Product Description:
The N33HCHJ-LNK-NS-00 is a stepper motor manufactured by Pacific Scientific as part of the POWERPAC N Stepper Motors series. In automated equipment, it converts pulse commands from a drive into discrete shaft movements, and the omitted encoder option keeps the motor in open-loop operation. This arrangement suits indexing, feed, and positioning tasks that rely on repeatable step commands rather than continuous servo correction. The motor uses a laminated rotor with standard windings, while its single straight-key shaft supports direct coupling to belts, screws, or gearing. A heavy-duty NEMA mounting face secures the housing and helps maintain alignment during high holding-torque applications.
Each electrical pulse turns the rotor by 1.8°, so a full revolution is completed after 200 steps, and the angular error remains within ±3%. The motor has a holding torque of 12.4 Nm, allowing it to resist back-driving when power is applied but motion is halted. The square front section measures 3.38 in. on each side and matches the industry-standard NEMA 34 bolt circle for compatibility with existing brackets. Overall body length is 171 mm, providing room for a three-stack laminated core and the magnetic circuits that increase torque without increasing frame width.
The electrical interface uses a 4-lead parallel configuration terminated in a System MS connector, which provides low-resistance winding paths for higher phase current. This connection style supports the winding layout used in the motor without adding external feedback hardware. The insulation system has a test rating of 340 Vdc and an insulation resistance of at least 100 Megohms, helping the motor withstand voltage transients from chopper drives. The motor has no shaft seal, which reduces friction in clean, dry environments, and the single-shaft design simplifies coupling alignment. Standard construction, a three-stack lamination set, and the lack of feedback devices support dependable open-loop performance without added sensors.
