Product Description:

The R46GEBA-HS-NS-NV-00 is a brushless AC servo motor manufactured by Pacific Scientific within the R Servomotors series. As a servo actuator, it converts drive current into controlled torque and speed so that automated axes can position quickly and repeatably in packaging, material-handling, and machine-tool equipment. The motor’s construction supports closed-loop operation with digital drives and is sized for medium-duty industrial motion tasks where precise feedback, integrated braking, and standardized mounting simplify installation. It delivers rotary motion to couplings, pulleys, and gearheads inside multi-axis assemblies.

At stall, the winding can maintain a continuous torque of 7.6 Nm without exceeding its thermal limits, providing a baseline for static holding or low-speed feed tasks. During rapid acceleration, the electromagnetic system can deliver a peak of 20.2 Nm, providing overhead for overcoming friction and load inertia. The laminated steel core is built into a 4.25" square frame that fits standard NEMA edge dimensions, while rotor inertia of 0.40 kgm² × 10⁻³ balances quick response with stable velocity regulation. A stack length of 6 inches increases the active copper volume, allowing higher continuous power without enlarging the mounting footprint.

Magnetic flux is produced by rare-earth samarium-cobalt magnets, so demagnetization is minimized at elevated temperatures and the motor sustains consistent torque density over time. An integral 100 V DC brake engages mechanically when power is removed, holding vertical or suspended loads without external clamps. Rotor position data reaches the drive through Hall sensors, enabling six-step commutation in systems that do not require high-resolution encoders, and there is no secondary feedback channel. Because the design includes no shaft seal, the motor should be installed in clean environments or paired with an external sealing element. The housing style, winding type, and English flange dimensions follow Pacific Scientific’s standard configurations for the R series.
