Product Description:

The R33GENC-R2-NS-VS-00 Servomotor of Pacific Scientific delivers precise motion control with a compact 3-inch width and peak torque of 98 lb-in. It comes with G type windings, draws 3.9 A current and has a single resolver based feedback system which makes it ideal for automation applications demanding efficiency and simplicity.

The R33GENC-R2-NS-VS-00 servo motor magnetic assembly stretches to a length of three inches and its shaft entry point is encased with a protective barrier made from Viton which is a durable and chemically resistant synthetic rubber. It incorporates a heat-sensitive resistor that increases its electrical resistance as temperature rises as this component functions as a thermal safeguard, limiting power or triggering a shutdown upon the detection of overheating. This module's external housing features a symmetrical square outline, with each side measuring 4.25 inches which facilitates uniform mounting and spatial fitting in a variety of machinery configurations. Its electrical interface uses military-standard circular connectors, known for their durability and secure locking mechanisms which ensure a reliable connection for signal and power lines, even in vibration-prone environments. Its rotor spins at a top speed of 3000 1/min which enables rapid and responsive motion control suitable for dynamic automation tasks or precision manufacturing equipment and it includes a resolver which accurately detects angular position and velocity.

This R33GENC-R2-NS-VS-00 servo motor employs rare-earth samarium cobalt magnets, known for their exceptional resistance to demagnetization and stability at high temperatures and its shaft diameter and bolt patterns inch based standards which ensures compatibility with North American or similarly specified hardware systems. Its casing is built to prevent intrusion of external elements as it follows Totally Enclosed Non-Ventilated (TENV) principles, adheres to National Electrical Manufacturers Association (NEMA) standards and meets the IP65 rating.

Frequently Asked Questions about R33GENC-R2-NS-VS-00:

Q: Why does the R33GENC-R2-NS-VS-00 use samarium cobalt magnets instead of neodymium?

A: Samarium cobalt magnets offer superior thermal stability and resistance to demagnetization. This makes the R33GENC-R2-NS-VS-00 ideal for high-temperature and harsh industrial environments.

Q: How does the resolver feedback in this servomotor enhance performance?

A: The frameless resolver provides precise position sensing with high reliability. It functions well in electrically noisy environments, improving motion control accuracy.

Q: What benefit does the Viton shaft seal offer in the R33GENC-R2-NS-VS-00 motor?

A: The Viton seal resists chemicals, oil, and high heat. This protects internal components, extending motor life in demanding conditions.

Q: Why is a PTC thermistor used for thermal protection in this servomotor?

A: A PTC thermistor passively increases resistance when overheated. This limits current flow and helps prevent motor damage due to temperature spikes.

Q: What advantage does the square 4.25" frame provide in this design?

A: A square frame allows consistent mounting from any side. It simplifies installation in space-constrained machinery.
