Product Description:

The R24GENA-R1-NS-NV-01 is a rotary actuator delivered by Pacific Scientific within the R Servomotors series. As a brushless AC unit, it translates drive current into controlled torque for positioning and velocity loops in industrial automation cells, packaging axes, and light-duty material-handling stations. This configuration code identifies a round-frame model with English mounting and a standard housing style for use in multi-axis machines. It is intended for applications that require repeatable rotary motion in a compact servo package.

Its mechanical output includes a continuous stall torque of 1.1 Nm, so the motor can hold that load at zero speed without thermal overload when the shaft is locked. During rapid load changes, it can deliver up to 3.07 Nm of peak torque for short acceleration periods. The round frame measures 2.0 in. OD, which suits compact gearheads and fixtures that follow NEMA 23 footprints. Rotor speed is rated at 3000 rpm, matching common inverter drive ranges for precise velocity control. The magnetic stack length is 4 inches, which gives the motor its active iron length and contributes to the overall housing length. The windings follow Pacific Scientific’s standard pattern, and the unit is supplied without a holding brake.

The rotor has a reflected inertia of 0.021 × 10⁻³ kg·m², which helps servo amplifiers tune responsive motion on light loads. Flux is produced by samarium cobalt rare-earth magnets, providing high energy density and stable performance over a wide temperature range. Primary position data comes from a size 15 frameless resolver, and the transmitter-type resolver provides absolute angle information with good resistance to electrical noise. The motor is supplied without a shaft seal, so it is best suited for clean environments or for use with external sealing on the driven mechanism. The unit has no secondary feedback, which keeps the feedback arrangement simple for compatible servo systems.
