Frequently Asked Questions about R2AA08075FXH03:

Q: How does rotor inertia affect performance in R2AA08075FXH03?

A: Lower rotor inertia (1.82×10⁻⁴ kg·m²) allows the R2AA08075FXH03 to rapidly respond to speed or position changes, improving control accuracy.

Q: Why choose an IP65 rated motor like R2AA08075FXH03?

A: The IP65 protection on R2AA08075FXH03 ensures resilience against dust and water ingress, enhancing reliability in harsh industrial environments.

Q: How does voltage constant affect motor performance in R2AA08075FXH03?

A: The voltage constant (19.5 mV per phase) in R2AA08075FXH03 contributes to stable and predictable motor behavior during operation.

Q: What is the recommended installation height for this R2AA08075FXH03 AC servo motor?

A: The motor is recommended to be installed under 1000 meters above sea level (without reduction in rated data). However, with the further increase in altitude the motor's efficiency will reduce gradually.

Q: What advantages does phase resistance offer in AC servo motors?

A: Low phase resistance (0.4 Ω in R2AA08075FXH03) minimizes power losses during motor operation, enhancing energy efficiency and reducing thermal generation.
