Product Description:
The R33GENT-TS-NS-NV-03 is produced by Pacific Scientific within the R Servomotors series. Built for closed-loop motion axes in packaging, material handling, and general automation, it converts drive current into precise rotary position and speed. The unit uses an English mounting pattern for direct substitution into systems that follow imperial layouts, and the shaft is supplied without a seal, so an external barrier is required where oil mist or coolant are present. Standard windings are fitted, allowing the motor to match standard drive ratings without custom coil data. Its construction supports continuous servo duty in positioning loops.
Its continuous stall capability of 2.5 Nm is the torque the rotor can sustain indefinitely without exceeding thermal limits. A compact 3.25 in. square frame allows the motor to fit in tight spaces while still dissipating heat through aluminum endbells. The reflected load can be sized to its rotor inertia of 0.093 × 10⁻³ kg·m², balancing quick acceleration with stable control. When rapid indexing is needed, the motor can deliver a peak of 6.54 Nm for short periods. Velocity regulation is based on a rated speed of 3000 rpm, which matches the operating range of typical digital drives.
Rare-earth magnets made from samarium cobalt raise torque density and improve resistance to thermal demagnetization, complementing the motor's Tachsyn primary feedback device that sends analog velocity and position signals to the controller. The laminated stack measures 3 inches in length, which sets the axial footprint and helps shape the continuous power curve. Because the unit has no brake, holding torque must come from the drive or an external brake if vertical loads are present. Secondary feedback is not provided, and the motor relies solely on the Tachsyn channel for loop closure.
