STEPPER MOTOR WORKING PRINCIPLE: This explains the working principle of a stepper motor, which rotates in fixed angular steps by sequentially energizing stator windings. The rotor, a permanent magnet, aligns itself with the active stator poles based on the input pulse sequence. In the top illustration, the coil activation pattern follows a specific order, resulting in clockwise rotation. Reversing the sequence, as shown in the bottom image, causes counterclockwise rotation. The truth table along

This shows how to control a stepper motor by energizing its windings in a specific sequence. The tables list the step angles and the corresponding states of coils (X, X̅, Y, Y̅) for clockwise and counterclockwise rotation. By grounding the right coils in order, the rotor steps through precise angles, enabling accurate position control. #ElectronicsEducation #electronicsrd #steppermotor | Electronics Education
