Product Description:

The R46HCNA-R2-NS-NV-00 is a servo motor produced by Pacific Scientific within the R Servomotors series. In automated machinery, this unit provides commanded torque and speed so motion controllers can position loads with repeatable accuracy. Its electromagnetic design, combined with resolver feedback, lets it react quickly to changing process demands while maintaining tight velocity regulation across production cycles. It fits applications such as pick-and-place heads, indexing tables, and packaging axes where compact framing and high dynamic torque density are required.

At stall, the motor delivers 7.6 Nm of continuous torque, a level that can be applied indefinitely if winding temperature remains within its rating. For short transients such as acceleration or disturbance rejection, the electromagnetic stack supports a peak of 20.2 Nm, giving nearly three times the continuous margin to overcome inertia or friction. The rotor has a mass moment of inertia of 0.40 kg·m²×10⁻³, so the drive amplifier can tune current loops without excessive overshoot. Mechanical geometry is set by the 4.25-inch square frame, which allows installation on NEMA size 4 motor plates, while the laminated core depth reaches 6 inches to increase copper volume and thermal path for the rated torque values.

The magnetic circuit uses rare-earth samarium cobalt magnets, raising flux density and keeping demagnetization risk low at high temperatures. The motor uses a NEMA face mount, letting it bolt to gearboxes or brackets without alignment collars. A high-speed winding lowers inductance so current rises quickly under drive command. Position and velocity are reported by a frameless resolver in size 21, eliminating the need for a secondary feedback device. The motor is supplied without a factory-installed brake or shaft seal, and the housing uses a standard open construction for cabinet-mounted installation.
