Product Description:

The N33HCHK-LNK-NS-00 is a POWERPAC N Stepper Motors series unit produced by Pacific Scientific. As a hybrid stepper motor, it converts pulse-train commands from a controller into accurate incremental rotation for factory conveyors, pick-and-place heads, or valve actuators. The device belongs to the stepper class rather than servo hardware, so it achieves position control through detent torque and controlled excitation rather than closed-loop feedback, offering a straightforward motion source for industrial automation. The model fits mid-range torque applications where repeatability and low-speed smoothness are more critical than dynamic feedback bandwidth. This operating method suits applications that use open-loop motion control and consistent indexing moves.

Each energization cycle advances the rotor by 1.8°, giving 200 discrete steps per mechanical revolution. With three magnetic stacks and a laminated rotor, the motor delivers 12.4 Nm of holding torque to retain load position when current is applied. A NEMA 34 face with heavy-duty mounting holes integrates directly with standardized brackets, while a housing length of 171 mm permits deeper coil slots required by the standard winding. The unit is supplied without a shaft seal, so it is intended for clean, enclosed equipment where contact with fluids is unlikely.

Electrical insulation is rated at 100 Megohms, and the windings withstand 340 Vdc, supporting reliable isolation when the motor is driven by modern microstepping amplifiers. The stator bolts into a 3.38 in. square frame, and power reaches the coils through a 4-lead parallel arrangement terminated in a System MS connector, supporting straightforward wiring. Position sensing is not provided, so the drive must rely on the motor's inherent ±3% step accuracy. This layout is common in equipment that prioritizes simple drive electronics over onboard feedback devices. A single shaft finished with a straight key transfers torque to couplings or pulleys.
