R32GMNC-R2-NS-VS-02 by Pacific Scientific

The Pacific Scientific R32GMNC-R2-NS-VS-02 is a high-performance synchronous servo motor in the R Servomotors series, engineered for demanding industrial automation tasks. Its 4-pole construction with samarium cobalt permanent magnets delivers a robust continuous stall torque of 1.7 Nm and a peak torque of 4.40 Nm, ensuring precise control under varying loads. Designed for compatibility with a 240 V AC/320 V DC bus system, this servo motor integrates seamlessly into modern motion control architectures while providing a high torque-to-inertia ratio and demagnetization resistance. The compact form factor of the R32GMNC-R2-NS-VS-02 combines enhanced thermal performance and low rotor inertia, positioning it as a versatile solution for applications where rapid acceleration and accuracy are essential.

In terms of technical specifications, the R32GMNC-R2-NS-VS-02 achieves a torque constant of 0.6 Nm/ARMS and a voltage constant (RMS) of 0.36 V RMS/rad/sec, enabling consistent torque output across its speed range. The motor’s continuous stall current of 2.9 ARMS and current at peak torque of 8.7 ARMS are managed through a line-to-line resistance of 7.3 Ohms and an inductance of 23.0 mH, ensuring predictable electrical performance. Thermal management is optimized with a thermal resistance of 0.93 °C/Watt and a thermal time constant of 20 minutes, facilitating efficient heat dissipation under continuous operation. Additional electrical parameters include a power factor of 0.95, efficiency of 90%, and operation at 50 Hz, all powered at 220 V for versatile drive compatibility.

Operationally, this servo motor delivers a typical rated speed of 4,000 RPM and a typical rated torque of 1.2 Nm, supporting dynamic response for high-speed positioning tasks. The anti-cog stator design minimizes torque ripple, while a maximum static friction of 0.03 Nm and viscous damping coefficient of 0.005 Nm/kRPM reduce energy losses and improve smoothness. With a peak current capacity of 10 A and a peak torque current rating of 8.7 ARMS, the unit maintains stable performance even during rapid acceleration and deceleration cycles. Weighing just 2.5 kg, the R32GMNC-R2-NS-VS-02 presents a favorable power-to-weight ratio that simplifies mechanical integration and reduces bearing loads.

System integration is streamlined through compatibility with Pacific Scientific servo drives and standard AC/DC bus interfaces, allowing straightforward installation in both new and retrofitted systems. The robust electrical and thermal design supports continuous operation in industrial environments, while the high torque density suits applications in CNC machinery, robotics, packaging equipment, and precision assembly lines. As part of the Pacific Scientific R Servomotors series, the R32GMNC-R2-NS-VS-02 delivers reliable, high-precision motion control for a wide range of automation challenges.
