Product Description:
The R34KEAC-HS-NG-NV-00 is a servo motor manufactured by Pacific Scientific for the R Servomotors series. Built for closed-loop axis control in industrial automation, the unit delivers accurate velocity and position regulation for pick-and-place robots, feeders, and web-handling equipment. It interfaces with brushless servo drives and uses onboard feedback devices to synchronize stator currents with rotor position. This arrangement supports fast responses during starts, stops, and direction changes.
The motor provides a continuous stall torque of 3.2 Nm without thermal overload. For rapid indexing, the rotor supplies a peak torque of 8.30 Nm for short intervals, allowing drives to accelerate loads without oversizing. Mechanical speed is limited to 4000 rpm, balancing rotor stress with bearing life. A rotor inertia of 0.11 kg·m² × 10⁻³ supports a responsive control loop and allows command filters to be tuned for tight stiffness. The stator and flange occupy a 3.25-inch square frame that fits into crowded machine layouts, and a 24 V DC brake locks the shaft during a power loss. Primary commutation is provided by Hall sensors, and the medium-high winding is suitable for drives with bus voltages from 160 to 320 V. An imperial bolt pattern supports installation in place of compatible NEMA units. The C housing style provides standard protection, while the absence of a shaft seal reduces viscous drag at speed.
Torque density is supported by the rotor’s rare-earth samarium cobalt magnets, which maintain magnetic flux at elevated temperatures and permit shorter electrical time constants. The laminated stack has an axial length of 4 inches, providing the flux volume required by the medium-high winding without increasing the frame diameter. Secondary feedback is supplied by an encoder with 1024 ppr line-driver outputs, giving the drive fine resolution for position interpolation. Its line-driver signals also provide digital noise immunity across long cable runs. The encoder works with the Hall sensors to provide the commutation and motion data required by the servo drive.
