Product Description:
Pacific Scientific manufactures the N32HRFK-LNS-NS-05 in its POWERPAC N Stepper Motors series. The motor is intended for indexing tables, automated conveyors, and other motion axes where controlled incremental rotation positions a load without closed-loop feedback. In these systems, the drive electronics issue pulse trains, and the motor converts each pulse into discrete shaft movement that advances tooling or workpieces in a predictable manner. This open-loop operating method suits applications where repeatable step execution is sufficient and direct position feedback is not required.
The housing has a 3.38 in. square frame and follows the NEMA 34 bolt pattern, so it can fit many legacy mounting plates without modification. Internally, the rotor is laminated and uses a two-stack arrangement with a standard winding to produce 200 full steps per revolution. When phase current is held, the magnetic circuit develops 8.6 Nm of holding torque to resist back-drive during dwell periods. Electrical insulation measures 100 megohms, supporting reliable operation in humid plant areas. The motor uses the standard construction style of the series and connects through regular lead wires, while heavy-duty NEMA mounting shoulders transfer belt or gear loads directly into the machine frame. Since no encoder is fitted, position is determined by pulse count, and the ±3% step accuracy suits many packaging or material-handling duties.
The insulation system also withstands test potentials up to 340 Vdc, so common DC bus voltages do not compromise dielectric strength. An 8 lead exit allows either series or parallel wiring to suit torque or speed requirements. Overall length is 133 mm, which helps preserve installation depth while still providing a rigid, single-ended shaft for couplings or pinions. Each command pulse advances the shaft by the basic 1.8° step angle, giving predictable incremental motion during repetitive indexing tasks. The laminated rotor and regular lead-wire connection support steady open-loop operation in conveyors, indexers, and similar machinery.
