Product Description:

The N41HRFM-LNK-NS-00 is a stepper motor manufactured by Pacific Scientific within the POWERPAC N Stepper Motors series. It translates digital step commands into incremental rotary motion, enabling precise open-loop positioning for indexing tables, feeders, and packaging heads. Designed for integration with micro-stepping or full-step drives, it serves applications that call for dependable torque delivery and straightforward wiring without the complexity of closed-loop feedback. Open-loop operation is useful in systems that need repeatable indexing and do not require onboard position feedback from the motor.

The housing conforms to the NEMA 42 standard and has a 4.325 in. square frame, giving the motor a broad flange for heavy-duty mounting. Overall body length is 99 mm, and the internal architecture uses a laminated rotor in a 1-stack configuration to balance inertia and torque density. A single shaft with a straight key is supplied, and no shaft seal is fitted, so external protection may be required in wet areas. The keyed output supports secure torque transfer to couplings, pulleys, and similar drive components. The motor provides holding torque of 11.5 Nm and uses standard windings with a 1.8° step angle and an accuracy of ±3%.

The windings withstand up to 340 Vdc relative to the frame and maintain an insulation resistance of 100 megohms, which helps reduce leakage in damp environments. A full revolution is divided into 200 discrete steps, allowing predictable micro-stepping ratios in positioning tasks. Eight phase conductors exit as an 8-lead leadwire bundle, which supports series or parallel coil connections and keeps wiring flexible for different drive arrangements. This lead configuration also allows the motor to be matched to different current and voltage requirements at the drive. Feedback components are omitted, so applications that require encoder signals must use external sensors.
