Stepper Motors
Unlike anyone else in the industry, over 50% of our motors are utilized as part of a custom module or assembly. SKC manufactures stepper motors in a wide range of Nema sizes (11, 14, 16, 17, 23, and 34), many step angles (0.9°, 1.8°, 3.6°, 3.75° and 11.25°) and a large spectrum of torque outputs as well.
