A DC Motor is an electrical machine that converts direct current (DC) electrical energy into mechanical energy. DC motors are widely used in various applications due to their simplicity, controllability, and efficiency. They come in different types, including brushed and brushless motors, each suited for specific applications. DC motors are essential components in industries such as manufacturing, automotive, robotics, and consumer electronics.
