Product Description:

The R32GMNC-HS-MD-NV-00 is a brushless AC servo motor produced by Pacific Scientific for the R Servomotors series. It converts drive current from a matched amplifier into regulated rotary motion for indexing tables, packaging axes, and other automated stations that need precise positioning. Its compact housing supports use in tightly spaced machinery while maintaining the responsive control expected from a servo system. The motor is intended for applications that require repeatable starts, stops, and direction changes under closed-loop control.

The motor provides a continuous stall torque of 1.7 Nm, which allows stable holding and low-speed operation without excessive heat buildup. For short acceleration periods, it can reach a peak torque of 4.40 Nm, giving the axis additional force during brief demand changes. Its rated speed is 4000 rpm, supporting fast rotary motion in high-response servo applications. Dynamic behavior is supported by a reflected inertia of 0.071 kg·m² × 10⁻³, which helps the motor respond quickly to changing commands. Torque production relies on rare earth (samarium cobalt) magnets for strong magnetic flux in a compact package. Integrated Hall sensors provide commutation feedback to the amplifier so phase switching remains synchronized during operation.

The housing uses a frame size of 3.25" square, and the C-coded version uses a metric mounting pattern for installation. The motor is supplied with no brake, so load holding during power loss must be handled by the drive or by external hardware. It also has no shaft seal, which makes it better suited to clean environments or to machines that provide sealing at the driven assembly. A 2-inch stack length helps keep the package compact, and the standard winding supports mid-power servo duty with balanced current demand and thermal rise. These features make the motor suitable for compact motion axes where fast response and straightforward integration are important.
