Product Description:
The R67AMNH-R2-NS-NV-00 is a brushless AC servo motor produced by Pacific Scientific within the R Servomotors series. Designed for industrial automation axes that demand precise speed and position control, this motor interfaces with digital drives to move indexing tables, gantry heads, and packaging machinery. Its design emphasizes thermal efficiency and effective magnetic utilization, enabling reliable duty cycles in continuous production environments while keeping the motor footprint moderate.
It supplies a continuous stall torque of 19.9 Nm, allowing the axis to hold or move loads steadily without thermal overload. During short acceleration bursts, the electromagnetic stack can reach a peak torque of 48.9 Nm, providing additional capacity for rapid starts or overcoming inertia from attached tooling. Rotor momentum is limited by an inertia of 1.72 × 10-3 kg·m², which supports fast servo response by reducing overshoot during changes in speed or position. The motor has a 5.75-inch-square frame that provides a stable mounting surface for compatible gearboxes and machine flanges. Its laminated core has a 7-inch stack length, contributing to the available torque without increasing the frame’s cross section.
The motor employs rare-earth samarium-cobalt magnets that maintain magnetic flux across a wide temperature range. Position feedback is provided by a size 21 frameless resolver, which supports accurate commutation without adding unnecessary length to the housing. A metric mounting pattern simplifies integration with compatible machine frames and mounting hardware. The motor has no shaft seal, so it is best suited to installations where the shaft opening is not exposed to contaminants or fluids. Eliminating the seal also removes a friction-producing wear component from the shaft assembly while preserving the motor’s compact configuration.
