Product Description:

The R34KENC-R2-NS-VS-00 servo motor is manufactured by Pacific Scientific and belongs to the R Servomotors series. As a brushless AC unit, it converts electrical power from a matched drive into rotary motion for positioning, velocity, and torque control in automated machinery such as indexers, pick-and-place heads, and packaging axes. Resolver feedback and a medium-high winding support closed-loop operation over a wide speed range while maintaining accurate response during repeated starts, stops, and load changes. This arrangement suits motion systems that need stable servo performance without adding a separate external feedback package.

Under continuous duty, the motor can deliver 3.2 Nm of stall torque, allowing steady operation without exceeding thermal limits. For transient moves, it can reach 8.30 Nm of peak torque, which provides additional force during acceleration and short indexing events. Rated operation reaches 4000 rpm, giving a useful balance of shaft speed and general-purpose servo performance. Rotor inertia of 0.11 kg·m² × 10⁻³ helps the motor respond quickly during reversals while remaining manageable in lightly coupled drive systems. The magnetic stack extends 4 inches, giving the motor an active iron length that supports the output produced by its winding design.

The square housing measures 3.25" square, which supports mounting on compact frames that follow NEMA 23 patterns, and the English bolt pattern helps align the motor with existing brackets. A C housing style places the connectors at the rear and keeps the exterior smooth for tight machine spaces. Rare earth (samarium cobalt) magnets provide strong magnetic flux for responsive servo operation and consistent torque production. Position data is supplied by a size-21 frameless resolver, and no secondary feedback device is installed. A Viton shaft seal resists oil and coolant ingress to protect the internal bearings during continuous production.
