Product Description:
The R34JENC-TS-ND-NV-00 is a servo motor built by Pacific Scientific as part of the R Servomotors series. This square-frame unit belongs to the manufacturer’s general-purpose brushless motor range and serves as the electromechanical link between a digital drive amplifier and the driven load. By producing commanded torque on demand, it is used to position conveyors, actuate indexing tables, and regulate speed in automated packaging and assembly equipment. Its brushless design also supports repeatable motion with low maintenance and stable response during frequent start-stop cycles.
It supplies a continuous stall torque of 3.2 Nm, meaning the shaft can hold that load indefinitely at rated temperature. For momentary surges, the motor produces up to 8.30 Nm. A rated speed of 2300 rpm balances torque capability with mechanical life and is matched to medium-voltage R-series windings. The motor has a 3.25" square frame, so it fits compact mechanical envelopes, while the laminated core stack reaches 4 inches to raise power density. Rotor inertia is only 0.11 kg·m² ×10⁻³, allowing fast acceleration without demanding excessive drive current. The C housing style, English mounting interface, and medium winding resistance suit the motor to common servo installations that need responsive motion in a compact package.
The magnetic circuit uses rare earth (samarium cobalt) material, which increases flux density and maintains demagnetization resistance during continuous duty cycles. For feedback, the primary device is a Tachsyn resolver-tachometer hybrid that delivers combined velocity and incremental position signals, while the secondary encoder, 500 ppr, line driver output produces differential quadrature pulses for closed-loop position control. Because the motor is supplied without a holding brake and lacks a shaft seal, the surrounding machine must provide load holding at standstill and protect the shaft interface from contamination. This arrangement is best suited to clean installations or to assemblies that already include external protection around the drive end.
