The Pacific Scientific M21NSXA-LNN-NS-02 is a NEMA 23 Frame stepper motor, part of the POWERMAX II Series. Its frame, sized at 2.3”, is equipped with a single-ended smooth shaft, and its standard winding type makes it adaptable for various applications. Its operational features include 200 full steps per revolution, a full step angle of 1.8°, and a wide temperature range of -20 to 40°C. The motor also boasts large 30mm bearings, resulting in a lifespan exceeding 10K hours under specified axial and radial loads. The M21NSXA-LNN-NS-02 supports a maximum radial load of 20 lb. and axial load of 13 lb. It's capable of encoder installation, ideally HEDS 5600 series encoders, enabling real-time position and motion status updates. It employs a standard NEMA flange type mounting for easy installation and utilizes 2 amperes of current under bipolar series connection.
