Product Description:
Pacific Scientific's R24HENA-HS-LB-NV-00 is a Brushless servo motor developed for precision motion control applications. It is part of the R Series, which features rare earth magnets and a 2-inch outer diameter with a 4-inch stack length, allowing for compact mounting arrangements. The motor is suited for a variety of industrial automation applications.
Under static loads, the R24HENA-HS-LB-NV-00 servo motor can maintain a constant torque supply because of its 9.2 lb-in continuous stall torque. A maximum torque of 100 lb-in allows it to manage brief periods of intense demand. Quick acceleration profiles are made possible by the motor's inertia, which is 0.160 × 10⁻³ lb-in·sec². The amount of torque needed for starting is impacted by the 0.31 lb-in of static friction. It impacts dynamic stability with its viscous damping coefficient of 0.07 lb-in./Krpm. One factor influencing heat dissipation is the thermal resistance, which is 1.14 °C/Watt. The rate of temperature change while it is operating is determined by its thermal time constant, which is 17 minutes. Type H is the designation for the winding configuration, which means it is compatible with certain driving systems. In order to help with commutation and speed control, the motor incorporates integrated Hall sensors that provide primary feedback. In order to supply closed-loop control systems with precise position data, a 1000 ppr encoder that has a line driver output serves as supplementary feedback.
The shaft of the R24HENA-HS-LB-NV-00 brushless servo motor is English-configured and lacks a shaft seal. The motor comes with optional 18-inch flying leads, which allow for flexible connection in small enclosures. Thermal and feedback standards ensure that the product performs consistently. It is designed primarily for industrial automation situations, where temperature management and motion feedback have a direct impact on control performance.
Frequently Asked Questions about R24HENA-HS-LB-NV-00:
Q: Why does the R24HENA-HS-LB-NV-00 motor include Hall sensors as primary feedback components?
A: Hall sensors provide essential commutation signals and detect rotor position. This supports precise control in brushless servo applications and enables efficient startup and directional tracking.
Q: Why is the viscous damping coefficient important in the R24HENA-HS-LB-NV-00 servo motor?
A: The 0.07 lb-in./Krpm damping minimizes oscillations. This improves system stability during speed changes and enhances motion smoothness during dynamic operations.
Q: How does the thermal time constant affect the R24HENA-HS-LB-NV-00 performance under sustained load?
A: The 17-minute thermal time constant slows temperature rise. This allows the motor to handle temporary overloads without immediate overheating or triggering thermal limits.
Q: Do the 1000 ppr encoder outputs in R24HENA-HS-LB-NV-00 enhance control accuracy?
A: Yes, the encoder with line driver output improves resolution and signal integrity. It supports high-precision motion control and closed-loop feedback applications.
Q: Why does the R24HENA-HS-LB-NV-00 lack a shaft seal in its design?
A: The absence of a shaft seal reduces friction and cost. It is intended for clean environments that do not require sealing against contaminants.
