Product Description:

The N33HRFL-LNK-NS-00 belongs to the POWERPAC N Stepper Motors series from Pacific Scientific. Classified as a stepper motor, it converts digital pulse trains from a drive into discrete angular movements, giving deterministic positioning in industrial automation tasks such as material indexing and light-duty presses. The unit uses a heavy-duty NEMA mounting style that fits standardized flanges, and its standard construction follows the common layout used across the series. This operating method makes repeatable indexing possible when the controller sends a known number of pulses to the windings.

The motor sits inside a NEMA 34 housing with a 3.38 in. square frame, providing rigid support for the shaft and bearings during repetitive start-stop duty. Each revolution is divided into 200 full steps per revolution, and the rotor advances by a 1.8° step angle on each full step. This step arrangement supports incremental positioning in applications that rely on commanded pulse counts. The laminated rotor and three-stack magnetic circuit produce a holding torque of 12.4 Nm, so the shaft can hold position when motion stops. A standard winding set balances current demand with heat rise, and the 171 mm overall length provides space for the coil mass used at this torque level.

Closed-loop sensors are not fitted, so accuracy depends on the intrinsic ±3% step precision and on proper drive current tuning. Electrical insulation is rated for 340 Vdc, and insulation resistance reaches 100 Megohms, supporting use on grounded or floating supplies. The eight conductors exit through regular leadwires in an 8-lead configuration, allowing series or parallel phase connection. This leadwire arrangement provides flexibility when matching the motor to different drive current and voltage requirements. The motor also uses a laminated rotor and a single straight-key shaft without a shaft seal, so external sealing is required when fluids are present. The three-stack stator and regular leadwire connection style suit straightforward open-loop control applications.
