Product Description

Pacific Scientific uses exceptional innovation not only to produce motors ideal for present-day applications and applications for future engineering. This enables the company to produce products that are tailored for specific applications and are cost-effective. The P21NRFA-LNN-NS-00 is a POWERMAX II stepper motor that features exceptional Pacific Scientific engineering. It is built with cost-effectiveness, ease-of-use, and versatility in mind making it well-suited for numerous tasks on the factory floor. It provides high-performance thanks to its brushless and maintenance-free design. The 1.8-degree increment provides small, precise, and cost-effective motion control that features 200 steps per revolution.

The P21NRFA-LNN-NS-00 has improved bearing fatigue life thanks to the oversized 30mm bearings. This large bearing design extends motor life and reduces downtime for high performance. It provides high acceleration for demanding tasks owing to its low inertia rotor. The stator that is polymer encapsulated and exposed laminations provide exceptional thermal dissipation that improves the lifespan of the motor and lower downtime. This type features a holding torque of 0.81Nm, a rated current of 5.6A, and a phase resistance of 0.23ohms. It has a Detent torque of 0.028Nm, 5.5C/Watt thermal resistance, and a weight of 0.68kg.

The P21NRFA-LNN-NS-00  has a polymer end bell that features threaded inserts. This provides greater flexibility when mounting the encoder and the brake options. It features an insulation resistance of 100Megaohms, an insulation voltage rating of 340Vdc, and an insulation classification of class B. Stepper motors with this class can withstand high-temperature levels of up to 130 degrees. The operating temperature of this Pacific Scientific motor is -20 to 40 degrees. some of the options available for this stepper motor are leadwire connection, rear shaft extension, and encoder mounting provisions.
