R46GSNA-R2-NS-NV-04 by Pacific Scientific

The Pacific Scientific R46GSNA-R2-NS-NV-04 is a high-performance member of the R Servomotors series, designed for precision motion control in industrial automation. This programmable brushless servo motor delivers a continuous stall torque of 64 lb-in (7.2 Nm) and a peak torque of 270 lb-in (30.5 Nm), offering reliable power for demanding applications. With a thermal resistance of 0.52 °C/Watt, the R46GSNA-R2-NS-NV-04 efficiently dissipates heat during sustained operation. Its primary function is to provide smooth, accurate positioning and speed regulation in automated machinery and robotics systems.

Delving into technical specifications, this servomotor operates at a continuous stall current of 6.7 A and draws up to 53 A at peak torque, ensuring rapid response under varying loads. The motor’s torque constant is 10.8 lb-in/A (1.22 Nm/A) and its voltage constant is 128 V/Krpm (1.22 V/rad/sec), reflecting efficient energy conversion and precise control. Line-line resistance measures 3.2 Ohms when cold and 4.8 Ohms when hot, while the inductance of 20 mH balances dynamic responsiveness against electrical stability. Unique features include a low static friction of 0.39 lb-in (0.044 Nm) for reduced cogging effects and a viscous damping coefficient of 0.17 lb-in/Krpm (0.019 Nm/Krpm) for smooth motion at varying speeds.

Built to last, the R46GSNA-R2-NS-NV-04 weighs 25 lbs (11.3 kg) and features a compact inertia of 0.0034 lb-in·sec² (0.38 x 10^-3 kg·m²), facilitating easier load matching and system integration. Its brushless construction and high-quality bearings minimize maintenance requirements, enhancing uptime and operational efficiency. The motor is CE Approved, confirming compliance with safety and quality standards for industrial use. In industrial environments, users benefit from consistent performance, long-term durability, and compatibility with automation platforms, making this servomotor an ideal choice for precision-driven applications.
