Product Description:
The R46GSNA-SS-NS-VS-04 brushless servo motor is ideal for applications requiring precise control of motion. In controlled automation settings, the motor is designed by Pacific Scientific to consistently provide torque output and stable performance.
The max torque produced by the R46GSNA-SS-NS-VS-04 servo motor is 45 Nm, while the constant stall torque is 13 Nm. Its static friction behavior is defined by its 0.26 Nm cogging torque. Under current-controlled systems, the torque production can be accurately supported by a torque constant of 1.12 Nm per ampere. The back EMF behavior is linked to a voltage constant of 1.12 V per krpm. To facilitate the development of sustained torque, the continuous delay current is 13.1 A. For torque demands with shorter durations, the maximum peak current rating of 82 A is sufficient. The inertia of the rotor, which affects the dynamic response, is 1.24 kg·m². The velocity-based torque resistance is impacted by the viscous damping coefficient, which is 0.075 Nm per krpm. Applications requiring controlled speed and torque are well-suited to these parameters. When established electrical input circumstances necessitate constant mechanical reaction, the servo motor is an ideal component to incorporate into industrial automation systems. The application demands regulated torque characteristics and a consistent motion response, as determined by its design.
The thermal resistance of the R46GSNA-SS-NS-VS-04 servo motor is 0.42 °C per watt. It has a thermal time constant of 36 minutes, which shows how fast the motor gets to steady state when running continuously. Requirements for system cooling and operating duty cycles are intimately correlated with these thermal characteristics. The design allows for drive systems to work within the limitations of thermal regulation. Integrating load behavior and current feedback into multi-axis systems is made possible by this setup.
Frequently Asked Questions about R46GSNA-SS-NS-VS-04:
Q: Why does R46GSNA-SS-NS-VS-04 have a high inertia rating of 1.24 kg·m² in its design?
A: A high inertia rating stabilizes motor operation during rapid load changes. It helps maintain consistent rotational speed, enhancing positional accuracy and reducing vibration during dynamic movements.
Q: How does R46GSNA-SS-NS-VS-04 achieve consistent torque output using a torque constant of 1.12 Nm/A?
A: The torque constant of 1.12 Nm/A translates input current precisely into torque output. It ensures predictable torque control, essential for precise positioning and accurate motion sequencing operations.
Q: Why is the viscous damping coefficient of 0.075 Nm/Krpm important in R46GSNA-SS-NS-VS-04 motor operation?
A: A viscous damping coefficient of 0.075 Nm/Krpm provides controlled resistance against sudden speed variations. It smooths rotational movement, improving system stability and precision during acceleration or deceleration phases.
Q: Does R46GSNA-SS-NS-VS-04’s cogging torque of 0.26 Nm affect its precision motion capabilities negatively?
A: The cogging torque of 0.26 Nm is minimal and manageable. It does not significantly hinder precision movements, instead providing sufficient holding torque stability when the motor operates at low speeds.
Q: How does the thermal resistance of 0.42 °C/W in R46GSNA-SS-NS-VS-04 impact operational efficiency?
A: Thermal resistance of 0.42 °C/W defines the motor’s heat dissipation capacity. It ensures efficient thermal management, preventing overheating during sustained use, thus prolonging motor lifespan and operational reliability.
