The stepper motor, is a brushless synchronous electric motor in direct current, that can divide its rotation in a large number of steps. The motor position can be accurately controlled without having to resort to closed loop control (feedback) if the size and type of engine are chosen correctly for the application. The stepper motors hybrid with permanent magnet are for the most part produced according to the flanges defined by the NEMA standard.
The NEMA17 standard is widely used in industrial machinery such as CNC machines and for all applications in which is required precision in the angular displacement and the speed of rotation as for example in the field of 3D printing.
