NEMA 17 refers to a standardized size for stepper motors, defined by the National Electrical Manufacturers Association (NEMA). The '17' denotes the faceplate size, which is 1.7 x 1.7 inches (43.2 x 43.2 mm). NEMA 17 motors are widely used in applications requiring precise motion control, such as 3D printers, CNC machines, and robotics. While NEMA 17 specifies only the physical dimensions, the electrical characteristics like voltage, current, and torque can vary among different models. In cybersecurity contexts, understanding hardware standards like NEMA 17 is important when securing devices that incorporate such motors, as vulnerabilities may arise from physical interfaces or firmware controlling these components.
