Product Description:

The R67GENA-R2-NS-NV-00 is a Pacific Scientific’s high-power servo motor, which has a rated continuous stall current of 13.8 A to ensure durable operation in extended torque situations. This motor also runs with a maximum current of 82 A to support high-torque applications during acceleration.

This servo motor has a 24 mm shaft diameter and 50 mm shaft length for safe coupling with other mechanical parts and to limit the possibilities of misalignment during loading. The weight of this servo motor itself is 22 kg, which provides it with the necessary structural mass for vibration tolerance during high-speed operations. The torque constant (line-line) of 1.56 Nm/A makes this servo motor suitable for applications where precise movement is vital due to the reliability of force output per unit current. Another significant value of this motor is its 1.69 x 10 -3 kgm2 inertia, which serves to guarantee gradual acceleration and braking, especially in precision automation systems. This motor possesses a viscous damping coefficient of 0.104 Nm/Krpm, thereby lowering torque ripple and oscillation to a minimum; hence, smoothness is realized during dynamic variations in speed. This motor’s TENV, NEMA-approved, and IP65-rated housing construction guarantees ruggedness in its resistance to dust entry and exposure to low-pressure water. Internally, the R67GENA-R2-NS-NV-00 servo motor employs a rare-earth samarium-cobalt magnet, chosen for its performance at high temperatures, which ensures it operates consistently without decay.

The line-to-line inductance of this motor is 18.2 mH, and this aids voltage regulation and increases motor stability against sudden current change. The thermal time constant of the R67GENA-R2-NS-NV-00 motor is 72 minutes, which allows it to take up and release heat slowly while in sustained usage. The thermal resistance level is also 0.30 °C/Watt, which keeps this motor’s temperatures under control even during steady load.

Frequently Asked Questions about R67GENA-R2-NS-NV-00:

Q: How does the rare earth samarium cobalt magnet benefit the motor?

A: It maintains magnetic strength at high temperatures. This helps the motor deliver consistent torque under thermal stress.

Q: Why is the 0.104 Nm/Krpm viscous damping coefficient important?

A: It reduces oscillations and enhances speed stability. This results in smoother motor performance during dynamic operations.

Q: What role does the 72-minute thermal time constant play in the R67GENA-R2-NS-NV-00?

A: It allows extended heat absorption before reaching critical temperatures. This helps maintain motor efficiency during long duty cycles.

Q: How does the IP65 rating improve motor reliability?

A: It protects against dust and low-pressure water exposure. This increases lifespan in outdoor or industrial environments.

Q: Why is high inductance (18.2 mH) used in this motor?

A: It helps control current spikes during switching. This reduces electrical noise and improves overall drive performance.
