Product Description:

The R24HSNA-HS-NS-NV-03 is a servo motor produced by Pacific Scientific within the R Servomotors series. It serves as the electromechanical interface between an electronic drive and a machine axis, translating programmed current into precise rotational motion for pick-and-place heads, conveyors, or light machining spindles. Compact outer dimensions and a cylindrical housing let the unit fit into equipment where square-flange motors are impractical. Its high base speed also supports rapid throughput in compact automation systems.

Its continuous stall capability is 1.1 Nm, which is the maximum torque the motor can deliver indefinitely without exceeding thermal limits. For short acceleration bursts, it can reach 3.07 Nm of peak torque, adding margin for momentary overload conditions. The rated mechanical velocity is 7700 rpm, so appropriate gearing or direct-drive coupling can use that speed for high cycle frequencies. The motor has a round frame with a 2.0-inch outer diameter, which simplifies mounting into instrument-grade frames and compact enclosures, and the 4-inch stack length sets the active magnetic path that produces the listed torque. The housing follows a standard configuration, allowing convection or cabinet-fan airflow without special shrouds.

Dynamic response benefits from a rotor inertia of 0.021 kg·m² × 10⁻³, which helps keep commanded speed changes sharp and minimizes servo lag. Output density is increased by rare-earth samarium-cobalt magnets that withstand high internal temperatures without flux loss. Electrical commutation relies only on Hall sensors, and no secondary feedback element is installed, which streamlines wiring when basic position recognition is adequate. The high-speed winding aligns with the motor’s base velocity and permits full power delivery at moderate bus voltage. Because the motor ships without a holding brake and lacks a shaft seal, external clamping devices or environmental gasketing are required wherever static holding or fluid exclusion is critical.
