Product Description:

The R46GSNA-HS-SS-VS-01 is a brushless servo motor manufactured by Pacific Scientific. It is engineered for accurate motion control in industrial automation settings. The motor provides a continuous stall torque of 7.2 Nm. It can reach up to 30.5 Nm of peak torque. The rotor moment of inertia is rated at 0.0034 lb-in·s².

The static friction of the < is 0.39 lb-in. It has a viscous damping measured at 0.17 0.019 Nm/Krpm. The motor has a heat resistance of 0.52 °C/W. Its heat transfer time constant is 35 minutes. It weighs 11.3 kg to make it suitable for fixed mounting applications. It has a torque constant of 1.22 Nm/A and a voltage constant of 128 V/Krpm. It operates at a continuous stall current of 6.7 A and can sustain a peak current of 53 A. The cold resistance (line-to-line) is 3.7 Ohms. The R46GSNA-HS-SS-VS-01 servo motor has an inductance across the phases of 25 mH. It supports a stable current flow and reduced ripple during load changes. The resistance increases to 5.6 Ohms at elevated temperature. The R46GSNA-HS-SS-VS-01 is housed in a Totally Enclosed Non-Ventilated (TENV) enclosure. This offers full external protection without forced airflow. The motor includes a Viton shaft seal. It allows the motor to meet the IP65 protection level. It guards against dust and low-pressure water jets.

The R46GSNA-HS-SS-VS-01 servo motor meets NEMA enclosure standards for industrial use. Class H insulation allows operation in high-temperature environments. The motor also features a built-in PTC thermistor for thermal monitoring and safety shutoff under overheating conditions. The motor is UL Recognized under E103510 and E61960, confirming its compliance. Sealed bearings and the absence of brushes reduce maintenance needs over time. The brushless construction eliminates arcing and reduces electromagnetic interference.

Frequently Asked Questions about R46GSNA-HS-SS-VS-01:

Q: How does the brushless design of the R46GSNA-HS-SS-VS-01 motor benefit industrial applications?

A: The brushless design of the R46GSNA-HS-SS-VS-01 motor eliminates arcing, reduces electromagnetic interference, and minimizes maintenance needs. This ensures reliable, long-term operation in demanding industrial environments.

Q: Why is the heat transfer time constant of 35 minutes important for the R46GSNA-HS-SS-VS-01 motor?

A: The 35-minute heat transfer time constant of the R46GSNA-HS-SS-VS-01 motor ensures stable temperature regulation. This prevents overheating and maintains performance during extended operational periods under heavy load.

Q: How does the Viton shaft seal enhance the R46GSNA-HS-SS-VS-01 motor's durability?

A: The Viton shaft seal in the R46GSNA-HS-SS-VS-01 motor meets the IP65 protection level, preventing dust and water ingress. This improves the motor's resistance to harsh environmental conditions, ensuring longevity in industrial use.

Q: What role does the PTC thermistor play in the R46GSNA-HS-SS-VS-01 motor?

A: The PTC thermistor in the R46GSNA-HS-SS-VS-01 motor provides thermal monitoring, offering a safety shutoff function. This prevents overheating, safeguarding the motor during high-load operations and ensuring operational safety.

Q: Why is the R46GSNA-HS-SS-VS-01 motor's static friction of 0.39 lb-in significant?

A: The low static friction of 0.39 lb-in in the R46GSNA-HS-SS-VS-01 motor minimizes resistance to motion at rest, enabling smoother starts and reducing wear on components. This enhances precision and longevity in motion control applications.
