1. Components of the 20(BYG1.8) Stepper Motor

1. Stator: The stator is the stationary part of the motor that consists of multiple windings that generate a magnetic field when energized.
2. Rotor: The rotor is the rotating shaft that interacts with the magnetic field produced by the stator. It can be permanent magnet or variable reluctance type.
3. Coils: The stator coils are typically supplied with power in a sequence that allows for controlled movement and positioning of the rotor.

2. Working Principle

1. Electromagnetic Induction: When current flows through the stator coils, a magnetic field is created, pulling the rotor towards the energized coil.
2. Step Control: By sequentially powering the stator coils, the rotor is forced to move in discrete steps, enabling precise positional control.
3. Direction and Speed: Changing the sequence of energizing the coils can reverse the direction of the rotor’s movement, while the speed of rotation can be controlled by varying the frequency of the input signals.
