Product Description:
The R46GSNA-HS-NS-NV-03 is a servo motor produced by Pacific Scientific within the R Servomotors series. As a torque-generating element in industrial automation, it converts drive current into controlled rotary motion for indexing tables, pick-and-place arms, and other position-controlled axes. The unit is intended for use as the actuator coupled to a digital drive controller. It uses brushless motor technology with high-density rare-earth magnets.
At the core of its mechanical output, the motor supplies a continuous stall torque of 7.6 Nm, letting a drive hold loads indefinitely without exceeding thermal limits. For short accelerations, it can surge to a peak torque of 20.2 Nm, providing headroom for rapid indexing moves. Dynamic response is aided by a rotor inertia of 0.40 kg·m² × 10⁻³, so speed changes demand relatively low energy from the servo amplifier. A compact 4.25-inch square frame sets the mounting interface and fits tightly packed machines. Torque density is enhanced by samarium cobalt magnets, whose high flux supports the stated torque levels and resists demagnetization at elevated temperatures.
Commutation and coarse position data are provided by Hall sensors, allowing controllers to initialize motion without high-resolution encoders. Because there is no brake, the axis must rely on drive torque or external holding hardware to maintain position when power is removed. The stacked lamination packet measures 6 inches in length, pairing with the standard housing style to balance torque and overall weight. A configuration with no shaft seal means the motor is intended for clean, dry environments, and external sealing is required where fluid ingress protection is needed. With no secondary feedback and a standard winding, the motor suits applications that use basic commutation feedback.
