DC Motor
A DC motor is an electromechanical device that converts direct current electrical energy into mechanical rotation using electromagnetic principles. It operates based on the interaction between magnetic fields and current-carrying conductors, typically featuring a rotor (armature) and stator (field magnets). DC motors are widely used for applications requiring precise speed control, high starting torque, and reversible operation.
Developers should learn about DC motors when working on robotics, automation systems, IoT devices, or embedded projects that involve motion control, such as drones, CNC machines, or conveyor belts. They are essential for applications needing variable speed, position control, or low-speed torque, and are often interfaced with microcontrollers (e.g., Arduino, Raspberry Pi) using motor drivers like H-bridges.
