Product Description:
The R34JENC-TS-NF-NV-00 is a servo motor produced by Pacific Scientific and belongs to the R Servomotors series. As a brushless AC unit, it provides closed-loop motion in industrial automation for positioning, indexing, and velocity control. The motor is supplied without a holding brake, has no shaft seal, and uses housing style C with an English mounting interface. This arrangement suits machines that use inch-based mounting hardware and rely on external braking or enclosure protection.
The motor delivers a continuous stall torque of 3.2 Nm, enough to hold a load at zero speed without overheating, while its peak capability rises to 8.30 Nm during short acceleration intervals. Rated operation occurs at 2300 rpm, which suits medium-speed axes that need steady velocity under closed-loop control. Dynamic response is supported by a rotor inertia of 0.11 × 10⁻³ kg·m², helping the drive accelerate and decelerate the shaft quickly without excessive current demand. Mechanical integration is straightforward because the frame measures 3.25" square, which fits common machine footprints based on NEMA 34 outlines. Internally, a medium winding balances resistance and inductance for use with standard drive voltages.
The active section is only 4 inches long, which helps keep overall mass low while still accommodating samarium cobalt magnets. This magnetic material maintains stable flux over a wide temperature range and supports responsive servo performance. For feedback, the motor uses a Tachsyn resolver for analog speed and position signals, while a 1000 ppr encoder with line-driver outputs supplies digital incremental data for finer command tracking or redundant monitoring. Having both feedback devices can simplify integration with control systems that need analog reference signals as well as higher-resolution digital feedback.
