Product Description:
The R46HSNA-TS-MN-VS-02 Servo Motor is designed and manufactured by Pacific Scientific, and its 40 mm shaft length provides secure coupling with mechanical assemblies and accommodates precise alignment in motion systems. This servo motor weighs 11.3 kg to enable a stable installation without weakening the structure.
This motor features a Viton shaft seal to offer chemical resistance and protection from oil or dust contamination, thus making it more durable in harsh conditions and extending its service life. This servo motor features an uncommon earth-samarium-cobalt magnet, which provides high torque performance without a decrease in magnetic efficiency even at high temperatures. The maximum torque output of this motor is rated at 30.5 Nm to accommodate high-load applications with fast response times. The R46HSNA-TS-MN-VS-02 motor generates this torque level at a maximum current consumption of 106 A, appropriate for dynamic and high-acceleration processes. The maximum value of this motor’s static friction is 0.044 Nm for providing a smooth start and minimal energy loss at rest-to-motion states. Similarly, this servo motor has a voltage constant (line-line) of 0.61 V/rad/sec to provide a consistent speed response under different voltage inputs. Its hot resistance line-to-line is 1.4 Ohms for providing effective current flow with minimal resistive heating.
This motor’s precise feedback is handled by a Tachsyn system for accurate rotor position and speed signals, which prevents instability in closed-loop operations where response accuracy matters. The thermal protection of this servo motor is facilitated by a thermal resistance of 0.52 °C/Watt, which efficiently dissipates heat produced and maintains inner temperature stability. This motor’s viscous damping coefficient is 0.019 Nm/Krpm to eliminate oscillations and improve motion smoothness on high-speed cycles. The altitude of installation of the R46HSNA-TS-MN-VS-02 ranges between 0 and 1000 meters above sea level, making it suitable for installation in normal industrial environments.
Frequently Asked Questions about R46HSNA-TS-MN-VS-02:
Q: Why is a Viton shaft seal used in this motor?
A: The Viton seal provides excellent resistance to chemicals and high temperatures. It helps prevent oil, dust, and moisture from entering the motor housing.
Q: What advantage does the samarium cobalt magnet offer in the R46HSNA-TS-MN-VS-02?
A: It retains magnetic strength at high temperatures and resists demagnetization. This ensures stable torque performance during extended duty cycles.
Q: How does the Tachsyn feedback in R46HSNA-TS-MN-VS-02 improve control accuracy?
A: Tachsyn provides analog feedback for both position and speed. This supports precise motor control in closed-loop systems.
Q: Why is the voltage constant important in a servomotor like R46HSNA-TS-MN-VS-02?
A: The voltage constant determines how the motor translates input voltage to rotational speed. A 0.61 V/rad/sec constant allows efficient and predictable speed control.
Q: What is the benefit of having a 0.044 Nm static friction value?
A: Low static friction reduces the effort needed to initiate movement. This helps in applications requiring high responsiveness at low speeds.
