Product Description:

The R32HENC-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific as part of the R Servomotors series. In automated equipment, it delivers closed-loop rotary motion, supplying controllable torque and speed to indexing tables, small gantry axes, and electronics assembly heads. Its compact square frame, resolver feedback, and standardized electrical interface let the unit pair with matched drives for precise position or velocity regulation in multi-axis machines.

The motor delivers a continuous stall torque of 1.7 Nm, while rapid start-stop cycles can draw on a peak torque of 4.40 Nm. The lightweight rotor has an inertia of 0.071 × 10⁻³ kg·m², so control loops can command high acceleration without excessive drive current. A rated speed of 7000 rpm supports direct coupling to fast pulleys or miniature spindles, which helps keep transmission ratios low and response time short. These capabilities are packaged inside a 3.25 inch square frame that reduces the footprint in compact enclosures and supports dense axis layouts on machine plates.

The motor uses a 2 inch stack length, which balances thermal dissipation against mass during continuous operation at high shaft speeds. Output is generated by rare earth samarium cobalt magnets, which maintain flux at elevated temperatures and reduce demagnetization risk. Rotor position is returned through a frameless resolver, an analog feedback device that tolerates electrical noise and high rotational speeds without requiring a secondary channel. Torque is produced by a high-speed winding optimized for the rated speed. The motor ships without an integral brake, uses a C housing style without a shaft seal, and mounts through English threaded holes, making it suitable for applications where load holding is handled externally and environmental protection is provided by the machine enclosure.
