Product Description:

The R34JENT-TS-LA-NV-01 is a brushless motor produced by Pacific Scientific within the R Servomotors series. The unit supplies commanded torque and speed to gantries, conveyors, and other motion stations, allowing a drive controller to regulate position through electrical feedback. By translating electrical control signals into mechanical rotation, it fulfills the central actuation role in industrial automation cells. It operates with a compatible amplifier and feedback device to maintain precise velocity under varying load conditions.

Its electromagnetic output begins with a continuous stall capability of 3.2 Nm, ensuring the shaft can hold static loads without loss of synchronization. For short transients, it rises to a peak of 8.30 Nm, giving extra acceleration margin during indexing moves. Rated mechanical velocity is 2300 rpm, a speed chosen to match mid-range belt or gear reductions. Rotor inertia is limited to 0.11 kg·m²×10⁻³, so the drive can change speed quickly while still rejecting disturbances. Torque is developed with magnets made of rare earth samarium cobalt, a material that sustains magnetic flux at elevated temperatures. The motor is supplied without a holding brake, and there is no shaft seal, so external measures are required where static retention or fluid exclusion is critical.

A compact footprint is achieved through its 3.25" square frame and a stack length of 4 inches. The housing uses an English mounting pattern, allowing direct interchange with earlier Pacific Scientific models on NEMA-style plates. Position data is returned by a Tachsyn transducer, giving the drive both tachometer and resolver information for closed-loop control. Internal copper is configured as a medium winding, balancing continuous current against thermal rise for general-purpose duty cycles.
