A NEMA 17 stepper motor is a type of stepper motor that adheres to the National Electrical Manufacturers Association (NEMA) standard size 17, which specifies a mounting face of 1.7 inches (43.2 mm) square. Stepper motors are widely used in various applications, including robotics, 3D printing.

A NEMA 17 stepper motor is a type of electric motor that is widely used in various motion control applications, such as 3D printers, CNC machines, robotics, and automation systems. NEMA 17 steppers typically have more torque than smaller variants, such as NEMA 14 and have a recommended driving voltage of 12-24V.
