifugal pumps. Dynamic response is influenced by the rotor inertia of 0.093 kg·m²×10⁻³, which helps the motor accelerate quickly without requiring excessive drive current. Magnetic flux is produced by rare earth samarium cobalt magnets, which increase torque density while keeping the frame compact. The motor is supplied without a holding brake, uses English-pattern mounts, and has a C housing style.

The motor has a 3.25-inch square frame and a stack length of 3 inches, resulting in a short axial footprint that fits shallow machine bays and compact slide assemblies. Rotor position is returned through a frameless resolver transmitter in size 21, so the controller can commutate and track motion without an external encoder; there is no secondary feedback channel. The winding is classified as High Speed, allowing the stator to generate rated power at elevated frequency while maintaining thermal limits at higher operating speeds. Because the motor does not include a shaft seal, any external sealing must be provided by the surrounding machine enclosure.
