Product Description:

The R46GCNA-R2-NS-NV-00 is a servo motor produced by Pacific Scientific within the R Servomotors series. It is intended for industrial automation axes where precise torque and speed control are required for conveyors, pick-and-place heads, or gantry joints. When connected to a compatible drive, the motor provides controlled rotary motion, and its electrical feedback allows the controller to close the position loop accurately.

The motor’s continuous stall capability is 7.6 Nm, which is the maximum torque it can apply continuously without thermal overload. For short-duty peaks, it can reach 20.2 Nm, providing added torque for acceleration or temporary load changes. Dynamic response is supported by a rotor inertia of 0.40 kg·m²×10⁻³, which helps balance quick speed changes with stable operation. The motor uses a compact 4.25-inch square frame that fits common machine layouts, and the laminated stack extends to 6 inches to support higher magnetic flux and torque output. The housing style is standard, and the motor does not include a factory-installed holding brake, so stopping force must be handled by the drive or external mechanical components.

High-energy magnets made from rare earth samarium cobalt generate the motor’s magnetic field and support strong peak performance. Mechanical attachment follows the NEMA Face pattern, allowing the motor to bolt directly to gearboxes or machine plates without adapters. Position feedback is provided by a frameless resolver size 21, which supplies rotor angle information with good noise immunity, and no secondary feedback device is installed. Because the shaft has no seal, the installation must protect the front bearing area from coolant and dust. The copper conductors use a standard winding arranged for common drive voltages and reduced resistive losses during normal duty.
