Have you ever wondered what drives the smooth, precise movements of your 3D printer, CNC machine, or robot? The answer is a stepper motor ! In this article, we'll explore the basics of stepper motors. How do stepper motors work? Stepper motors are electric motors that convert digital pulses into precise mechanical movements. They are used in numerous applications, from controlling robots to powering printers and scanners. A stepper motor is made up of two main components; the rotor and the stator. The rotor is the part that moves and usually comprises a permanent magnet or a soft iron core. On the other hand, the stator is the stationary part of the motor and consists of two or more wire coils arranged around a core. The rotor and stator work together to create the stepper motor, with the rotor providing movement and the stator providing power. This construction ensures that the motor can be usedn in various applications, from small robotics to large-scale industrial machines. The...
