Product Description:

The R32SSNA-R2-NS-NV-10 is manufactured by Pacific Scientific and belongs to the R Servomotors series. In automated lines, this motor supplies closed-loop rotary motion for positioning slides, feeders, and small transfer devices where compact size and repeatable torque are required. Its square frame eases mounting to gearheads or direct-drive couplings, allowing the motor to integrate with standard NEMA or metric machine interfaces without adapters.

The motor develops a continuous stall torque of 1.7 Nm, giving machinery the ability to hold static loads without hunting. During rapid acceleration or brief load spikes, it can reach 4.40 Nm, which is the peak value the drive amplifier must support for short overloads. Rotor inertia is limited to 0.071 kg·m² ×10⁻³, and this low mass helps the axis follow high-bandwidth velocity commands while keeping overshoot minimal. A 3.25" square frame footprint helps conserve mounting space and maintain clearance in multi-axis clusters. Torque is generated by rare-earth samarium cobalt magnets, a material with high residual flux density that supports stable motor constants over a wide temperature range.

The unit is factory-configured with no brake, so mechanical holding must be handled by the drive or by external clamps when the system is powered down. Position feedback comes from a frameless size 21 resolver, which provides rotor angle information over a full revolution without incremental counting. Because there is no shaft seal, the motor is best installed in clean, dry enclosures when washdown or airborne coolant may be present. With a laminated stack that measures 2 inches in axial length and a standard cylindrical housing, the motor remains lightweight and stiff. The design also omits secondary feedback devices, which helps keep wiring simple and avoids the need for additional drive feedback channels.
