Product Description:
The Pacific Scientific’s manufactured R43-HSNA-TS-EF-NV-02 is a servo motor, capable of achieving a continuous stall torque of 3.7 Nm, which is ideal for applications requiring constant torque at zero speed. This servo motor uses a rare-earth samarium-cobalt magnet that is capable of exhibiting high magnetic qualities and sustaining torque uniformity during extended periods of operation.
The R43-HSNA-TS-EF-NV-02 motor is complemented by a continuous stall current of 6.9 A, so it can run continuously without heat stress under load. The torque constant (line-line) of this servo motor is 0.61 Nm/A, which allows for effective torque production per unit of current. The thermal control of this servo motor is provided by a thermal resistance of 0.72 °C/Watt and a thermal time constant of 19 minutes. Its class H insulation also provides additional thermal resistance, which safeguards this motor’s windings at high temperatures and guarantees long service life. The electrical features of this servo motor comprise a 2.5-ohm cold line-to-line resistance to guarantee smooth current supply at start-up. The line-to-line inductance of this motor is specified at 13.3 mH to assure smooth current transition and less electrical noise.
The feedback of this motor is governed by a Tachsyn sensor, which provides precise speed and position information to the control system. This also improves the response of this servomotor and holds accuracy in automated processes. The shaft diameter of the R43-HSNA-TS-EF-NV-02 servo motor is 19 mm, which makes it ideal for robust mechanical coupling with industrial machinery. This motor’s inertia measures 0.20 kgm² x10⁻³, and enables fast acceleration and deceleration with minimal overshoot. This servo motor also has a viscous damping coefficient of 0.011 Nm/Krpm to minimize vibration and enhance stability during changes in speed.
Frequently Asked Questions about R43-HSNA-TS-EF-NV-02:
Q: How does the Tachsyn feedback enhance motor accuracy in R43-HSNA-TS-EF-NV-02?
A: Tachsyn feedback provides reliable positional and velocity data. This ensures tight servo loop control and consistent motion output.
Q: Why is the samarium cobalt magnet used in this servomotor?
A: Samarium cobalt magnets offer high magnetic strength and thermal stability. This allows the motor to perform efficiently in high-temperature or demanding environments.
Q: How does the thermal time constant of 19 minutes benefit long operations?
A: A longer thermal time constant allows gradual heat accumulation. This helps in maintaining safe motor temperatures during extended duty cycles.
Q: What impact does a 0.011 Nm/Krpm damping coefficient have on motion stability?
A: It helps suppress oscillations during high-speed transitions. This enhances motion smoothness and minimizes mechanical stress.
Q: Why is Class H insulation critical for the R43-HSNA-TS-EF-NV-02 motor?
A: Class H insulation supports operation up to 180°C. It protects windings under high thermal loads and extends motor longevity.
