Product Description:
The P21NRXA-LSS-NS-00 is a stepper motor from Pacific Scientific Company. Coming in the POWERMAX II series, it provides the highest torque and acceleration in the market. The P21NRXA-LSS-NS-00 is a P2 model that features a standard NEMA mounting which improves mounting flexibility on a wide range of surfaces. It comes in a low inertia design which is ideal for high acceleration applications in the factory. With the oversized 30mm bearings, the lifespan of the bearing and the motor is extended. The motor is CE compliant so you can use it in different factory settings.
The P21NRXA-LSS-NS-00 comes in a compact package providing high performance while saving on factory space. Thanks to its brushless motor design, it is maintenance-free reducing the cost of maintenance to a minimum. The stepper action involves small and precise 1.8-degree increments of 200 steps per revolution. It has a maximum speed of 3000rpm for medium and low applications. The 0.30 to 0.51Nm torque range makes it ideal for a wide range of applications without further modifications. The P21NRXA-LSS-NS-00 provides numerous benefits such as faster machines, lower energy consumption that reduces the cost of production, lower system cost, and compact machines that do not take much space.
It comes with the largest bearing system in the market that allows it to withstand high side loading and thrust loads. This improves the lifespan of the motor, makes it an excellent option for leadscrew applications, and reduce machine cost since you can directly mount the loads without the need for load support bearing and couplings. The Pacific Scientific motor also comes with high voltage insulation that eliminates joints and gaps that are prone to failure. This allows the combination of the P21NRXA-LSS-NS-00 with standard or high-performance drives.
