Centurion NSM Series

NEMA 23, 34, 42 and 56 frame sizes allow easy integration of NSM Series servo motors with other NEMA format components. The NSM family also provides an ideal servo alternative to stepper motors. Continuous torque of 1.6 to 52 lb-in (0.18 to 5.9 Nm) with speeds up to 6,000 rpm are available. Typical applications include semiconductor manufacturing, material handling, web processing, robotics and packaging.
