R32GSBC-R2-NS-VS-02 by Pacific Scientific

The Pacific Scientific R32GSBC-R2-NS-VS-02 is a robust brushless servo motor from the R Servomotors series by Pacific Scientific. It offers a continuous stall torque of 14 lb-in and delivers an impressive peak torque of 66 lb-in, making it ideal for precise motion control in demanding industrial automation environments. This compact unit weighs just 5.5 lbs, facilitating simple integration into machinery and tight spaces.

Precision engineering defines the technical prowess of the R32GSBC-R2-NS-VS-02. Its line-to-line inductance of 23 mH and a torque constant of 4.4 lb-in/A ensure efficient power conversion at both low and high speeds. The motor’s thermal resistance of 0.93 °C/Watt and a thermal time constant of 20 minutes maintain stable operating temperatures under continuous load. Resistance values of 7.3 Ohms cold and 10.9 Ohms hot optimize current flow, while a viscous damping coefficient of 0.04 lb-in/Krpm reduces oscillations for smooth acceleration. Static friction is limited to 0.23 lb-in, minimizing drag and energy loss at start-up.

Beyond core performance, this servo motor stands out for its efficiency and durability. The low inertia of 0.00045 lb-in-sec² permits rapid acceleration and precise speed control, essential in high-throughput applications. A line-to-line voltage constant of 52 V/Krpm ensures consistent back-EMF characteristics at varied speeds. Designed for long service life, it handles a continuous stall current of 3.6 A with peak currents up to 32 A at maximum torque. Its lightweight construction and optimized thermal management enhance reliability in industrial settings. By combining high torque density, thermal stability, and compact form factor, the R32GSBC-R2-NS-VS-02 provides tangible productivity gains and reduced maintenance costs for automation systems.
