Product Description:

The R33GEB0-R2-NS-VS-02 is a servo motor built by Pacific Scientific within the R Servomotors series. Designed for closed-loop motion axes, this motor converts electrical drive commands into precise rotary movement for industrial automation equipment such as pick-and-place heads, feeders, or packaging stations. Its electromagnetic layout, feedback interface, and compact mechanical envelope support rapid indexing and repeatable positioning in automated cycles. In a matched servo system, the motor works with the drive to correct speed and position errors as load conditions change.

This model supplies a continuous stall torque of 2.5 Nm, which is the steady torque available without overheating while the shaft is held at zero speed. That output is useful when the axis must resist load at standstill without continuous shaft rotation. When rapid acceleration is demanded, the motor can reach a peak torque of 6.54 Nm for short intervals. At the rated speed of 3000 rpm, the rotor inertia of 0.093 kg·m² × 10⁻³ supports quick reversals and responsive motion. For power-off holding, the integrated brake uses a 100 V dc coil, so the axis can remain in place without an external clamp.

The housing measures 3.25 inches square, allowing it to fit standard inch-based mounting patterns in compact machine frames. A Viton shaft seal helps limit contaminant ingress in damp or coolant-prone areas. Rotor flux is produced by rare earth samarium cobalt magnets, which offer strong magnetic stability at elevated operating temperatures. Position feedback is delivered through a frameless resolver size 21, which sends rotor position signals to the drive without adding a secondary feedback device. This style of feedback is often valued for durability in electrically noisy environments and under repeated thermal cycling. The standard winding arrangement and simplified feedback package help keep cabling straightforward while preserving servo response in repetitive motion service.
