Product Description:

The R35KENP-R2-NS-NV-00 is a 3-phase permanent magnet brushless DC servo motor that is manufactured by Pacific Scientific. It is designed for applications requiring precise speed and torque control. The motor is designed for use in systems that demand reliable motion control. It is appropriate for integration into a variety of motion-based systems, including industrial automation platforms.

The R35KENP-R2-NS-NV-00 3-phase permanent magnet brushless DC servo motor produces 1.9 horsepower at a maximum speed of 6300 RPM and a rated speed of 5370 RPM. The rated torque is 27 lb-in, which is maintained at a current of 6.6 amps. The stall torque and current are rated at 27 lb-in and 6.0 amps, respectively. The voltage constant (Ke) of 56 V/kRPM enables accurate back EMF measurement. The motor has a resistance of 2.3 ohms, which helps regulate the current. The duty rating designation is F, which specifies the operational duration within specific heat ranges. The insulation class is F, which allows thermal durability up to 155°C. A shaft seal is included to create a mechanical barrier at the shaft entry location. The motor is UL-listed, which ensures compliance with proven safety standards. The shaft seal and thermal rating contribute to a longer operational life at rated loads.

The rated ambient temperature is 40°C, which determines the operational thermal environment. The motor is a permanent magnet brushless DC, which provides for precise torque delivery. These specifications make them suitable for use in automated positioning systems and servo drive assemblies. The R35KENP-R2-NS-NV-00 DC servo motor is suitable for industrial automation systems that require compact motion components. The motor's electrical setup and 3-phase architecture make it possible to achieve repeatable speed control. The motor is designed to ensure torque stability throughout prolonged operation.

Frequently Asked Questions about R35KENP-R2-NS-NV-00:

Q: How does R35KENP-R2-NS-NV-00 support rated stall torque?

A: R35KENP-R2-NS-NV-00 maintains 27 lb-in stall torque under 6.0 amps. This enables reliable torque performance during startup and low-speed operation without loss of control.

Q: Why is insulation class F used in R35KENP-R2-NS-NV-00?

A: Insulation class F supports thermal endurance up to 155°C. This increases operational life under rated ambient conditions and allows use in controlled environments.

Q: Does R35KENP-R2-NS-NV-00 include a shaft seal feature?

A: Yes, the shaft seal is included to provide mechanical protection at the shaft interface. It helps prevent debris or particles from entering the motor housing.

Q: Do the 3 phases in R35KENP-R2-NS-NV-00 improve performance?

A: The 3-phase configuration ensures smoother torque delivery and better efficiency. It enables accurate control in servo systems requiring consistent motion output.

Q: Why does R35KENP-R2-NS-NV-00 have a voltage constant of 56 V/kRPM?

A: The voltage constant enables accurate back EMF feedback for speed control. This helps optimize motor response in systems requiring precision regulation.
