Product Description:

The R46G0NA-R2-NS-NV-00 is a servo motor built by Pacific Scientific as part of the R Servomotors series. Designed for positioning and velocity regulation on packaging lines, pick-and-place axes, and other motion loops, it converts drive current into precise mechanical rotation while returning position data through its integrated resolver. The motor combines controlled torque output with a compact mechanical envelope and built-in feedback for general motion applications.

At continuous stall, the rotor can deliver 7.6 Nm without exceeding its thermal limit, and transient demands can be met with a peak of 20.2 Nm. Those torques are produced in a 4.25-inch square frame that simplifies interchange with other NEMA-format motors. Magnetic flux is generated by a rare-earth samarium cobalt rotor set, giving high energy density while keeping the moving mass low, and the combined rotor and shaft inertia is 0.40 × 10⁻³ kg·m². Position feedback is provided by a frameless resolver mounted directly to the shaft, allowing analog sine-cosine signals to be read by standard resolver-to-digital converters. The housing style is standard, the motor has no shaft seal, and it is supplied without a factory-installed brake, making it suitable for dry, cabinet-mounted installations where external holding devices are used.

The laminated stack measures 6 inches in length, so the motor fits applications that impose strict axial space limits while still requiring moderate torque. Because there is no brake, dynamic stopping must be supplied by the drive or the machinery, and the open endbell also reflects the absence of secondary feedback hardware. A plain output shaft is used, and the lack of sealing must be considered if oil mist or coolant is present. The combination of a standard housing, a standard winding, and the rare-earth rotor supports general automation duty with stable torque output and predictable motor response.
