Product Description:

The R33GENC-R2-NS-VS-00 from Pacific Scientific is a member of the R Servomotors series. This compact motor unit is aimed at closed-loop positioning and velocity tasks in automated machinery. With its English mounting interface, it drops into legacy layouts, and its frameless resolver supplies analog position data to digital drives. This arrangement supports repeatable motion on compact axes that need steady response during position and speed changes. As a device for industrial automation, the R33GENC-R2-NS-VS-00 converts controlled electrical power into regulated mechanical shaft motion for pick-and-place heads, indexing tables, and similar motion axes.

At standstill, the motor can deliver a continuous shaft torque of 2.5 Nm, allowing it to hold moderate loads without overheating. During rated operation, it reaches 3000 rpm, a speed that matches typical ball-screw and belt stages driven by 50/60 Hz servo inverters. The rotor’s reflected mass is only 0.093 × 10⁻³ kg·m², which keeps the rotating assembly light for responsive motion. A 3.25-inch square frame simplifies mounting to NEMA 34 gearboxes and eliminates adapter plates. Its compact footprint also suits machines where surrounding hardware leaves little room for oversized motor bodies.

When rapid transients occur, the stator can generate up to 6.54 Nm of peak torque, supplying short bursts of force for indexing or overcoming breakaway friction. That capability is supported by rare-earth magnets, and the rotor uses samarium cobalt material that maintains magnetic strength at elevated temperatures. A Viton shaft seal protects internal bearings from coolant splash and airborne particulates encountered on packaging or machining lines. The laminated iron core is built to a 3-inch stack length, and the external C-style housing provides the required airflow clearance around the windings. Because the unit is supplied without a holding brake, holding torque must be provided by the drive or an external locking device when power is removed. The motor uses standard windings and does not include secondary feedback.
