Two words that can best describe Pacific Scientific’s products – safety and reliability. These are products you’ll purchase and for a very long while, you will neither need repair or replacement. Designed to deal with the modern automation problems, they are made by experienced, skilled and enthusiastic engineers using high-quality materials. The outcome is highly efficient products with exceptional durability and outstanding performance. Also with the utilization of high-end technology and modern methods and approaches, the motion products are made to be innovative and multipurpose. Once you purchase Pacific Scientific products, you are guaranteed of innovativeness, technical expertise, and long-lasting products.

The M21NRXB-LNN-NS-00 stepper motor model is designed and manufactured by Pacific Scientific using Sigmax technology. As such, it is among the stepper motors with the largest diameter of NEMA 23, making it ideal for high radial and axial loads. Also, its oversized bearings of 30mm increase the bearings’ lifespan as well as that of the unit itself.

Another important aspect of the M21NRXB-LNN-NS-00 motor is its technical information. This, when adhered to, enhances the unit’s performance and durability but when ignored, can lead to user injury and unit damage. During operation, you can choose either a series, unipolar or a parallel connection. At the DC, the current of the motor stands at 2.3-4.6 Amps while the holding torque range is estimated to be between 0.68 Nm to 0.97Nm +/-10%. The motor’s thermal resistance is 5.50C/watt while the phase resistance is 0.32 to 1.28 Ohms. The M21NRXB-LNN-NS-00 motor’s rotor inertia is 0.012 kgm2 x 10-3 while the typical phase inductance is 1.0 to 4.0 Mh. When manufactured, the estimated weight of this stepper motor is 1.5lbs.
