Product Description:

Pacific Scientific manufactures the N34HRFM-LNK-NS-00 in its POWERPAC N Stepper Motors series. The unit is a hybrid stepping motor that indexes its rotor in fixed electrical increments so a controller can command position, speed, or torque without relying on an encoder. This discrete motion capability is used in material feeders, labelers, and light assembly stations where stable, repeatable angular positioning under open-loop control is acceptable. Its operating principle makes it suitable for applications that benefit from predictable step-by-step movement and straightforward motion control.

Within the motor’s mechanical envelope, the frame conforms to the NEMA 34 standard, yielding a 3.38 in. square frame that aligns with common gearboxes and couplings. Each electrical cycle advances the rotor by a 1.8° step, so the shaft completes 200 full steps per revolution and provides the basic resolution available to the controller. When all eight windings are energized in full-step mode, the laminated rotor can develop 15.3 Nm of holding torque, allowing the motor to resist load disturbance while stationary. Standard winding design and laminated construction also help reduce detent torque so micro-stepping drives can subdivide each step for smoother low-speed motion.

The housing length is 210 mm, which provides room for its stacked magnetic circuit and supports the motor’s torque density. An 8-lead wiring scheme supports series or parallel phase connections, allowing drive matching across different supply conditions. The magnetic core is built from 4 stacks, which increase available flux paths without enlarging the mounting footprint. Insulation provides 100 Megohms of resistance at room temperature and withstands a 340 Vdc test potential. Heavy-duty NEMA mounting, a single straight-key shaft, regular leadwires, and the lack of a feedback device keep the motor aligned with open-loop step control applications. This arrangement also supports integration where simple electrical hookup and conventional mechanical mounting are preferred.
