Product Description:

The R33GENC-R2-NS-NV-00 is a servo motor produced by Pacific Scientific as part of the R Servomotors series. As a rotary actuator, it converts electrical power from a matched drive into mechanical motion for positioning and speed-regulated tasks in automated machinery, conveyors, and pick-and-place stations. The motor is suited for mid-frame axes where compact size and repeatable motion are important. Its closed-loop operation supports stable speed control and accurate response during changing load conditions.

A continuous stall torque of 2.5 N·m supports static holding or slow-speed feed motions without overheating, while the rated speed of 3000 rpm indicates the shaft velocity available at nominal bus voltage before field weakening. For rapid indexing, the motor can deliver a peak torque of 6.54 N·m for short periods, which gives additional acceleration to overcome inertia during brief demand spikes. The rotor’s mass moment of inertia is 0.093 kg·m² × 10⁻³, a low value that helps the axis change speed quickly and reduce energy loss during reversals. Mechanical integration is simplified by the 3.25-inch square frame, which matches standard NEMA mounting patterns so brackets or couplings usually do not require custom machining.

The sealed aluminum housing follows the vendor’s Style C configuration and uses a 3-inch stack length, which supports continuous output without forced cooling. Torque is generated by rare-earth samarium-cobalt magnets, a material choice that maintains strong magnetic flux across a wide temperature range and resists demagnetization during peak loads. Position feedback is supplied by a size 21 frameless resolver, and its analog sine-cosine signals give the drive absolute shaft angle for closed-loop control. The motor uses English mounting hardware, has no holding brake, ships without a shaft seal, and uses a standard winding. No secondary feedback device is included.
