Product Description:

The R33GMNC-R2-NS-NV-00 belongs to the R Servomotors series from Pacific Scientific. As a brushless AC servo motor, it supplies closed-loop rotary motion to indexing tables, pick-and-place axes, and similar automation stages. The brushless design supports repeatable position and velocity control in automated equipment, and the feedback loop allows the connected drive to correct motion errors during operation.

This model delivers a continuous stall torque of 2.5 Nm, meaning it can hold that load indefinitely without overheating when the rotor is locked. During acceleration or brief overloads, the drive can reach a peak torque of 6.54 Nm, giving additional torque for startup inertia. Its rated speed is 3000 rpm, which is the upper continuous operating velocity before thermal limits are reached. The rotor’s reflected inertia is 0.093 kg·m²×10⁻³, a low figure that permits fast speed changes and simplifies tuning of the connected drive amplifier. A compact 3.25-inch square frame and a 3-inch stack length fit the motor into tight machine spaces, while housing style C and the standard winding match common R-series electrical arrangements.

The motor is supplied with no brake, so any power-off holding force must be provided externally. Output torque is generated by a rare earth samarium cobalt magnet set that offers high flux density and stable thermal behavior. Rotor position is reported by a frameless resolver size 21, which sends absolute sine-cosine signals to the motion controller, and there is no secondary feedback channel. Because the design follows metric mounting conventions and omits a shaft seal, external guarding is needed if liquid ingress is possible. Housing style C and the standard winding keep the motor in a standard R-series configuration.
