Product Description:
The R24HSNA-HS-NS-NV-03 servomotor from Pacific Scientific’s R Series is designed to provide both high torque and speed. It incorporates samarium cobalt rare earth magnets to offer superior torque-to-inertia ratio and it is equipped with Hall sensors as a primary feedback system to provide accurate position control in a variety of systems.
The R24HSNA-HS-NS-NV-03 servo motor delivers a continuous stall torque of up to 1.04 Nm and a peak torque of 11.3 Nm. It functions over a wide speed range and it can perform up to a top speed of 18000 RPM to fulfil the performance needs of high-speed applications. This motor does not include a secondary feedback system but an off-board additional system can be installed, depending on the requirement and it operates without a shaft seal, to have a reduced static friction of 0.35 Nm. It is built with long-life bearings, the front bearing is locked and the rear bearing is held by an O-ring, which enhances its durability and minimizes wear. The R24HSNA servo motor possess an angular inertia of 0.000018 kg·m², its viscous damping coefficient is at 0.0079 Nm/Krpm while its thermal impedance measures 1.14 °C/Watt. It takes 17 minutes to attain ambient temperature by dissipating heat through its provided aluminum heatsink of dimensions 10" x 10" x 1/4" and it offers protection ratings of IP65 to safeguard against dust and water.
The R24HSNA-HS-NS-NV-03 servo motor features class H insulation that makes it capable of withstanding high thermal environments and up to 155°C of winding temperature. It also includes overtemperature protective thermistors to ensure the motor does not overheat during operation. The R24HSNA servo motor comes enclosed in a 2” OD round frame and it weighs 1.5 kg. Its features and construction make it a perfect fit in robotics and linear actuators.
Frequently Asked Questions about R24HSNA-HS-NS-NV-03:
Q: How do samarium cobalt magnets improve the R24HSNA-HS-NS-NV-03 servomotor’s performance?
A: Samarium cobalt magnets provide a superior torque-to-inertia ratio, enabling quicker acceleration and more efficient torque output. They also resist demagnetization in high-temperature environments.
Q: Why does the R24HSNA-HS-NS-NV-03 use Hall sensors as the primary feedback?
A: Hall sensors offer reliable, contactless position feedback, ensuring precise motor control and reducing wear compared to mechanical encoders. This enhances system longevity and accuracy.
Q: What is the benefit of not having a shaft seal in the R24HSNA-HS-NS-NV-03?
A: Operating without a shaft seal reduces static friction to 0.35 Nm, allowing smoother startup and improved responsiveness. It also minimizes energy losses in low-speed operations.
Q: How do the front locked and rear O-ring-held bearings enhance durability in the R24HSNA servo motor?
A: This bearing arrangement minimizes axial play and protects against contaminants, reducing wear and prolonging the motor’s operational life under continuous use.
Q: What role does the aluminum heatsink play in the R24HSNA-HS-NS-NV-03’s thermal management?
A: The 10" x 10" x 1/4" aluminum heatsink efficiently dissipates heat, allowing the motor to reach ambient temperature in 17 minutes. This helps maintain optimal winding temperatures.
