Product Description

Pacific Scientific is an industrial giant that manufactures state of the art automation equipment and industrial motors.

The P21NRXF-LNF-NS-00 is a powerful stepper motor that produces an impressive 0.82 Nm holding torque. The motor belongs to the famous POWERMAX II series manufactured by the company. The P21NRXF-LNF-NS-00 is a NEMA 23 stepper motor and produces the largest amount of torque when compared to other motors of the same size range. This model has very advanced features that significantly increase the motor’s efficiency. There is an option of using a solid rotor with this model. Using a solid rotor gives a marked increase in the motor's damping and stiffness. It also enables the motor to generate a high amount of torque at considerably low speeds. A solid rotor also gives the benefit of fast settling. With a phase resistance of 2.61 ohms, the motor operates on a peak current of 1.51 A.

The P21NRXF-LNF-NS-00 uses a specially designed low inertia rotor. Because of this, the P21NRXF-LNF-NS-00 is able to produce the highest acceleration rates among NEMA 23 motors. This model comes with the Sigmax Technology that is used to increase the available torque from a motor. With a highly cost economical motor design, the motor has a honed stator ID that is used to maintain a concentric air gap. The motor’s heat dissipates rates are also significantly higher because of an encapsulated stator. The P21NRXF-LNF-NS-00’s bearings have been designed to sustain continuous cyclic loading. With its 30 mm oversized bearings, the motor has an increased fatigue life. Other motors of this class come with a much smaller bearing size (22 mm). The P21NRXF-LNF-NS-00 is a long-lasting stepper motor that is suitable for all industries.
