Product Description:

The R67HEN-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific and belongs to the R Servomotors series. In automated production equipment, this motor receives command signals from a servo drive and translates them into precise shaft rotation that positions tooling, feeders, or conveyors at set speeds and angles. By supplying closed-loop torque and velocity control, the unit helps maintain repeatability in pick-and-place systems, labeling stations, and other motion axes that operate continuously during industrial duty cycles. This type of motor is well suited for applications that require accurate starts, stops, and speed changes throughout repeated machine motion.

The motor develops a continuous stall torque of 19.9 Nm, so it can hold a load at rest without overheating while feedback loops remain active. During rapid indexing, the electromagnetic package supports a peak torque of 48.9 Nm, giving extra headroom for acceleration before dropping back to its rated region. At a commanded velocity of 3000 rpm, the winding produces nominal power while keeping flux density within thermal limits. Rotor inertia is held to 1.72 × 10⁻³ kg·m², which helps shorten settling time by reducing overshoot during start-stop sequences. The square frame that measures 5.75″ on each side sets the mechanical envelope and matches standard mounting flanges on mid-sized gear reducers.

With a stack length of 7 inches, the rotor and stator generate the required flux within a compact axial profile, helping keep overall weight manageable for the English mounting pattern used on this model. The magnetic circuit relies on rare earth samarium cobalt segments, elevating torque density and allowing the high-speed winding to sustain current during extended high-rpm duty. Because the unit is delivered with no brake, external holding methods are required for vertical or safety-critical axes. The absence of brake hardware also eliminates residual drag and improves dynamic responsiveness when the motor reverses direction.
