Product Description:

The R33GENC-HS-NS-NV-00 is a servo motor built by Pacific Scientific as part of the R Servomotors series. Designed for industrial automation, the motor converts drive current into controlled rotary torque for indexing tables and similar motion tasks. It belongs to the manufacturer’s medium-frame offerings, providing compact power where fast acceleration, repeatable positioning, and limited installation space are priorities. Classified as a permanent-magnet AC servo motor, it integrates with matched drives and feedback loops.

The motor delivers a continuous stall torque of 2.5 Nm, allowing it to hold load shafts without overheating during static clamping cycles. When commanded for bursts, it can reach a peak output of 6.54 Nm, supplying extra acceleration for rapid indexing. Rated speed is 3000 rpm, so the drive can maintain synchronous motion with moderate-frequency command signals. Rotor inertia is 0.093 × 10⁻³ kg·m², a value that balances dynamic response with stability in lightly loaded axes. Rare-earth magnets made from samarium cobalt provide high flux density, letting the winding current remain moderate while still achieving the listed torque levels. The unit employs a standard winding set, uses housing style C, and mounts with an English bolt pattern, simplifying interchange in North American machinery.

The frame measures 3.25 inches square, and the magnetic stack extends 3 inches along the shaft axis, so the assembly fits into shallow enclosures while still accommodating the required copper volume. Motion feedback to the drive is furnished by Hall sensors, and no secondary transducer is installed, which streamlines cabling for basic velocity loops. Because the motor is supplied without a brake, the shaft is free when power is absent, and the build includes no shaft seal, limiting ingress protection to the housing alone. This arrangement keeps the feedback package simple and leaves shaft holding to the connected machine or drive system.
