Armatures, also known as armature bars, are crucial components found within certain electrical devices, such as motors, generators, and transformers. Synonyms that can be used to refer to armatures include magnetic cores, pole pieces, and stators. Armatures are designed to rotate when a current is applied to them, which in turn creates an electromotive force. Other synonyms for armatures include rotor, magnetic arm, and solenoid. As a key part of many electrical devices, armatures are responsible for converting electrical energy into mechanical energy, making them an integral part of many modern technologies.
