Product Description:

The R24SSNA-R1-NS-NV-07 is a servo motor built by Pacific Scientific as a member of the R Servomotors series. With its compact housing, it is intended for direct coupling to gear trains or load shafts in industrial automation. The motor supplies controllable torque to position or regulate mechanical elements when driven by a compatible amplifier and feedback loop. When integrated with a motion controller, it converts electrical input into precise rotary motion for assembly machinery, material handling equipment, and other automated stations that require repeatable axis performance. This operating role makes it suitable for axes that must start, stop, and reverse with predictable response under varying loads.

The motor has a continuous stall torque of 1.1 Nm, which is the maximum torque the rotor can sustain indefinitely without overheating, and a peak torque of 3.07 Nm for short acceleration bursts. Its housing has a 2.0-inch outer diameter with a round profile, allowing installation where square-frame motors cannot fit, and it uses a standard housing style for straightforward flange mounting. Motion responsiveness is influenced by an inertia of 0.021×10⁻³ kg·m², which supports close load matching in dynamic applications. Low rotor inertia also helps the drive respond quickly to command changes during indexing and short-cycle positioning. Torque is produced by a rare-earth samarium cobalt magnet set that increases flux density and supports high torque density from the same stack length.

Position information returns to the drive through a size 15 frameless resolver, and no secondary transducer is fitted. Resolver feedback supports rotor angle tracking across a broad speed range and remains suitable for electrically noisy industrial environments. Because the motor is supplied with no holding brake, holding force must be provided by external clamping or drive torque when power is off. The motor has no shaft seal, so the installation should avoid fluid spray or positive-pressure washdown. A lamination stack length of 4 inches provides the active iron volume that supports the published torque ratings without increasing the overall envelope.
