R45GENA-R2-NS-NV-00

R45GENA-R2-NS-NV-00 is a Pacific Scientific servo motor in the R Servomotors series. Its 4.25-inch-square frame provides the motor’s mounting envelope, while the 5-inch stack length indicates the axial length of its active motor section. The motor uses an English mounting type for installation with corresponding imperial mounting dimensions. Its housing has a standard style, and the standard winding supports its specified operating characteristics. There is no shaft seal, so the shaft opening does not have additional sealing against contaminants.

The motor produces 5.7 Nm of continuous stall torque for sustained operation at zero speed and up to 15.1 Nm of peak torque for short periods of higher load. Its inertia is 0.31 × 10⁻³ kg·m², which indicates the rotor’s resistance to changes in rotational speed. Rare-earth samarium-cobalt magnets generate the motor’s magnetic field and support torque production.

Primary feedback is provided by a size 21, transmitter-type frameless resolver, which supplies rotor position information for commutation and motion control. There is no secondary feedback device. The motor has no holding brake, with the brake configuration factory preassigned, so it does not mechanically hold the shaft when motor power is removed.
