Its housing is protected with IP65 class and it can operate at ambient temperatures of up to 40°C without derating, while its withstanding capability is up to 60°C with derating.
Frequently Asked Questions about MS2N10-D0BNL-RSTB0-NNNNN-NN:
Q: What role does the five pole-pairs configuration play in MS2N10-D0BNL-RSTB0-NNNNN-NN’s torque delivery?
A: The five pole pairs increases the magnetic field interactions per revolution, improving torque smoothness. It also reduces torque ripple and improves control at lower speeds.
Q: How does the low moment of inertia (0.0081 kg·m²) improve MS2N10-D0BNL-RSTB0-NNNNN-NN’s performance?
A: It allows for faster acceleration and deceleration since less angular momentum needs changing. This enhances responsiveness in dynamic motion control applications.
Q: Why is liquid cooling used in MS2N10-D0BNL-RSTB0-NNNNN-NN instead of air cooling?
A: Liquid cooling efficiently removes heat from the motor’s windings and core under high load. It enables higher continuous power ratings without overheating in compact spaces.
Q: What does the IP-65 housing protection entail for MS2N10-D0BNL-RSTB0-NNNNN-NN’s usage environment?
A: The IP65 means it is dust tight and protected against water jets from any direction. This permits operation in industrial or dusty/wet environments without enclosure damage.
Q: Why is the EMF constant of 118.5 V/1000 RPM significant in control of MS2N10-D0BNL-RSTB0-NNNNN-NN?
A: That constant helps in designing the drive electronics and estimating back-EMF for speed control. It ensures matching to the inverter voltage and safe operation at high speeds.
