Product Description:

The R34JENC-R2-NS-NV-00 belongs to the R Servomotors series manufactured by Pacific Scientific. It is a brushless servo motor intended for closed-loop motion axes that require quick acceleration and precise position control in automated machines and test equipment. By converting electrical drive commands into regulated rotary movement, the unit links digital controllers with mechanical loads and maintains the response consistency expected in modern industrial automation.

A continuous stall capability of 3.2 Nm sets the steady-state torque the motor can deliver without overheating, making it suitable for holding demanding loads at zero speed. During rapid indexing or start-stop duty, the motor can reach a peak of 8.30 Nm, giving extra torque margin for overcoming inertial or frictional spikes. The rated operating point is 2300 rpm, where winding temperature and iron losses remain within design limits during continuous operation. Dynamic behavior is helped by the rotor’s moment of inertia of 0.11 × 10⁻³ kg·m², allowing swift changes in velocity while minimizing overshoot. Magnetic flux is produced by samarium cobalt rare-earth magnets, which provide high energy density and stable demagnetization resistance at elevated temperatures.

The motor uses a 3.25" square frame with a stack length of 4 inches, dimensions that fit standard English mounting patterns. It is built in Housing style C, and the shaft area is supplied without a seal to reduce friction in clean environments. Primary feedback is provided by a size 21 frameless resolver, and no secondary device is fitted, so all position data comes from the resolver windings. The motor does not include a holding brake, which suits applications that rely on drive torque or external clamping at rest. The medium winding type balances current draw and thermal rise, and the English mount style matches imperial fasteners for straightforward assembly.
