A Dynamo Motor, also known as a dynamo or generator, is a device that converts mechanical energy into electrical energy through the principle of electromagnetic induction. It consists of several key components, including a rotating coil of wire known as the armature, a magnetic field typically provided by permanent magnets or electromagnets, and a commutator with brushes. As the armature rotates within the magnetic field, an electromotive force (EMF) is induced across the coil due to the changing magnetic flux. This induced EMF causes an electric current to flow through the circuit connected to the dynamo. The commutator, a segmented metal ring attached to the armature, ensures that the direction of current flow in the external circuit remains constant as the armature rotates, thereby producing direct current (DC) output. Dynamo motors find applications in various fields, including power generation, automotive systems, and portable electronics.
