Product Description:
The R33HENC-R2-NS-NV-00 is a servo motor, which is engineered by Pacific Scientific with a torque constant rating of 2.4 Nm for consistent rotational force and predictable motion under prolonged duty cycles. Its weight of 3.2 kg makes it light yet still capable of maintaining adequate mechanical strength, even for assemblies that have limited space.
This R33HENC-R2-NS-NV-00 servo motor’s electrical parameters include a back EMF constant of 0.33 V/rad/sec, crucial for ensuring controlled braking and precise regeneration of voltage when it decelerates. This servo motor’s continuous current rating of 7.8 A allows continuous operation under load without overheating, ideal for longer-processing equipment or repetitive motion applications. Having a line-to-line resistance of 1.7 Ω, this servo motor reduces internal energy loss and effectively manages heat dissipation to provide a stable power supply to the motor windings. This motor operates on a bus voltage of 320 VDC and can integrate into standard DC systems to provide smooth acceleration and steady speed control. The 600 VDC maximum voltage rating broadens this motor's application scope to increased voltage environments, providing an additional level of protection and operational security.
The no-load speed of 6000 RPM prepares this servo motor for high-speed operation to enable quick reversals in rotational direction and velocity in applications requiring fast response rates. The output power of the R33HENC-R2-NS-NV-00 motor is rated at 0.71 kW to excel in medium-power applications like automated tooling, positioning equipment, and compact robot systems. The frameless resolver used for primary feedback of the R33HENC-R2-NS-NV-00 servo motor offers non-contact, absolute position sensing and improves motion control reliability by removing mechanical wear points. This motor falls under the class F insulation class, which promises maximum thermal resistance and long-term electrical insulation reliability despite intensive usage.
Frequently Asked Questions about R33HENC-R2-NS-NV-00:
Q: How does the frameless resolver improve feedback accuracy in this motor?
A: The frameless resolver provides direct rotor position feedback without contact, reducing mechanical wear. This ensures long-term precision in position sensing for motion control systems.
Q: Why is the insulation class F important in the R33HENC-R2-NS-NV-00?
A: Insulation class F allows operation at higher temperatures up to 155°C. This supports prolonged use in thermally demanding industrial environments.
Q: What is the advantage of having a 600 VDC maximum voltage rating?
A: It enables the motor to withstand voltage surges and operate safely in high-voltage systems. This improves reliability in industrial control environments with variable power conditions.
Q: How does the 1.7 Ω line-to-line resistance affect thermal efficiency?
A: Lower resistance reduces internal heat buildup and energy losses. It improves overall efficiency and minimizes the need for additional cooling systems.
Q: Why is a continuous current rating of 7.8 A beneficial in repetitive motion tasks?
A: It allows the motor to maintain torque without performance drop over repeated cycles. This is essential in applications like pick-and-place and conveyor systems.
