Product Description:
The R34KENP-R2-NS-NV-00 is a brushless AC servo motor manufactured by Pacific Scientific within the R Servomotors series. It provides closed-loop rotary motion for indexing tables, pick-and-place actuators, and packaging axes where precise speed regulation is required. The motor uses a medium-high winding, which balances current draw and thermal rise so that it can be paired with a wide range of industrial drives without exceeding typical cabinet dissipation limits. That combination suits motion systems that need repeatable response during frequent starts, stops, and short indexing moves.
Torque capability is anchored by a continuous stall rating of 3.2 Nm. This rating indicates the load the motor can hold indefinitely while maintaining its rated temperature. For rapid acceleration events, the magnetic circuit produces a peak torque of 8.30 Nm, giving the axis extra headroom during cycle changes. A rated speed of 4000 rpm allows direct coupling to moderate-ratio gearboxes or belt drives without exceeding bearing limits. Rotor inertia of 0.11 ×10-3 kg·m² offers a balance between quick response and mechanical stability, which helps reduce overshoot in high-gain control loops. Rare-earth samarium-cobalt magnets support the motor's torque density.
The motor has a 3.25-inch square frame that aligns with English mounting interfaces, which can ease retrofit into older machinery. The housing is rated as explosion-proof, allowing installation in classified areas that contain flammable vapors. Position feedback is supplied by a frameless resolver of transmitter type, size 21, eliminating the need for a secondary device. A stack length of 4 inches helps keep overall weight low. The motor has no shaft seal and is supplied without a holding brake, so external clamping or drive torque must secure the load when power is removed.
