Product Description:

Pacific Scientific manufactures the R33GEN0-R2-NS-NV-00 and assigns it to the R Servomotors series, a line of brushless rotary actuators. The unit is a servo motor intended to convert commanded current from a digital drive into accurately regulated angular position, velocity, and torque on light-duty industrial axes. By integrating into indexing tables, electronic cams, or vision-guided pick-and-place heads, it helps machine builders achieve repeatable motion profiles without mechanical gear backlash. Its brushless design also supports consistent response during repeated duty cycles without the wear associated with mechanical commutation.

The motor occupies a 3.25" square frame and a stack length of 3 inches, so it can fit into tight machine layouts that follow English mounting standards. A rotor inertia of 0.093 kg·m²×10⁻³ helps the axis respond quickly when direction changes are frequent, while the windings allow a rated speed of 3000 rpm for continuous production cycles. Continuous stall torque reaches 2.5 Nm, letting the shaft hold loads at zero speed without overheating. The English mounting pattern aligns with common hardware, and the standard winding option balances copper fill with thermal rise so the motor can deliver its nameplate performance from typical 320 VDC servo amplifiers.

Momentary load surges are supported by a peak capability of 6.54 Nm, giving the system extra headroom for rapid indexing or sudden deceleration. Rotor angle is reported by a frameless resolver, transmitter type, size 21, which supplies analog sine-cosine signals for high-resolution interpolation, and the design omits secondary feedback to reduce wiring complexity. Torque density is increased by using rare earth samarium cobalt magnets that maintain flux at elevated temperatures. Because the unit ships with no brake, holding force after power loss must be supplied externally, and the lack of a shaft seal limits use to clean, dry environments unless additional guarding is provided.
