Product Description:
The N33NRFC-LNN-NS-00 is a hybrid stepper motor produced by Pacific Scientific within the POWERPAC N Stepper Motors series. It has a regular lead-wire arrangement and contains no internal feedback device, so position verification depends on open-loop control strategies. As a two-phase incremental actuator, it converts digital pulse trains from indexers or drives into fixed angular increments, enabling pulse-based positioning on pick-and-place modules, packaging axes, and small gantries. Its laminated rotor and standard construction support consistent torque production. The single shaft accommodates commonly used couplings without requiring a specialized mechanical interface.
With a holding torque of 12.4 Nm, the motor can maintain the load position at standstill without an additional brake, which is useful for vertically mounted loads or tensioning stations. Each command pulse advances the shaft by a 1.8° step, and 200 full steps per revolution provide granular control for low-speed indexing. Average step accuracy is ±3%, supporting repeatable movement in fixtures that rely on cumulative precision. The 3.38-inch square frame corresponds to the NEMA 34 envelope, facilitating direct coupling to standardized gearboxes and mounting plates. The motor has an overall length of 171 mm. Its three-stack design provides additional rotor volume for higher magnetic flux and increased detent stiffness during microstepping.
The electrical insulation is rated for 340 Vdc, allowing the windings to tolerate the high bus voltages used by compatible bipolar drives while maintaining separation between the coils and housing. The stator leads exit as a regular eight-lead bundle, allowing the phases to be wired in series or parallel for current-limited or voltage-limited applications. The motor has an insulation resistance of 100 megohms, which helps limit leakage current in humid operating conditions. Its shaft is supplied without a shaft seal, minimizing friction in installations where external enclosures protect the motor from contaminants. This unsealed shaft arrangement is intended for controlled environments rather than locations where the output end is directly exposed to dust, liquid, or debris.
