Product Description:

The R46GEBA-R2-NS-NV-02 belongs to the R Servomotors series from Pacific Scientific and functions as a brushless AC servo motor for coordinated motion in automated assembly cells, feeders, and packaging equipment. The unit uses a standard housing style and a standard winding set. Its brushless design supports controlled torque delivery and smooth speed regulation during repeated motion cycles. When paired with a matched servo drive, it converts commanded current into rotary force so the machine controller can regulate position and velocity with precise response.

This model can maintain a continuous stall torque of 7.6 Nm, allowing stable load support when the shaft is held in position. The frame measures 4.25-inch square, which sets the mounting bolt pattern and helps with clearance in multi-axis clusters. A 100 V DC brake is fitted to hold the shaft during power-off or emergency-stop events. Rotor inertia is rated at 0.40 kg·m² × 10⁻³, which supports quick acceleration while keeping control loop tuning manageable. Torque is produced with a rare-earth samarium-cobalt magnet set, which provides high energy density and good thermal stability. The English mounting type mates directly with NEMA-style flanges, and the motor uses a standard housing and winding combination.

For overload events, the motor can reach a peak torque of 20.2 Nm for rapid indexing or recovery before returning to rated levels. Position data is supplied by a frameless size 21 resolver of the transmitter type, and no secondary feedback device is included. The motor has no shaft seal, so it is better suited to clean installations without coolant spray or fine dust. The laminated stack measures 6 inches long, which increases the active magnetic length for higher torque without enlarging the frame. Resolver feedback also supports stable rotor position monitoring across typical servo operating speeds.
